Unstable AT-command replies from GSM-radio

I'm programming on a program that uses cell broadcast messages to determine your position. (http://gknavigation.de) - It was a project at "youth research" this year.
It is based on an idea of W.Back...
Now I want to get rid of a external gsm phone at the position determination, because the new Pocket PC Phone Edition have a integrated radio functionality.
I've written a small terminal-prog. for the XDA (http://gknavigation.de/beta.htm), which let's you sent modem-command into the gsm and recieve replies.
On the XDA2 it is working well until the line "AT command interpreter ready" is displayed on the terminal. After that common AT-commands like "AT+CBC" won't work any longer, and result with an "ERROR".
The line (and the errors as result) seems to apear after a few seconds the port is open.
I think I have opened the port and initialized the shared use of the gsm serial communication well. :?
Check out that Sourcecode please:
The .DLL-file-project, which is written in C++ and opens/closes the port:

The visual basic project, which is for reading and writing operations, and user interface:

Summary
Hi,
Just wanted to let you know that I will have alook and see what I can do
for you.
Have you got a break down of what you are trying to achieve
Click to expand...
Click to collapse
A summ ups are written in German, sorry!
But i will try to describe it briefly:
My prog recieves the messages of the cell broadcast channel 221 by a mobile
phone connected via any inteface. (Bluetooth, IrDA, RS-232)
In Germany this channel contents data about the position and sending
direction of the mobile (fix installed) stations. With some (or many) tricks
i'm able to determinate your own own position up to a 50 meters. (in best
case - depending on the number of installed stations)
This is drawn on a map.
The prog is running under PPC and PC, but the PC version is less
interesting, because the PPC is more portable.
Newerdays, the PPCs have a integrated GSM radio module, so that it should be
possible to recieve those CB-messages vie the internal modem.
By that the users of XDA/MDA/... in Germany would get an alternative to GPS
for navigation/orientation without buying new hardware!
Lateron this prog is perhaps compatible with Tomtom. - I'm checking how to
do it!
Greeting, and thanks in advance!
Florian

hey xda internal access
Hey man i must say i respect you , you have done great work !!!
I am currently working on xda2 as university project and i need to access internal modem of xda ... so might need ur help ... i would wanna help u too and i probly will ... just letting u know i'll try a bit on ur prob and get back to ya ...
any advice ou can give me to access the internal modem ??
great job ! talk soon

On the XDA2 it is working well until the line "AT command interpreter ready" is displayed on the terminal. After that common AT-commands like "AT+CBC" won't work any longer, and result with an "ERROR". Crying or Very sad
The line (and the errors as result) seems to apear after a few seconds the port is open.
I think I have opened the port and initialized the shared use of the gsm serial communication well. Confused
Check out that Sourcecode please:

after read your source, i think:
- set Sleep time between each other AT commands > 100ms for response time of GSM modem
- try to close the com port and re-open it before sending another AT-command.
- try to use only RIL port or COM2, don't open them and use them at the same time.

hey i read through the code its good but i dont see how u get "AT Interpreter Ready" in the VB app ... i looked hard !!! can anyone enlighten me ??

I guess "AT Interpreter Ready" is the answer from device.

AT Interpreter Ready is sent by device after radio resets itself. You should never see this reply.

ok - when i get "AT interpreter Ready" from my terminal it allows me to send an AT commands, so in a way i'm guessing that i should get it -
Indeed it happens when the GSM resets does anyone have more explanations on how it appears ???

i get "AT interpreter Ready", too.

Compile
Could someone compile the DLL and EXE and post them here in one zip? Would save me having to install Visual Studio !

GSM Triplets / RUN GSM ALGORITHM

I need the GSM Triplets for a project but haven't really got a clue how to get them. I tried with RIL_SendSimCmd but I don't know how to write the command nor how to read the answer. Unfortunately I didn't find some useful docs yet.
Does someone know more about this?

An idea? Anybody?
I think I know how to send the command now (see http://ftp.rz.tu-bs.de/pub/mirror/ccc_Chaos_Computer_Club/ftp.ccc.de/gsm/gsm_log_commented for an example), but I still get no answer at all, and my callback function isn't being used at all.
Is there noone who can help me getting this SRES and Kc?

I don't think it is possible, at least with my HTC Blueangel.
The required AT+CSIM (Generic SIMUICC access) command is missing in the command set.
There is only a AT+CRSM (Restricted SIMUICC access) command which only allows access to the SIMs filesystem.

Does this only mean that it won't work with AT commands or does it also mean that it will not work with RIL or even not at all?

AFAIK RIL uses AT commands to communicate with the gsm modem.

Just for completion: I checked with HTC and they say it's impossible with all their devices at this moment.

Engineering Mode

Hey I just found this while browsing my registry on the 8125. It looks interesting but I can't risk having to hard reset right now. I just have too much going on to have to redo my phone at the moment. If anyone can please check it out.
Engineering Mode
Code:
[HKEY_LOCAL_MACHINE\Software\HTC\EngineerMode]
"BuildInEngineeringModeApp"=dword:00000001
"LaunchEngineerModeAppDialStr"="*#*#364#*#*"
Try dialing this in the phone *#*#364#*#*
Please post any findings.
Later; Lew

"....please dial 611 for customer assistance...."

Thats all that happens?

You have to turn it on first (its shut off.) Edit the "BuildInEng..." key to "1" and reboot (soft reset)
I've tried this on the SDA with no results. On the MDA it comes up but all data is blank! If we can figure out WHY (perhaps RAPI locking or something?) we might be able to make that work!

unfortunately it seems to work like that on every htc wizard, not depending on ROM version. i guess this app needs some special library which is not included in 'standard' versions of device aimed on regular consumers but only for network operators etc (like netmonitor in nokia mobiles).

No need to add the registry hust simply type "*#*#364#*#*" without quotes on the phone dial screen it will automatically run the app.

Works on the new IMATE and Qtek roms, but has no data on the earlier ones......

if you change HKEY_LOCAL_MACHINE\Software\HTC\EngineerMode\LaunchEngineerModeAppDialStr value to - for example - *789#, then you can access engineer app via *789# code. much easier and quicker.

Works on Palm Treo Pro out of the box !!!

HTC TyTN FieldTest application [Engineering / Monitor Mode]

Watch out for this link:
http://forum.xda-developers.com/viewtopic.php?t=59464
So finally it's available now.
However on my TyTN only values for RSSI (field strength) and RXqual are showing up.
I'm sure we will be able to fix that with the help of this kind guy, who shared this application with us [I hope he is responding].
Assumably some registry keys have to be set to invoke display of all parameters.

updated the wiki so this reaches more people and hopefully someone can help.

Hi,
I have doopod 838pro, i was trying to connect it with the QPST/QXDM (qualcom diagnostic software installed on leptop) but i cannot as the phone is detected as HTC Modem and not as dignostic COM port. Do you know if there is any driver/software/command for open the dignostic port for detect it as COM on the device manager?Any idea or other solution?
Thanks a lot,

Hi,
Im not sure you'll be able to do that.
The Qualcomm's MSM chipset on the Hermes handle the radio while the applications handled by a different processor (Samsung), unlike what is happening on feature phones.
The data-com connector is controlled by the application processor so no Q's communication is available :-(
Happy new year from the Holyland.

Thank Dukas,
Happy new year to you!
If you have any idea let me know.....thanks a lot,

HOWEVER, TomTom came yesterday with some kind of help in that matter. when TomTom asks you to configure external GPS receiver, it also lists all available COM ports. guess what - one of the ports was described as 'RIL on COM6:' - ha! i'm guessing, RIL is accessible through that port, but usual AT commands don't work, so there must be some other way of doing it...

Try these two drivers. tell me the results

Thank you, i will try it and let you know!

thanks, but.. what exactly am i supposed to do with these files? :-o

It will enable the QPST/QXDM (qualcom diagnostic software) to talk to hermes
This software can extract tons of info from the qualcomm chipset

mhmm ok, but *just* these drivers will not give us that tons. i mean, what also we need is that diagnostic software, right?

this is a reply to rfmanganaro who was asking how to connect QXDM to Hermes

Any idea how to connect QPST to Hermes?

Thanks austin,
I am having some problems on the drivers installation you provided (i don`t know how and where install those) Can you help me?
Drivers for mobile or laptop?
How and where should i install it?
Sorry to disturb you again and Really thanks a lot,

You can buy the software from Qualcomm, this software is used for Radio network optimization and mobile test/debugs, not sure if it is available somewhere in the web.To this software you can connect any qualcomm chipset mobile and monitor all L1,l2 and L3messages, record, show and record radio measurements for HSDPA,R99 and off course connect true GPS for g data collection.Is something similar (but much more complete than the TEMS, COUEI, NETMIZER, NEMO.....)

But how do we install the drivers?
The files posted contain SYS files.
These are sys files but the Modem in the Hermes has its own driver already.
If you try to do an 'update driver' and point to a directory with these sys files in it, they don't work.
I think you also need a .inf file to go with these, or alternatively, mabe there is something needed in the Hermes to start up the modem in a different way.
Any ideas?

Hi irvis, austin,
I tryied but it doesn`t work by updtae HTC modem driver (the .inf file is requested).
Austin, can you provide the .inf file or any other idea of how to install it?
i am sure is possible,
Thanks a lot!

TyTN cellid?

Hi. I am writing a freeware social networking application based on location services ( http://www.fightersoft.ro/mts/index.htm ). Although many devices are supported, it seems that the HTC TyTN isn't. To that end I acquired one and now I am on the quest on getting the cellid in my application.
The approach that should of worked was the COM port. However, no matter what COM port I open, I get a create file error. I am guessing that maybe the internal modem uses a weird port name such as COM550 or other letters instead of COM. I know that another way of getting the cellid is by using ril.dll (or even getting the handle to the gsm modem com port). However, in WM5 this is not documented at all on msdn.com - BUT for WM6 there is documentation.
Firstly, I want to ask anyone if they have extra information about this issue and secondly if by upgrading to WM6, the using the COM port approach works from the box (usually COM9)?

hi, I tryed many programs, which have actually support for cellid information, but no one work on herm, no matter if it was WM5 or WM6. on all phones, I had before it worked correctly... phone alarm also have this functionality, but shown only something like 00-00...

This is so frustrating. Every mobile device with GSM capabilities has a GSM modem insinde. That modem SHOULD be accesible from the OS by the means of COM ports. My guess is that this port is hidden or under a different name than the rest of the HTC devices where it resides on COM9.

CommMgrPro shows Cell Id and Location Area Code correctly on TyNT

I started this thread in the hopes that people will contribute with ideas towards getting this task done. Can you reveal any technical information on how you get the cellid information?

Sure. Ril.dll gives you access to this information and works properly in WM5-WM6. And technically is easier than manager serial drivers......
Documentation isnt included in WM5 so it isnt "official" but realky It is included. The only problem for "not official" issue is you wont get support from microsoft....
Ask me what you want...

stargatesg1, if you have searched the forum, you'd already have the answer. For instance, this thread:
http://forum.xda-developers.com/showthread.php?t=280476&highlight=cellid
has a reference to RIL API. And I do remember I told you this some months ago in your another thread...
Here it is:
http://forum.xda-developers.com/showpost.php?p=1040464&postcount=27
It was at October 26 last year!

Basically I only need the cellid and the lac. I found that msdn.com offers documentation for ril.dll for WM6. This also works for WM5?
From what I learned from msdn.com is that I should do a ril.initialize first and then I should get the cell info using a fuction that I can't remember right now. Is this approach correct?
Lurker0, I know about this approach (I have mentioned it in my first post) however, I need more information because c++ native is not my primary envoirement for developing. That's why I kept searching for a way of getting the lac-cid from com ports so that I could do it directly from managed code.

Exactly. I downloaded Platform builder to have includes and libraries.
1) Initialize Ril
2.a) Request Position explicitally using a RIL_gettowerinfo
2.b) When you initializa Ril you can pass a callback to be notified upon location changes....

Did you read the source code for RIL interface that I pointed you to?

danielherrero, I see. Regarding the callback function is not neccessary in my app - the user or the app set on auto mode searches for changes in location. Thank you very much for your info.
Lurker0, yes I did, but like I said, I am not a very experienced c++ programmer and I need some documentation to get me started. I am also very greatful for your help and I am sure that I will use information from rilclass.cpp.
Thank you both, I will post back with the results as soon as I will have any.

Good luck

Hi StargateSG,
Did you succeeded in getting MTS working on Tytn?
Rgds

I had to leave the country on a business trip. I'll get back in a few days and I will start working on the problem.
