XDA II - GSM in which Port ?.

Hi,
GoodDay. I am using O2 XDAII, I am want to send some data through GSM. For that I want to know, GSM is situated in Which Port ?.......
So that i can Open the port(COM1 or Com2) and send the some AT commands into it.
or is there any there way to Open the GSM and send data
Kindly Let me know..
Thanks

Over GSM, you have two options; dial-up and GPRS..
None of these uses COM ports in the way that you are thinking..

GSM is located at COM2. But to enable communication with it on XDA2 you'll need to send IOCTL to RIL. Here is a code from one of my test applications.
Code:
#include "stdafx.h"
int HexToInt(char R)
{
if(R>='0' && R<='9')
return R-'0';
if(R>='a' && R<='f')
return R-'a'+10;
if(R>='A' && R<='F')
return R-'A'+10;
return 15;
}
int Hex2ToInt(char *R)
{
return ((HexToInt(R[0])<<4)|HexToInt(R[1]))&255;
}
bool IsHex(char C)
{
if(C>='0' && C<='9')
return true;
if(C>='A' && C<='F')
return true;
return false;

Hi,
Good Day.. I got your code..... First of all i convey my thanks to you.
I need some more clarification from your side.
Kindly let me know in details
I am not able understand
Why we need to use RIL & IOCTL Funct?
how your sending "AT" Commands in your Code?( explain to me in details) If i want to add some more AT commands like( AT+CSQ or AT^SCKS?) means how do i add these command and where?...
if you have sample code kindly send to [email protected]
anticipating your reply,
Thanks & regards,
Rajesh. S

Using COM port GSM access to change outgoing line
Is it possible to alter the outgoing number (read from the SIM card) on the GSM by accessing the COM port?
Is there a utility that already does this? Is there a way of altering settings/phone to be able to change the outgoing number? Or a ROM image that allows you to do this?
I have no understanding whatsoever of the radio stack, so I wouldn't know where to start if I were to write a utility to do so.
Cheers,
Jason

@jman,
No that is not possible. The reason is that the phone does not send its caller ID over the air. What happens is that a pseudo random number (called TMSI) is assigned to the mobile phone. The mobile phone sends its TMSI for identification and the MSC (Mobile Switching Centre) does the mapping for the TMSI to calling MSISDN (techno term for mobile phone number).
However, if you are a really good programmer and know your phone internal GSM functioning very well. Then you can spoof the TMSI. Meaning, you should listen to the Paging Messages that are being received on the PCH and get the TMSI from them and then generate a CHAN_REQ based on one of those TMSI. If you want to know more about it, then I suggest that you read a document called GSM04.08 from www.3gpp.org .
Please note that whatever I have written above is valid for a GSM/GPRS/EDGE network only.

Bluetooth Programming...

This is for the C/C++ developers out here...
i need to connect a PocketPC to a PC via Bluetooth. Looking at various samples from the Windows Platform SDK and the Windows Mobile SDKs, i came up with the following server (PC) and client (PDA) codes:
Server Code (WinXP):
Code:
WSAData wsaData;
SOCKADDR_BTH sa;
int namelen;
SOCKET sock;
SOCKADDR_BTH sockaddr;
int size = sizeof(sockaddr);
if (WSAStartup(MAKEWORD(2, 2), &wsaData) == SOCKET_ERROR)
return false;
BluetoothHost_Socket = socket(AF_BTH, SOCK_STREAM, BTHPROTO_RFCOMM);
if (BluetoothHost_Socket == INVALID_SOCKET)
return false;
memset (&sa, 0, sizeof(sa));
sa.addressFamily = AF_BTH;
sa.port = 0;
if (bind(BluetoothHost_Socket, (SOCKADDR *) &sa, sizeof(sa)))
{
closesocket(BluetoothHost_Socket);
return false;
namelen = sizeof(sa);
if (getsockname(BluetoothHost_Socket, (SOCKADDR *)&sa, &namelen))
{
closesocket (BluetoothHost_Socket);
return false;
}
BluetoothHost_ClientListCount = 0;
if (listen(BluetoothHost_Socket, 5))
return false;
sock = accept(BluetoothHost_Socket, (SOCKADDR *) &sockaddr, &size);
}
Client Code (WinCE):
Code:
WSAQUERYSET querySet;
HANDLE hLookup;
char buffer[1000];
DWORD bufferlength;
WSAQUERYSET *results;
SOCKADDR_BTH *btaddr;
if (WSAStartup(MAKEWORD(2, 2), &wsaData) == SOCKET_ERROR)
return false;
memset(&querySet, 0, sizeof(querySet));
querySet.dwSize = sizeof(querySet);
querySet.dwNameSpace = NS_BTH;
BluetoothQuery_DeviceCount = 0;
if (WSALookupServiceBegin(&querySet, LUP_CONTAINERS, &hLookup) == SOCKET_ERROR)
return false;
while (BluetoothQuery_DeviceCount < BLUETOOTHQUERY_MAXDEVICES && !BluetoothQuery_Cancel)
{
bufferlength = sizeof(buffer);
memset(buffer, 0, sizeof(buffer));
results = (WSAQUERYSET *) &buffer;
if (WSALookupServiceNext(hLookup, LUP_RETURN_NAME|LUP_RETURN_ADDR, &bufferlength, results) == SOCKET_ERROR)
{
int result = WSAGetLastError();
break;
}
btaddr = (SOCKADDR_BTH*)results->lpcsaBuffer->RemoteAddr.lpSockaddr;
BluetoothQuery_DeviceAddrList[BluetoothQuery_DeviceCount]=btaddr->btAddr;
if (results->lpszServiceInstanceName != NULL)
wcscpy((TCHAR *)BluetoothQuery_DeviceNameList[BluetoothQuery_DeviceCount],results->lpszServiceInstanceName);
else
wcscpy((TCHAR *)BluetoothQuery_DeviceNameList[BluetoothQuery_DeviceCount],L"<unnamed>");
BluetoothQuery_DeviceCount++;
}
WSALookupServiceEnd(hLookup);
BluetoothClient_Socket = socket (AF_BT, SOCK_STREAM, BTHPROTO_RFCOMM);
if (BluetoothClient_Socket == INVALID_SOCKET)
return false;
SOCKADDR_BTH sa;
memset (&sa, 0, sizeof(sa));
sa.addressFamily = AF_BT;
sa.btAddr = *btaddr;
for (i = 0; i < 30; i++)
{
sa.port = i; //channel & 0xff;
if (connect(BluetoothClient_Socket, (SOCKADDR *) &sa, sizeof(sa)) == 0)
break;
}
if (i >= 30)
{
closesocket(BluetoothClient_Socket);
return false;
}
All calls seems to work out. Sockets are created, all return values look ok. Yet, the client does not connect to the server, so the server never goes beyong that accept() call.
Any comments would be greatly appreciated!
thanks,
Daniel

AT Command to gsm module in WM6

Hello everyone,
This topic is not new however i never see any thread that has the solution for WM6. In my case, i want to create an smartphone app send AT Command to the gsm modem of my HTC HD.
Apparently there's no port COM2 or COM9 open in the device (everytime i tried CreateFile there's error 55, i also checked in the active device registry, no COM2 or COM9), so i use RIL_Initialize and RIL_GetSerialPortHandle to get the port. The openning and writing steps works very well, however there's no data in return, seems that the modem doesn't respond.
Below is the code:
Code:
RIL_Initialize(1,
ResultCallback,
NotifyCallback,
dwNotifications,
dwParam,
&RilHandle);
HANDLE hCom = NULL;
char * xpos;
char rsltstr[5];
DWORD returnValue;
DWORD LAC;
DWORD CellId;
int bufpos;
DCB dcb;
COMMTIMEOUTS to;
DWORD nWritten;
DWORD event1;
DWORD nRead;
char outbuf[20], buf[256];
BYTE comdevcmd[2]= {0x84, 0x00};
GetSerialPortHandleResult = RIL_GetSerialPortHandle(RilHandle,&hCom);
if (FAILED(GetSerialPortHandleResult))
{
TCHAR szString[256];
wsprintf(szString, L"Error GetSerialPortHandle, result= %d",GetSerialPortHandleResult);
MessageBox(NULL, szString, L"Error", MB_OK | MB_ICONERROR);
return 0;
}
if (hCom==NULL || hCom==INVALID_HANDLE_VALUE)
{
TCHAR szBuf[80];
DWORD dw = GetLastError();
// get the most uptodate cells
_stprintf(szBuf, TEXT("CreateFile failed with error %d."), dw);
MessageBox(0, szBuf, TEXT("Error"), MB_OK);
hCom= NULL;
return -1;
}
if (!GetCommState(hCom, &dcb))
{
return -2;
}
dcb.BaudRate= CBR_115200;
dcb.ByteSize= 8;
dcb.fParity= false;
dcb.StopBits= ONESTOPBIT;
if (!SetCommState(hCom, &dcb))
{
return -3;
}
if (!EscapeCommFunction(hCom, SETDTR))
{
return -4;
}
if (!GetCommTimeouts(hCom, &to))
{
return -6;
}
to.ReadIntervalTimeout= 0;
to.ReadTotalTimeoutConstant= 200;
to.ReadTotalTimeoutMultiplier= 0;
to.WriteTotalTimeoutConstant= 20000;
to.WriteTotalTimeoutMultiplier= 0;
if (!SetCommTimeouts(hCom, &to))
{
return -7;
}
if (!SetCommMask(hCom, EV_RXCHAR))
{
return -8;
}
if (!DeviceIoControl (hCom,0xAAAA5679L, comdevcmd,sizeof(comdevcmd),0,0,0,0))
{
TCHAR szBuf[80];
DWORD dw = GetLastError();
// get the most uptodate cells
_stprintf(szBuf, TEXT("DeviceIoControl failed with error %d."), dw);
MessageBox(NULL,szBuf, TEXT("Error"), MB_OK);
return -9;
}
bufpos = 0;
strcpy(outbuf,"AT+creg=2\r");
if (!WriteFile(hCom, outbuf, strlen(outbuf), &nWritten, NULL))
{
return -10;
}
if (nWritten != strlen(outbuf))
{
return -11;
}
/*if (!WaitCommEvent(hCom, &event1, NULL)) // ALWAYS BLOCKED !!!
{
return -12;
}*/Sleep(500);
while(1)
{
if (!ReadFile(hCom, buf+bufpos, 256 - bufpos, &nRead, NULL))
{
return -13;
}
if (nRead == 0) // ALWAYS BREAKS !!!
break;
bufpos += nRead;
if (bufpos >= 256)
break;
}
strcpy(outbuf,"AT+creg?\r");
... // Continue to write and read
As i said above, there's no return error, just that the buffer read is empty...
Any ideas ?
Thanks!

I don't know why it always gets nRead = 0, all the other steps work very well, no error return ...

I saw several discussions about this, so i do believe that someone have tried once this dev in WM5 or 6...
Therefore could anyone please share some point ?

no one has an idea ?

There's something a little bit interesting that i found out directly in the memory.
There's a sequence of responses to AT Command writing in ASCII:
@HTCCSQ:3
@HTCCSQ:4
@HTCCSQ:2
+CREG: 1,"000C","9F60" (here we has current LAC + Cell ID)
+CREG: 1,"000C","9BC7" (another LAC + Cell ID, i think it's the previous one)
+COPS: 0,2,"20820",3 (inside the "" are MCC MNC)
@HTCCSQ:3 .... (there's plenty of @HTCCSQ: coming next )
Look like some kind of log of the querries of RIL driver to the modem (i'm not sure)
So i think the gsm modem is available for answering to the commands, just haven't figured out how to make a stream connection to it (in WM6).
Any ideas ?
Thanks.

TAPI
I heard somewhere that we can use TAPI to send some AT Command, my question is to know if we can send a custom command (for example AT+CCED) by using TAPI ?

hi,I met the same problem.Do you find the answer?
Thanks.

[Q] Selecting Text from a TextView for GingerBread

I would like to select text from a textview,partially that is for Gingerbread as well as higher platforms,I find that android:textIsSelectable is not available and the WebView workaround only does it for complete text,I have tried to use pre-baked code to do this by extending a TextView:

This is followed by:

This is,as expected: clean();
Then this occurs repeatedly:
AndroidRuntime(12712): at com.example.clipboardtest.SelectableTextView$2.onTouch(SelectableTextView.java:120)
which is `lastOnTouch.onTouch(v, event);`
I guess this is because we retain the OnLongClick and OnTouchListener.
Also the code calls for selection of stuff using a background colour and foreground color:
SpannableStringBuilder sb = new SpannableStringBuilder(text);
BackgroundColorSpan bgc = new BackgroundColorSpan(_SelectedBackgroundColor);
ForegroundColorSpan textColor = new ForegroundColorSpan(_SelectedTextColor);
sb.setSpan(bgc, start, end, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
sb.setSpan(textColor, start, end, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
setText(this);
I do not understand why this implementation does not chain to the superclass implementation like I specifically asked it to.Is there anything else I can do,any approach I can follow to make it work,is there a pre-implemented version I can use.If there is nothing can you guide me through implementing a custom TextView for Android

[Q] Threads exits with uncaught exception

Hi, Dear XDA-developers,
Recently, I tried to build an blue tooth app. I wanted to display the data in the screen when all data arrived. I used the following code to do that job. However, the looping between Broadcaster receiver and Handler message could not be linked together smoothly. Usually, after one data displayed, I got an error with the following logs
