Hi,
We are using EHS5 module and when we are integrating GPRS ril library in android our GPRS-Reset is being called.We wanted to know what is the reason for this reset.
Thankyou,

Hello,
Could you check the RIL version?
Thanks,
Bartłomiej
Cinterion
EHS5-E
REVISION 03.001
Pre-Release_Android_IMC_RIL_1100
A-REVISION 00.000.14
Is there any line need to be commented in RIL library
Ril version is 1.01
IMC_RIL_1100
Hello,
The version is correct. Could you paste the logs that would visualize the problem?
Thanks,
Bartłomiej

Hello,
Thank you for the log.
I can see there that the module is being shut down with AT^SMSO command some time before there's GPRS-Reset and when it's already registered to the network and the profile is activated. And some time later the module is started again. And in the end of the log the module is registered to the network again and the profile is activated.
It seems that the log itself does not answer all questions.
Could you provide some more information? First it would be good to have timestamps in the log (-t). Please provide the Android version and some description about the solution - what's the hardware, what's the scenario, what's going on on the device, do you remove the SIM card during the operation, is the communication finally working according to your ***** after this GPRS-Reset, how often does this GPRS-Reset happen, has the SIM card been tested with other device?
Thanks,
Bartłomiej
We are using android lollipop 5.0.0,This reset happens everytime when our application board is booted once it is android lock screen appears.During this operation we are not removing the sim card.Sometimes because of this reset the ACM0 is not created and it is not registered to network.
Hello,
So for now it looks like the reset is initiated by Android.
Have you already grabbed any more logs with timestamps?

Bartłomiej
No... i will capture and update soon.
