[android-porting] Re: GSM on Gingerbread-2.3.4
HI Venkat, Thank for your suggestions on GSM. Am using gobi 3000 in my device to the GSM module. when i try to enable Gobiserial and Gobinet drivers. its showing only GobiSerial and able to establish a call. if i disable GObiSerial then GobiNet is enabling but not detecting GSM module. Can you help to enable both the drivers regarding GSM module Will it possible to enable to different class of drivers(serial Net) to this GSM purpose. Thanks, Venkatesh. -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting
Re: [android-porting] Re: GSM on Gingerbread-2.3.4
Hi venky6 babu and babuvenkatesh56, if your modem have two physical ports then there is no problem AFAIK, just see my previous messages in this thread . telephony (rild daemon) pass one port and net connection (pppd) pass other one. but if have only one physical port and you want to integrate two modules then there is conflicting here. i have been trying it too!

[android-porting] Re: GSM on Gingerbread-2.3.4
Does it crash at a different point each time or does it die after the same
request every time?If the usb wasn't getting disconnected, judging by the
random point on crash, i would have said if might be a buffer read error.
But if usb is getting disconnected as well, it might be different problem.

Hi Venkat,
Reset is not necessary. But i don't think it is happening voluntarily. Did
you modify and reduce the log. If not, the things got worse compared to
your last log
herehttps://rowboat.googlegroups.com/attach/bd54dcd92e285509/minicom_radio_usb.txt?view=1part=4.
You didn't get response for AT ATE0Q0V1 . IF you are using 0xdroid
sources, from sources i can say,it died after this function
requestRadioPower.
Your log doesn't show AT+CFUN being sent, so i don't think
it might have caused it. The weird thing is your modem is notifying it's
death. I don't think RIL asked for the modem to die. There might be
something else.
By resetting, do you mean the modem recovers and starts working again {or}
does it stay dead?
But If you are sure AT+CFUN is causing error, then comment out the call
for the requestRadioPower in the onRequest function's switch case
loop of ril sources. That will make the AT+CFUN ineffective from RIL.

Hi Devindrappa,
The log shows none of the scripts are working. correctly. The log is
continued and i can't make out which error is for which script. Could you
please empty the log everytime before running a a script. That way i will
know which error is for which script.
In the attached log i seprated them.
1. The first set is from the old log only.
2. In the second set, it is still expecting AT as response. I don't
know which script is giving this.
3. The 3rd,4th,5th,6th sets almost got it right. They are SENDING
AT^M and expecting OK as result but since it is sending wrong message, it
will not get ok. WORK ON THE SCRIPT GIVING THIS RESULT. give
AT/c instead of just AT and retry.
4. The next few sets are failing because they are expecting /rAT as
a response from modem. the script giving this error needs to be modified
to
have a space between /r and AT. it should be /r AT not /rAT
5. The next few sets have a syntax mistake. Try to put a missing '
[OR] for the script giving this error.
6. The last 3 sets are again expecting /rAT as a response from
modem. Do as i said in step 4.
So basically all scripts are still wrong. That is why we are still
getting same error. Could you please separate which error is for which
script. Tell me which script is giving the error i said in step 3. We have
a improvement but still we didn't get it correctly.

Hi Devindrappa,
1. Please send new ppp-log and go through my previous message.
2. I was right about the REQUEST_GET_PREFERRED_NETWORK_TYPE it is
for 2G/3G only.I checked my huawei ril , i have this in it:-
switch (request){
case RIL_REQUEST_SET_PREFERRED_NETWORK_TYPE:
requestSetPreferredNetworkType(data, datalen, t);
break;
and for the function requestSetPreferredNetworkType i'm giving at
commands at+bandset=0 and AT+CGAATT=2,1,1 which will set my haweui E1732
for gsm only =2,1,2 for 3G only and 2,1,0 for dual mode. You can see in
this forum here forum.xda-developers.com/archive/index.php/t-711753.html.
Search for my said commands and you will find details.
3. . So obviously you don't have to deal with this. But if you still
want to loose the error continue reading. Maybe the cause for error was
your that your RIL didnot define how to handle the request itself. So it is
giving error that request can't be supported by this ril. Look for the
function static void onRequest (int request, void *data, size_t datalen,
RIL_Token t) it will have a switch case statement with request as
switch. In that give a case statement as i mentioned above at start of this
message, but don't mention any function to call.leave it blank. That's it
your error should vanish.
4. If you are keen on working with data connection in RIL. The best the
ril can do for you is give the initialization commands. It cannot setup the
connection, just sends at commands. look for function
requestSetupDataCall this will have the initialization commands to be
sent to modem before pppd link. This is the best the ril can do for you
with respect to a data connection. It canNOT setup a data link. You will
have to call pppd for that. The reason we are not using this yet, is bcoz
we can't edit it frequently like

2. I was right about the REQUEST_GET_PREFERRED_NETWORK_TYPE it is
for 2G/3G only.I checked my huawei ril , i have this in it:-
switch (request){
case RIL_REQUEST_SET_PREFERRED_NETWORK_TYPE:
requestSetPreferredNetworkType(data, datalen, t);
break;
and for the function requestSetPreferredNetworkType i'm giving at
commands at+bandset=0 and AT+CGAATT=2,1,1 which will set my haweui E1732
for gsm only =2,1,2 for 3G only and 2,1,0 for dual mode. You can see in
this forum here forum.xda-developers.com/archive/index.php/t-711753.html.
Search for my said commands and you will find details.
3. . So obviously you don't have to deal with this. But if you still want
to loose the error continue reading. Maybe the cause for error was your
that your RIL didnot define how to handle the request itself. So it is
giving error that request can't be supported by this ril. Look for the
function static void onRequest (int request, void *data, size_t datalen,
RIL_Token t) it will have a switch case statement with request as
switch. In that give a case statement as i mentioned above at start of this
message, but don't mention any function to call.leave it blank. That's it
your error should vanish.
4. If you are keen on working with data connection in RIL. The best the
ril can do for you is give the initialization commands. It cannot setup the
connection, just sends at commands. look for function
requestSetupDataCall this will have the initialization commands to be
sent to modem before pppd link. This is the best the ril can do for you
with respect to a data connection. It canNOT setup a data link. You will
have to call pppd for that. The reason we are not using this yet, is bcoz
we can't edit it frequently like the chat script and we didn't figure out
the correct initialization commands yet and it does the exact same thing
the chat script does for us. If the chat scripts fails this will fail as
well. once we have a working connection we can comeback to the RIL. As i
said ril has very little influence, if not none, in establishing a data
connection. So 1st get data connection, then debug ril coz ril will not
help in data connection in anyway. we can get data connection without ril.
So just concentrate on the pppd logs for the moment. Ignore RIL.
5. And as for the c program to send at commands. Good idea by venkat. but
you can also do it by cross compiling echo if you don't already have it
for ARM. Then you can send any at command by giving command echo
atd*99***1# /dev/ttyS0. You can also use write instead. May be cat
will also work but i never tried it.

Hi Devindrappa,
1.Could you please post new ppp-log. It would have changed for sure.
2.As venkat suggests remove rild startup from init.rc and re run and see
what happens. Comment out the rild service.
3.I will look into the error but ril has very little influence, if not
none, in establishing a data connection. The ril is doing everything it is
supposed to do. It is for telephony services only.
4.I'm not sure but i think the preffered network type has to do with a
AT command which sets whether to look for a 2G or 3G network first {or} the
network scan order to register in the specific network. It sets its order
to scan for networks. It is for 3G modems. I had experience with it when i
was working with a huawei modem. It may not apply in your case because your
modem doesn't support 3G and hence it's AT command is not accepted. I will
look into it and get back to you with confirm answer.
5.IF you think it is a sim lock for the time being you can simply
replace the sim and go ahead. A lock is sim specific. A modem won't report
a lock unless sim states so.

Hi venkat, for running from init.rc simply put your command in a script and add the script as a service.

But if the problem is that you are getting above error log then the problem is that after at+cgdcont=1... your modem is not giving OK response it is giving new line characters and timing out. Did you want it to send a newline character after CellOne ~ *^**M. *if not, then that may be the culprit. Or may be your modem is not able to complete the request before the timeout.

[android-porting] Re: GSM on Gingerbread-2.3.4
Hi Devindrappa,
1.Could you please post new ppp-log. It would have changed for sure.
2.As venkat suggests remove rild startup from init.rc and re run and see
what happens. Comment out the rild service.
3.I will look into the error but ril has very little influence, if not
none, in establishing a data connection. The ril is doing everything it is
supposed to do. It is for telephony services only.
4.I'm not sure but i think the preffered network type has to do with a AT
command which sets whether to look for a 2G or 3G network first {or} the
network scan order to register in the specific network. It sets its order
to scan for networks. It is for 3G modems. I had experience with it when i
was working with a huawei modem. It may not apply in your case because your
modem doesn't support 3G and hence it's AT command is not accepted. I will
look into it and get back to you with confirm answer.
5.IF you think it is a sim lock for the time being you can simply replace
the sim and go ahead. A lock is sim specific. A modem won't report a lock
unless sim states so.

Hi venkat,
for running from init.rc simply put your command in a script and add the
script as a service. You can follow instructions here :-
http://afewe.wordpress.com/android-arm-development/use-point-to-point-protocol-ppp-in-android/
Just modify the non commented /system/bin/pppd /dev/ttyUSB0 115200
mo.. line with your command and add this in your init.rc file
service pppd_gprs /etc/ppp/init.gprs-pppd
user root
group radio cache inet misc
If you run pppd and rild together what error are you getting? if your
modem is getting disconnected then i may not be able to help bcoz i don't
have the same modem. But if the problem is that you are getting above error
log then the problem is that after at+cgdcont=1... your modem is not giving
OK response it is giving new line characters and timing out. Did you want
it to send a newline character after CellOne ~ *^**M. *if not, then
that may be the culprit. Or may be your modem is not able to complete the
request before the timeout.

[android-porting] Re: GSM on Gingerbread-2.3.4
Hi Devindrappa,
1. Please send new ppp-log and go through my previous message.
2. I was right about the REQUEST_GET_PREFERRED_NETWORK_TYPE it is for
2G/3G only.I checked my huawei ril , i have this in it:-
switch (request){
case RIL_REQUEST_SET_PREFERRED_NETWORK_TYPE:
requestSetPreferredNetworkType(data, datalen, t);
break;
and for the function requestSetPreferredNetworkType i'm giving at
commands at+bandset=0 and AT+CGAATT=2,1,1 which will set my haweui E1732
for gsm only =2,1,2 for 3G only and 2,1,0 for dual mode. You can see in
this forum here forum.xda-developers.com/archive/index.php/t-711753.html .
Search for my said commands and you will find details.
3. . So obviously you don't have to deal with this. But if you still want
to loose the error continue reading. Maybe the cause for error was your
that your RIL didnot define how to handle the request itself. So it is
giving error that request can't be supported by this ril. Look for the
function static void onRequest (int request, void *data, size_t datalen,
RIL_Token t) it will have a switch case statement with request as
switch. In that give a case statement as i mentioned above at start of this
message, but don't mention any function to call.leave it blank. That's it
your error should vanish.
4. If you are keen on working with data connection in RIL. The best the
ril can do for you is give the initialization commands. It cannot setup the
connection, just sends at commands. look for function
requestSetupDataCall this will have the initialization commands to be
sent to modem before pppd link. This is the best the ril can do for you
with respect to a data connection. It canNOT setup a data link. You will
have to call pppd for that. The reason we are not using this yet, is bcoz
we can't edit it frequently like the chat script and we didn't figure out
the correct initialization commands yet and it does the exact same thing
the chat script does for us. If the chat scripts fails this will fail as
well. once we have a working connection we can comeback to the RIL. As i
said ril has very little influence, if not none, in establishing a data
connection. So 1st get data connection, then debug ril coz ril will not
help in data connection in anyway. we can get data connection without ril.
So just concentrate on the pppd logs for the moment. Ignore RIL.
5. And as for the c program to send at commands. Good idea by venkat. but
you can also do it by cross compiling echo if you don't already have it
for ARM. Then you can send any at command by giving command echo
atd*99***1# /dev/ttyS0. You can also use write instead. May be cat
will also work but i never tried it.
