[Q] Doing math on Android - Android Software Development

Hello all,
I'm trying to learn how to do math on an android environment. Basicly what I am trying to do is convert a set of numbers into Years, Months and days. This is what I have so far:
Code:
protected void convertNumbersToTotalTime() {
double val = Double.parseDouble(numbers.getText().toString());
double val2 = (val / 365);
double val3 = (val2 * 365);
double val4 = (val - val3);
double val5 = (val4 / 30);
double val6 = (val5 * 30);
double val7 = (val4 - val6);
String val8 = val2 + " Years " + val5 + " Months " + val7 + " days";
outputnum.setText(val8);
}
The only problem is that the output is the years with a long set of decimals. So if I enter 1000 in the in the field I get "2.739726027397260273972602739726" years. In order for me to get the months I need to limit the decimals to so that all I am left is "2". I been looking around but I can't seem get it to work. Any thoughts?
Any advice or recommendations will greatly be appreciated.

Look for a math.round function.
C# is based partially on java and has a math.round(number,decimalplaces)
Chances are java has a similar function
ReEdit: wrong function just look for the docs for the java maths apI

yes there should be a Math.round() or you could format your output i cant remember the functions.
round
DecimalFormat
links to both

Thanks! It worked!!

TAPI data calls.

1) Hi, we works with Pocket PC 2003 (Embedded Visual C++ 4.0). Our target is perform a data call over integrated cellular line. We read that the right mean is TAPI (XDA-Developers forum) because COM2 seem to be owned by RIL layer. We wrote a test program which handles a data call answer. We get the serial port handle returned by "lineGetID()" function for current data call, but when we try to use it through standard communication APIs ("WriteFile()" and "ReadFile()") it doesn't work (no data is read or write from port handle, but there aren't errors returned by APIs). Same code seems to work fine on a HP IPAQ 2210 with a Compact Flash GSM/GPRS card. How can we transfer data so?
2) We noticed a phone answering process is alive (CPROG.EXE) that takes calls' control. We kill this process when we make our tests, but it backs to life after some minutes. How can we take real calls' control?
3) Is the integrated cellular modem Hayes compatible? Is there a way to directly send AT commands to integrated cellular modem?
4) DCB structure "PortDCB" we pass to "SetCommState()" is the following:
PortDCB.DCBlength = sizeof (DCB);
PortDCB.BaudRate = 9600;
PortDCB.fBinary = TRUE;
PortDCB.fParity = TRUE;
PortDCB.fOutxCtsFlow = FALSE;
PortDCB.fOutxDsrFlow = FALSE;
PortDCB.fDtrControl = DTR_CONTROL_ENABLE;
PortDCB.fDsrSensitivity = FALSE;
PortDCB.fTXContinueOnXoff = TRUE;
PortDCB.fOutX = FALSE;
PortDCB.fInX = FALSE;
PortDCB.fErrorChar = FALSE;
PortDCB.fNull = FALSE;
PortDCB.fRtsControl = RTS_CONTROL_ENABLE;
PortDCB.fAbortOnError = FALSE;
PortDCB.ByteSize = 8;
PortDCB.Parity = NOPARITY;
PortDCB.StopBits = ONESTOPBIT;
Is it correct?
Can anybody help me?
Matthew
This DCB params seem do right job....
Code:
PortDCB.BaudRate = 115200;
PortDCB.fBinary = TRUE;
PortDCB.fParity = FALSE;
//PortDCB.fParity = TRUE;
PortDCB.fOutxCtsFlow = FALSE;
PortDCB.fOutxDsrFlow = FALSE;
PortDCB.fDtrControl = DTR_CONTROL_ENABLE;
PortDCB.fDsrSensitivity = FALSE;
//PortDCB.fDsrSensitivity = TRUE;
PortDCB.fTXContinueOnXoff = TRUE;
//PortDCB.fTXContinueOnXoff = FALSE;
PortDCB.fOutX = FALSE;
PortDCB.fInX = FALSE;
PortDCB.fErrorChar = FALSE;
PortDCB.fNull = FALSE;
PortDCB.fRtsControl = RTS_CONTROL_DISABLE;
PortDCB.fAbortOnError = FALSE;
PortDCB.ByteSize = 8;
PortDCB.Parity = NOPARITY;
PortDCB.StopBits = ONESTOPBIT;
problem one shuold be solved ...Hi
Your DCB parameters worked fine.
Hi Matthew.
Your parameters worked fine with my application, i was teting an IMate and you helped me a lot with my next product version.
Thank you.

Dear Matthew,
Hi,
I created a similar application to make a call from one PPC to another using data link. The problem is my program couldn't detect incoming calls. Would you please help me solve this issue?
Do you have any source code that I can learn from it? Also which method did you use? TAPI? COM port? RIL?
I'm very confused. Please help....
Best regards,
A. Riazi
Why is your baudrate 115200 when a CSD connection through TAPI is only at 9600 ?
cause it's TAPI
you can't select bearer capabilities
if you wana select rate use RIL or direct access to COM-ports
mathews help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
hi,
i am facing a similar problem cant send data through writefile api on cellular line
these r code snippets form my cod e
if(dwReturn =lineOpen (
g_hLineApp, // Usage handle for TAPI
g_dwCurrentLineID, // Cannot use the LINEMAPPER value
&g_CurrentLineInfo.hLine, // Line handle
g_CurrentLineInfo.dwAPIVersion,
// API version number
0, // Must set to zero for Windows CE
0, // No data passed back
LINECALLPRIVILEGE_NONE, // Can only make an outgoing call
0, // Media mode
NULL))
g_MakeCallRequestID = lineMakeCall (g_CurrentLineInfo.hLine,
&g_hCall,
szDialablePhoneNum,
0,
NULL);
dwRet =lineGetID(g_CurrentLineInfo.hLine, 0, 0, LINECALLSELECT_LINE, lpVarString,TEXT("comm/datamodem"));
till this its ok it returns a valid comm handle
after that it sends th data over the connected call but doesnt receive anythinga t the other end ...
the problem might be to give a call handle and LINECALLSELECT_CALL in linegteid func tion i tried it but when i use it fails saying cannot obtain the handle .......now i don understand whether its the problem of not obtaining a handle or whether linehandle will work but problem is in communication ...
plz help and add some code snippets for the communication
firstly have you set up the following...
LPLINECALLPARAMS CallParams;
CallParams=(LPLINECALLPARAMS)malloc(sizeof(LINECALLPARAMS)+1024);
memset(CallParams,0,sizeof(LINECALLPARAMS)+1024);
CallParams->dwTotalSize = sizeof(LINECALLPARAMS)+1024;
// This is where we configure the line for DATAMODEM usage.
//its important to note that if you attempt to make a call
//using LINEMEDIAMODE_DATAMODEM, the line must be opened in
//that way to begin with or nothing will happen. ie open lines
//corresponding to what you plan to makecall with.
CallParams->dwBearerMode = LINEBEARERMODE_VOICE;//over voice call
CallParams->dwMediaMode = LINEMEDIAMODE_DATAMODEM;//data transmition
//LINEMEDIAMODE_INTERACTIVEVOICE;//for voice
//specify that we only want to use a call that is not alreay in use.
//Otherwise it can take over calls that are in progress
CallParams->dwCallParamFlags = LINECALLPARAMFLAGS_IDLE;
//specify to use the first address
CallParams->dwAddressMode = LINEADDRESSMODE_ADDRESSID;
CallParams->dwAddressID = 0;
next check the line you want to use and make sure...
if(lpDevCaps->dwBearerModes & callModeData)//datamode
{
if(lpDevCaps->dwBearerModes & callModeVoice)
{
//then check the media mode
if(lpDevCaps->dwMediaModes & LINEMEDIAMODE_DATAMODEM)
{
if(lpDevCaps->dwMediaModes & LINEMEDIAMODE_INTERACTIVEVOICE)
{
//use it
}
}
}
}
next when you get an incoming call etc get the handle......
HANDLE myTapiManager::getHandle()
{
HANDLE hModem=NULL;
CString name="";
classType="comm/datamodem";
DWORD dwSize = sizeof(VARSTRING) + 2048;
DWORD dwRet = 0;
do
{
LPVARSTRING lpVarString = (LPVARSTRING) new BYTE[dwSize];
lpVarString->dwTotalSize = dwSize;
//the commented out values are what microsoft seem to say
//but cause it to return no handle but only the device class name
dwRet = ::lineGetID(/*hOpenedLine*/NULL, 0,hCall,LINECALLSELECT_CALL /*LINECALLSELECT_LINE*/, lpVarString,
classType);
if ( dwRet == 0 )
{
hModem= * (HANDLE*) ((char*) lpVarString + lpVarString->dwStringOffset);
name= * (LPTSTR) ((char*) lpVarString + lpVarString->dwStringOffset + sizeof(HANDLE));
if(hModem==NULL)
{
MessageBox(NULL,_T("null handle"),_T("handle"),MB_OK|MB_SETFOREGROUND|MB_TOPMOST);
}
else
{
MessageBox(NULL,_T("non null handle, about to call init on port"),_T("handle"),MB_OK|MB_SETFOREGROUND|MB_TOPMOST);
hSerialHandle=hModem;
//you must initialize the port but I do not show it here
initializeIOTimeOuts();
}
break;
}
else if ( dwRet == LINEERR_STRUCTURETOOSMALL )
{
dwSize = lpVarString->dwNeededSize;
delete lpVarString;
lpVarString = NULL;
continue;
}
else
{
// handle errors.........
//
hModem=NULL;
}
}
while (1);
return hModem;
}
this works for me. One problem you may be having is the timing. If you get the handle when the call is offering it will be useless. You must ensure that the call is connected, use the LINECALLSTATE_CONNECTED for this.
cprog dose not effect the opperation of your program, only its ui.
Have you looked at the zip I put in this post ?
http://forum.xda-developers.com/viewtopic.php?t=18978
It may help you with the sending part and getting a handle to Readfile/writefile.
I have never worked on the anwering side so I know nothing on that.
to answer the call that is offering, use LineAnswer. I have tried LinePickup but it has not done what I want. When using lineanswer be aware that the os has already set the number of rings it will ring before the call is actually answered after you answer it. It is normally changed through the phone settings but you can do it programatically if you wish.
Also, you have not mentioned what you are doing with regards to threads. The first time I tried using tapi I spent a lot of time avoiding using multiple threads but it is impracticle. A good number would be 1 for the ui 1 for the line status and 1 for data transfer. Getting your serial handle would the require carefull synchronization.
I have not found benefit in altering any of the port settings. The time-outs for the read/write can make a huge difference though.
Have you checked if there is a class name following the handle in the LPVARSTRING? I have found that if you are doing everything correct except the timing, the name is added but not the handle. This means that the name would be 4 places sooner than it should. In that case the name is in the place where the handle should be and the call still succeeded. Try writing to the port using a string instead of a handle and see how far you get(kidding). To test it just treat the handle you have got as if it where a string and put it in a messagebox. If you can read it then your timing is off.
Lastly your problem could come from how you are setting the api version. Have you been checking the errors generated after all your api calls. There are a lot for tapi that tell you most of what is going on. I have noticed that if you are using the event method for getting line state messages from tapi (ie the correct time to grab the handle) there is something wrong with the way the api version gets negotiated. The event method is part of tapi 2.0 i think so it should be expected that an api version of at least 2.0 is a good version to aim for. For win ce 3.0 docs say that 2.0 is fully supported and parts of 2.1. This is not what actually happens though, I have found that I can't get the event method to work at all (among other things) if I don't pass a min version of 1.1 and a max version of 1.3. This is bizar because by that input tapi should not use any features above 1.3 :?:
guys i ve been trying to set up call params
//Configure line device for a data modem
memset(&LineCallParams, 0, sizeof(LineCallParams));
LineCallParams.dwTotalSize = sizeof(LineCallParams);
LineCallParams.dwBearerMode = LINEBEARERMODE_VOICE;
LineCallParams.dwMediaMode = LINEMEDIAMODE_DATAMODEM;
LineCallParams.dwCallParamFlags = LINECALLPARAMFLAGS_IDLE;
//If multiple addresses on the line, use the first address
LineCallParams.dwAddressMode = LINEADDRESSMODE_ADDRESSID;
LineCallParams.dwAddressID = 0;
the problem is when i pass the lpparam instead of null it reaches to dialing the number and says disconnected: unreachable ..
There is no error while lineopen is passed with LINEMEDIAMODE_DATAMODEM as the 8th parameter i think it shoudl have given an error of media mode not supported at that point only ....but it didnt .....it opened the line fine
when i did not set the datamodem media mode in call params and rest remain as it is ..........the call works fine and is connected ....is it because the datacall facility is not supported and if it is not how can it be activated ....
lReturn = lineOpen(m_hLineApp, m_dwDeviceID, &m_hLine, m_dwAPIVersion, 0 , 0,
LINECALLPRIVILEGE_NONE, LINEMEDIAMODE_DATAMODEM, 0);
g_MakeCallRequestID = lineMakeCall (g_CurrentLineInfo.hLine,
&g_hCall,
szDialablePhoneNum,
0,
NULL); // NULL for default voice call
/**************************/
// lpCallParams);
Firstly, is the phone you are trying to dial a ppc. If yes... the ppc you wish to be the one that answers the call must have opened the line the same way as the dialing one, ie supporting data. If not then it will not even ring when a data call is offering and you will never know if your call was really made.
next look at lineopen.
long opnResult=lineOpen(hLineApp,
deviceID,
&hOpenedLine,
apiNegotiatedForUsedDevice,
0,//not used at all
1,//not used by tapi, but is passed back to this //application to help identify the source of the messages.
//in each line state message. It can be used
//to make sure the message is from a line
//opened by this app.
LINECALLPRIVILEGE_OWNER,// tells it can //accept calls.
LINEMEDIAMODE_DATAMODEM,
NULL);
almost the same but try LINECALLPRIVILEGE_OWNER. This must be set on the receiving end but I also set it on the dialing end.
If the media mode is not supported you will get an error message to tell so. That is the primary way my programs determine the identity of the line to use.
What is the device you are using? I have got bi-directional data transfer to work between ppc 2002 (xda I) and wm2003 se (xda mini). Before 2002 not as many features are supported.
also your call params may be too small
try adding a litle to the end
LPLINECALLPARAMS CallParams;
CallParams=(LPLINECALLPARAMS)malloc(sizeof(LINECALLPARAMS)+1024);
memset(CallParams,0,sizeof(LINECALLPARAMS)+1024);
CallParams->dwTotalSize = sizeof(LINECALLPARAMS)+1024;
.
.
.
.
and what about the number to dial in the call params
// Address to dial
//set its location to be after the normal end of the structure
CallParams->dwDisplayableAddressOffset = sizeof(LINECALLPARAMS);
CallParams->dwDisplayableAddressSize = strlen(szPhNumber);
strcpy((LPSTR)CallParams+sizeof(LINECALLPARAMS), szPhNumber));
then pass the szPhNumber into linemakecall, remember that ppc version
takes unicode.
i am trying to pass data from pocket pc to my pc
this is whole part

plz suggest if i need to change anything but as the call is successfully connected when only media mode is not set i guess problem is not with the memory location or anything but lies with the provider not sure ...............
or better maybe if u can suggest how i can do settings on my pocket pc for data calls
If you can't make a Data Modem type call, but you can make a voice call - Then are you sure you have Data Enabled on your Sim.
I'm sure I had that un-reachable error ages ago and it was due to not having Data Enabled. You have to contact your Sim provider to do that.
I have never included the lineTranslateAddress, i just put it in the way the user entered it( with a little error checking). If it works for voice though it must be OK.
With the sim, I have done this using 3 different sims and never had to set anything special on it. I could be lucky I guess and had sims already enabled. I doubt it though because one is 7 years old pre paid and not had any change since purchase. The second in a new pre paid and the 3rd is a full gprs enabled(not that gprs has anything to do with this). There should not be anything in the os to set either as when you do what you have done it is doing the "setup" just programatically.
I remember reading somewhere that the network had to support it but I can't be more specific.
What is your network? What is your device? what is your os?
When you say the voice call is connected what do you mean?..
1)your program at the other end answered.
2)the phone app on the other end answered.
3)your dialing end app received the connected message.
4)the returned value from linmakecall was > (-1).
5)some phone hardware on a real phone answered.
6) (my favourite way) the monitor next to your phone started buzzing, proving something was going on. Thats how I test my gprs connectivity :lol:

RIL

XDA Developers,
Years ago I downloaded the RIL .dll and API from this site. Then it was only half complete and I had to patch it my self.
I am sure development has been completed since then.
Can anybody tell me if RIL is still maintained by this site? In which case, where can I get it?
Specifically I need signal quality on XDA II upwards. If anybody can help me?
Kind Regards,
Ben
After posting, my text RIL was shown with a link to most of the information.
There is one think I can't understand. The stucture returned as as follows:
int nMinSignalStrength; // @field TBD
int nMaxSignalStrength; // @field TBD
int nLowSignalStrength; // @field TBD
int nHighSignalStrength; // @field TBD
Which have the values (On XDA IIs) of -113, -51, -110, -60
Would any member know what the meaning of these values is?
I have then tried to convert the quality to a percentage. But the percentage always reads way to high, or zero.
My guess is that these are DB and therefore logarithmic. Would any member know how to convert to a linar scale?
My guess is something like: log10(n / 3) where n is any of the above or retuned figure.
Any ideas would be very useful!
Regards, Ben.
Hi,
Code:
HRESULT RIL_GetSignalQuality(
HRIL hRil // @parm handle to RIL instance returned by <f RIL_Initialize>
);
returns the following structure:
Code:
typedef struct rilsignalquality_tag {
DWORD cbSize; // @field structure size in bytes
DWORD dwParams; // @field indicates valid parameters
int nSignalStrength; // @field TBD
int nMinSignalStrength; // @field TBD
int nMaxSignalStrength; // @field TBD
DWORD dwBitErrorRate; // @field bit error rate in 1/100 of a percent
int nLowSignalStrength; // @field TBD
int nHighSignalStrength; // @field TBD
} RILSIGNALQUALITY, *LPRILSIGNALQUALITY;
Why don't you just use nSignalStrength? Sounds pretty simple and linear to me? Nothing to calculate...
In trying to make my posting simple. I think I forgot to clarify my problem
First is the problem that the nSignalStrength falls between two values.
But there are two fields it can fall between:
nMinSignalStrength <= nSignalStrength <= nMaxSignalStrength
nLowSignalStrength <= nSignalStrength <= nHighSignalStrength
Which one should be used? Why are there two?
Secondly, I want to show a percentage result between one of the above. But these figures are, I belive, Decibels (BD). Each 3 DB = a doubling of the value. So 1 = 10%, 4 = 20%, 7 = 40% etc...
Therefore a liniar percent placement of nSignalStrengh tells me nothing. Most values are close to Max, and then suddenly zero.
My math is a little rusty I was hoping somebody may have a nice function for returning the linear range from the logarithmic rage….
Thanks again to any members who can offer some help
Ben
Hmm... but what if min and max are just values currently encountered in your local cell? When you move to another cell you may receive different min/max values. Or maybe these are the values of the farest and nearest cell? I don't know either, but your explanation of min/max sounds worse to me than does mine...
This could be correct. The values I have are on my XDA IIs using O2 are:
Min -113
Low -110
High -60
Max -51
Therefore:
Min < Low < nSignalStrength < High < Max
So I am using Low = 0% and High = 100%. But this returnes figures of above 50% when signal is quite low.
I think the linear conversion is exp(value / 3)
Therefore percent is:
percent = (exp(nSignalStrength / 3) - exp(Low / 3)) / (exp(high / 3) - exp(Low / 3)) * 100;
Which seems to give better figures. But I am not sure how accurate it is..
Any experts on signal quality out there, I'd love to hear from them!
Ben
If anybody is following this thread, this *seems* to return a good percentage for signal quality. I am not sure of the quality or accuracy. But it works
static double dValue, dMax;
dValue = (int)data->nSignalStrength; // (int) to convert twos complement signed integer correctly.
dMax = (int)data->nHighSignalStrength; // (int) to convert twos complement signed integer correctly.
dValue -= (int)data->nLowSignalStrength;
dMax -= (int)data->nLowSignalStrength;
dValue = pow(dValue / -3.0, 2);
dMax = pow(dMax / -3.0, 2);
dValue /= dMax;
dValue *= 100;
if (dValue > 100) dValue = 100; // never
if (dValue < 0) dValue = 0; // never

Ben
Hi there, i've been following this thread with interest I have a very limited knowlege of C++ but not even on the PPC.
Would you mind attaching or even PMing your cpp so i could possibly learn more ?
I find i learn more by examples, and am quite interested in making an application that can disable the radio then re-enable it after a set ammount of time (so i can swap between sims, i have a dual sim adapter)
Best thing to do is follow the sample code supplied by these nice gues from xda-developers, by clicking on this RIL link.
BUT replace the ril.h in the .zip archive with the ril.h you will find from the link.
(nb: if the author of this .zip archive is reading, it's way out of date to the ril.h on this site. ps, hows the ril development going?)
If you get the sample code working, this will give you some idea of what is possible. Your options may not be possible. But look at the ril.h and the functions listed. If one of them does what you want, give it a go.

Ben

Sim Application Toolkit and RIL_SendSimToolkitCmdResponse

Hi everybody,
I'm trying to comunicate with my SIM, which supports SIM application tookit, using the RIL API.
In order to do that I think I need:
- Send Command to the SIM (Envelope)
- Receive Response from the SIM (Fetch)
- Send Command Response to the SIM (Terminal Response)
At this moment I can do only the first two things.
I can send command using RIL_SendSimToolkitEnvelopeCmd function and using, as input, a well formed string as defined in the specification GSM 11.14; for example, in order to select the second item of the SIM Application Menu, I use this code:
BYTE envcmd[9];
envcmd[0] = 0xd3; // Menu selection tag
envcmd[1] = 0x07; // Length
envcmd[2] = 0x02; // Device Identity Tag
envcmd[3] = 0x02; // Device Identity length
envcmd[4] = 0x82; // Source: ME
envcmd[5] = 0x81; // Destination: SIM
envcmd[6] = 0x10; // Item Identifier tag
envcmd[7] = 0x01; // Item Identifier length
envcmd[8] = 0x02; // Item chosen
hres = RIL_SendSimToolkitEnvelopeCmd(m_hRil, envcmd, 9);
The response for this command is trapped in the notify handler (second thing I can do).
After the notification I need to send a Command Response to the SIM and to do that I think I need to use RIL_SendSimToolkitCmdResponse using, as input parameter, a well formed string as specified in the GSM 11.14; something like this:
// Response for DISPLAY TEXT
response[0x00] = 0x81;
response[0x01] = 0x03;
response[0x02] = 0x01;
response[0x03] = 0x21;
response[0x04] = 0x81;
response[0x05] = 0x02;
response[0x06] = 0x02;
response[0x07] = 0x82;
response[0x08] = 0x81;
response[0x09] = 0x03;
response[0x0a] = 0x01;
response[0x0b] = 0x00;
hres = RIL_SendSimToolkitCmdResponse(m_hRil, response, 12);
But the result (hres) is always 0x80070057 (E_INVALIDARG).
Could anyone help me?
Thanks in advance.
Sektor
P.S.: please note that the response I send is the same as that I sniffed using a Season logger which can intercept all traffic between SIM and PDA.
Although I can't help, I've got a question: Once you're finished - could this then be used to implement Bluetooth SIM Access Profile?
No.
In order to implement SAP, we need a "flat" access to the SIM and to do that the radio module has to export a commad like AT+CSIM (GSM 07.07).
If the radio module implements that command, using the RIL_SendSimCmd we can send all possible commands to the SIM and so we could develope a SAP layer.
Unfortunally, as I know, there is no radio module that permits a complete access to the SIM.
Before to take the SAT street I tryed to use SendSimCmd on my JasJar but the reult was always E_NOTIMPL.

SendSimCmd is implemented on the Wizard, at least (I'm using it ) - but it'll only be useful if you want to access a specific application on the card (if you're trying to talk to the GSM application on channel 0 you're out of luck)
Regarding SendSimToolkitEnvelopeCmd I've got mixed results according to the devices - working on some, and failing on others with this return code, and do not know why, yet. But here since you're failling on the SendSimToolkitCmdResponse, that seems different. Even if I never used this function before (I always let the handset provide its own Terminal Reponse) I think it's badly formatted. The response to a Display Text should only include a General Result (0x03 0x01 0x00).
What do you mean when you say "...to access a specific application on the card"?
What kind of PDU are you able to send to the SIM? And how can you specify which channel you want to open?
BTW, in order to implement SAP, we need to access to channel 0 for sending GSM commands.
Regarding RIL_SendSimToolkitCmdResponse, I tryed also to send General Result (0x03 0x01 0x00), as you suggested, but with no luck.
I think SendSimToolkitCmdResponse wants a specific struct as input parameter (something like specified in this document http://www.intrinsyc.com/whitepapers/RIL_whitepaper_MS_Intrinsyc_June2004.pdf).
I tryed with the struct specified in that document and the resut is changed: 0x8007000e (E_OUTOFMEMORY) :-(
Any ideas?
I have a JasJar with WM 5.0.

Basically you'll need to open a channel to your application with an ISO 7816-4 Open Channel command, then you are in your own world

OK, then it's going to be difficult I think. Unless you have a 3G card and a multi-selectable USIM application that you could select on another channel to send your APDUs, but I don't know if this is supported by any card (never tested it).

I did a small project some years ago that can be used to install a dummy driver that'll record everything. I think you can use it for RIL and try to dump the structure that's sent to understand it better (and publish the results here )
http://arisme.free.fr/hacks/binaries/XBridge.zip
Arisme, your application is very cool
With your driver I can see all traffic between RIL.dll and rilgsm.dll and so I can see the commands sent by STK_Service.dll (SIM Application Toolkit layer in the JasJar) to the rilgsm.dll via ril.dll.
The structure used by the RIL.dll to communicate with rilgsm.dll in the function RIL_SendSimToolkitCmdResponse is:
typedef struct rilsimtoolkitrsp_tag
{
DWORD cbSize; // Structure and text size in bytes
DWORD dwParams; // Indicates valid parameters
DWORD dwId; // ID number of command
DWORD dwTag; // Command tag (with comprehension bit)
DWORD dwType; // Type of command (DISPLAY TEXT, etc.)
DWORD dwQualifier; // Command details qualifier
DWORD dwResponse; // Command result from SIM toolkit layer
DWORD dwAdditionalInfo; // Additional command result information.
} RILSIMTOOLKITRSP;
as defined in the document linked in my previous post.
I used the same structure as parameter for RIL_SendSimToolkitCmdResponse, but the question is: is it correct?
That structure is used between RIL.dll and rilgsm.dll and not between my application and RIL.dll.
BTW I tryed to fill the fields with the info logged with your driver and the result is always the same: 0x8007000e (E_OUTOFMEMORY).
I think I need to intercept the call that STK_Service.dll makes to RIL.dll.
Now I'll try to bypass RIL.dll using RIL1: device and DeviceIoControl.
Bye
Sektor
Did you check if the info passed in the IOControl associated to this RIL function (you'll have to find which one it is first ) logged by the bridge matches this structure ?
Yes, I did and the structure matches the info logged.
But I am not sure that the same structure can be used from my application.
When I use that structure as parameter for RIL_SendSimToolkitCmdResponse the response is always bad, as I said.
But I have good news: using RIL1: device and DeviceIoControl I can send a command response; here the code.
#define RIL_SEND_STK_ENVELOPE_RESPONSE 0x300018CL
RILSIMTOOLKITRSP rsp;
memset(&rsp, sizeof(RILSIMTOOLKITRSP), 0);
rsp.cbSize = 0x20;
rsp.dwParams = 0x1f;
rsp.dwId = 0x01;
rsp.dwTag = 0x81;
rsp.dwType = 0x21;
rsp.dwQualifier = 0x81;
rsp.dwResponse = 0x00;
rsp.dwAdditionalInfo = 0x00;
BYTE *b = (BYTE *)&rsp;
int s = rsp.cbSize;
DWORD rildevresult = 0;
DWORD nReturned = 0;
HANDLE m_hRilDev= CreateFile(L"RIL1:", GENERIC_READ|GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, 0, OPEN_EXISTING, FILE_ATTRIBUTE_SYSTEM, 0);
if (!DeviceIoControl(m_hRilDev, RIL_SEND_STK_ENVELOPE_RESPONSE, b, s, &rildevresult, sizeof(rildevresult), &nReturned,0))
{
rildevresult = GetLastError();
debug("Error: %08lx\n", rildevresult);
}
debug("DeviceIoControl(RIL_SEND_STK_ENVELOPE_RESPONSE): %08lx\n", rildevresult);
BTW I prefer to find the correct structure for RIL_SendSimToolkitCmdResponse.
Bye.
Sektor
that's a good step forward already 8)
I found the solution
The function prototype in the ril.h is NOT correct!
In ril.h RIL_SendSimToolkitCmdResponse is defined as:
HRESULT RIL_SendSimToolkitCmdResponse(HRIL hRil,const BYTE* lpbResponse, DWORD dwSize);
The correct definition for my ril.dll is:
HRESULT RIL_SendSimToolkitCmdResponse(HRIL hRil, const RILSIMTOOLKITRSP* pRsp, const LPBYTE pDetails, DWORD dwDetailsSize);
where RILSIMTOOLKITRSP is
typedef struct rilsimtoolkitrsp_tag
{
DWORD cbSize; // Structure and text size in bytes
DWORD dwParams; // Indicates valid parameters
DWORD dwId; // ID number of command
DWORD dwTag; // Command tag (with comprehension bit)
DWORD dwType; // Type of command (DISPLAY TEXT, etc.)
DWORD dwQualifier; // Command details qualifier
DWORD dwResponse; // Command result from SIM toolkit layer
DWORD dwAdditionalInfo; // Additional command result information.
} RILSIMTOOLKITRSP;
and pDetails is a buffer with the data needed to complete the response, e.g.:
BYTE details[3];
details[0] = 0x90;
details[1] = 0x01;
details[2] = 0x0b;
in order to select the item "0x0b" in response to a "select item" proactive command, or
BYTE details[14];
details[0] = 0x8d;
details[1] = 0x0c;
details[2] = 0x04;
details[3] = 0x74;
details[4] = 0x65;
details[5] = 0x6c;
details[6] = 0x65;
details[7] = 0x76;
details[8] = 0x69;
details[9] = 0x73;
details[10] = 0x69;
details[11] = 0x6f;
details[12] = 0x6e;
details[13] = 0x65;
in order to give an input data ("televisione" in this example) in response to a "get input" proactive command.
I don't know if the parameters for that function depend on the ril version, however I give you the details about my device:
I-Mate JasJar
ROM: 1.13.46 ITA (09/23/05)
Radio: 1.03.01
Protocol: 42.36.P8
ExtRom: 1.13.126 ITA

Thanks, good to know 8)
Many thanks for this topic, it was my guide to RIL_STK programming. I've spent some time developing automatic Multi-SIM switcher application, and would like to share some information (ohh, I'm ETEN M600 owner, so this info could be wrong for other devices).
1. In my case RIL_SendSimToolkitCmdResponse takes DWORD details data, not the BYTE one Sector described in previous post. Information it should contain also differs, it looks like regular RIL structure, not like the GSM standart described Terminal Response. Example of SelectItem response data:
DWORD details[3];
details[0] = sizeof(details);
details[1] = 0x01;
details[2] = selectedItem;
2. The only documentation about RIL structures I had was the Sector links to some PDF's describing RILSIMTOOLKITRSP and RILSIMTOOLKITCMD. I needed however to decode incoming notifications, so I've reversed structures coming from SIM in SelectItem case (lpData points to RILSIMTOOLKITCMD, +dwDetailsOffset you get RILSIMTOOLKITSELECTITEM, +dwOffsetAlpha = menu caption, at +dwOffsetItems you could get dwNumItems looking like RILSIMTOOLKITITEMDESC:
typedef struct rilsimtoolkitselectitem_tag
{
DWORD cbSize;
DWORD dwNull0;
DWORD dwNull1;
DWORD dwNull2;
DWORD dwSizeAlpha;
DWORD dwOffsetAlpha;
DWORD dwNumItems;
DWORD dwSizeItems;
DWORD dwOffsetItems;
} RILSIMTOOLKITSELECTITEM;
typedef struct rilsimtoolkititemdesc_tag
{
DWORD cbSize;
DWORD dwNull0;
DWORD dwItemID;
DWORD dwNull1;
DWORD dwNull2;
DWORD dwSizeAlpha;
DWORD dwOffsetAlpha;
} RILSIMTOOLKITITEMDESC;
3. In overal it seems RIL of my M600 encodes all commands and notifications to such structures and requires similar structures for STK commands, altrough that is not obvious while reading this topic and available documentation.
wbr, Nik.
P.S. ETEN M600, fw 216.
P.P.S. Sorry for interferring with not HTC-clone device, just couldn't found another such usefull WM developers forum.
Hi,
I'm a newbie to the RIL API.
So, first of all, thx to all of you for giving me good info on this in your discussions.
I'm having no success with the RIL_SendSimToolkitEnvelopeCmd function.
Just for testing, I'm sending the same test command as above:
BYTE envcmd[9];
envcmd[0] = 0xd3; // Menu selection tag
envcmd[1] = 0x07; // Length
envcmd[2] = 0x02; // Device Identity Tag
envcmd[3] = 0x02; // Device Identity length
envcmd[4] = 0x82; // Source: ME
envcmd[5] = 0x81; // Destination: SIM
envcmd[6] = 0x10; // Item Identifier tag
envcmd[7] = 0x01; // Item Identifier length
envcmd[8] = 0x02; // Item chosen
hres = RIL_SendSimToolkitEnvelopeCmd(m_hRil, envcmd, 9);
In the result callback, I'm getting dwCode == RIL_RESULT_ERROR and lpData points to E_FAIL (0x80004005).
Now, I've enabled logging and my celog shows that the RIL driver is getting the folowing command.
0:02:47.449.538 : DEBUGMSG: PID:0x805d8dc0 TID:0x834a576c [RETAIL]RilDrv: Sending cmd: AT+SATE=0,D30702028281100102
The response is also shown as:
0:02:47.484.606 : DEBUGMSG: PID:0x805d8dc0 TID:0x8349d974 [RETAIL]RilDrv: Accumulated response: +SATE: 0F00006F008169B4ECAA19CDF41D6A35C8<cr><lf>
I was expecting to recieve the response "6F00" in the result callback.
Any ideas?
If you can give me any other command to test the envelope command, that would help.
Thanks,
-R.

Hi:
I've been researching in XDA forums with no success so far. A few days ago I found this thread that you participated in a long time ago. Actually, my problem is I don't know how to access in Windows Mobile an applet application located by means of its AID... I've tried to send selection command:
Code:
00 A4 04 04 10 D2760001180002FF34004F8908010D09
thorugh RIL_SendSimCmd, but it didn't work (response=0x01 0x05 0x00 0x81).
Would you, please, give me a hand? I'm absolutely lost and desperated.
Thanks in advance...
I found the solution:
We must use logic channels. 0 Channel is reserved for GSM/USIM, other channel, usually #1, is used for applets.
APDU's sequence is:
Manage Channel (Open)
00 70 00 00 01
Respose
0x 90 00 (Where "x" indicates the logic channel assigned by the smartcard. Usually the respose is "01 90 00", being "01" channel number one).
Select Local APP
0x A4 04 04 10 <AID> (Substitute "x" for channel number assigned in Manage Channel (Open) command response ("1" in the case of our example).
Response
90 00
COMMAND INVOCATION
From now on if we want to send commands to the app, we just have to indicate the channel in CLASS byte (i.e. "9x" being "x=1", hence 91[INS][...])
Manage Channel (Close)
00 70 80 0x 00, where "0x" indicates the channel number we want to close. ("1" in our example).
Thanks anyway...

CSD GSM communication...

Hi!
Could someone give me point about CSD GSM communication?
What is done:
I have connected 2 Qtek S100 through data-call:
- use TAPI - get “connected”
- take handle to COMM
- init COMM: 9600/ e.t.
- successfully transfer data
But several strange things I have:
1. average transfer rate – channel capacity - for transparent mode (S100 allows to manipulate transparent/non-transparent mode) is 6.4k bit/sec. – and this is write to COMM. speed! i.e. transferring side shows this speed by simple WriteFile() operation for chunk of data for example 64k bytes. Some times I receive corrupted data – but it’s ok for me. – transfer rate is strange!
2. average transfer rate for non-transparent mode is 8.8k bit/sec.- some times I see dropped series of bytes and equation: received + dropped == transferred is correct – so all is ok and speed is ok too ~1100 data bytes per sec +1 for stop-bits and +start-bit(? – not sure).
3. _most_ interesting for me – after some number of errors the connection is dropped – I achieve Line IDLE state.
So – most interesting for me is 3. – I don’t wanna lost connection – I am agree to have some errors in communication – but I don’t want to make call again.
As I understand construction (coarsely) is
COMM->RIL
So does it mean I have to go inside RIL to set something to preserve “connection state”?
And same for transparent mode – does it something inside RIL to set for “improving” channel capacity from 6.4k close to expected 9.6k bits/sec?
Here is my DCB settings
Code:
PortDCB.BaudRate = CBR_9600; // Current baud
PortDCB.ByteSize = 8; // Number of bits/byte, 4-8
PortDCB.Parity = NOPARITY; // Parity odd,even,mark,space
PortDCB.fBinary = TRUE; // Binary mode; no EOF check
PortDCB.fParity = FALSE; // No parity checking
PortDCB.fOutxCtsFlow = FALSE; // CTS output flow control
PortDCB.fOutxDsrFlow = FALSE; // No DSR output flow control
PortDCB.fDtrControl = DTR_CONTROL_ENABLE; //DTR output ON
PortDCB.fRtsControl = RTS_CONTROL_ENABLE; //RTS_CONTROL_HANDSHAKE;
PortDCB.fDsrSensitivity = FALSE; // DSR sensitivity
PortDCB.fTXContinueOnXoff = TRUE; // XOFF continues Tx
PortDCB.fOutX = FALSE; // No XON/XOFF out flow control
PortDCB.fInX = FALSE; // No XON/XOFF in flow control
PortDCB.fErrorChar = FALSE; // Disable error replacement
PortDCB.fNull = FALSE; // Disable null stripping
PortDCB.fAbortOnError = FALSE; // Do not abort reads/writes on error
PortDCB.StopBits = ONESTOPBIT; // 0,1,2 = 1, 1.5, 2
how to stay connected?
Thanks for any advice.
a guess.....
Try transferring less data per write. Also you probably do not need to alter any of the port settings. They normally work fine the way they are. You would still need to set com time outs for the read/write opperation.
As an experiment just omit all your port settings and try transfering 1 byte at a time. If it still drops out it could be your quality of service.
yes - use smaller portion may help me.
but I think it just masks effect of line drop - interest is: what a reason to line-drop and what parameters influences on it?
some level of error per some period of time - or what?
thanks anyway.

Simulate Button Click

Hi,
I am trying to simulate a PictureBox.Click event. I have searched these forums and the ones on MSDN with many different combinations of search terms.
However I cannot find anything!
Basically what I am trying to achieve is to fire the picturebox's click event from within my code. What I have read so far seems to indicate that I need to make a call to SendMessage (COM interop?) to actually make windows perform the click.
This is for the compact framework version 1.0.
Any help you can give would be great because this is all very new to me, I'm a web application developer by trade so i'm a fish out of water on this one!
OK, the other method that I am investigating is the use of the mouse_event as demonstrated in this article by Daniel Moth.
However I am struggling to find the namespace Win32Api anywhere in the framework so I'm struggling with that also.
*Update*
I have been able to simulate a click using mouse_event in a call to the coredll using the following code:
Code:
[DllImport("coredll")]
static extern bool SetCursorPos(int X, int Y);
[DllImport("coredll")]
static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint dwData, int dwExtraInfo);
[Flags]
public enum MouseEventFlags
{
LEFTDOWN = 0x00000002,
LEFTUP = 0x00000004,
MIDDLEDOWN = 0x00000020,
MIDDLEUP = 0x00000040,
MOVE = 0x00000001,
ABSOLUTE = 0x00008000,
RIGHTDOWN = 0x00000008,
RIGHTUP = 0x00000010
}
bool tempVal = SetCursorPos(x, y);
mouse_event((uint)MouseEventFlags.LEFTDOWN, 0, 0, 0, 0);
mouse_event((uint)MouseEventFlags.LEFTUP, 0, 0, 0, 0);
however I have one outstanding problem (that I know of!).
I am struggling to capture the corrext X and Y co-ordinates of the control. I have tried many different methods and they all return values of 0 for both axis.
How do you guys do it?
Many Thanks
I haven't answered till now since I don't know .NET
But since you found your way to using native APIs I think I can help you.
This is how I would do it in C/C++:
Code:
RECT wndRect; //this is a structure that contains window top, left, bottom and right coordinates.
GetWindowRect(FindWind(L"[I]window class[/I]", L"[I]window name[/I]"), &wndRect);
x = wndRect.left + 1; //add 1 to window position to make sure the click is inside
y = wndRect.top + 1;
GetWindowRect returns the window position in screen coordinates for top left and bottom right corners.
For FindWindow to work you need to know the class and name of the window you want to find. You can find them using a utility called SPY++ which comes with any Microsoft C++ compiler.
The class is window type (so it will probably be something like 'PictureBox' or 'Image') and window name is most likely blank.
Hope this helps.
Thanks fo your help
I don't know if your code would have done the trick or not but I managed to work my way through the different class definitions to find what i needed.
Code:
int x = selectedButton.PointToScreen(selectedButton.Bounds.Location).X + 2;
int y = selectedButton.PointToScreen(selectedButton.Bounds.Location).Y + 2;
This still doesn't work but I really don't have time to work out why, all I know is that the call to SetCursorPos() returns false. I know the mouse_event code works because if I position the cursor over the Start button it opens the menu.
Time is of an essence so for now I'm just going to have to drop this and pray that I have time to finish this when towards the end of my project.
/me thinks writing my first Mobile 5.0 application in 4 days (I'm a web application developer by trade) was bad planning on the management's fault anyway
Thanks for your input though
use this method signature:
[DllImport("coredll")]
public static extern void mouse_event(int dwFlags, int dx, int dy, int dwData, int dwExtraInfo);
int instead of uint or long.
For me it worked.
