Getting IP address for GPRS

[daniel]

Hi,

I have successfully set up yateBTS using bladerf but i have a small problem.

My phone can connect to the GSM network. Calls and SMS works fine.
For GPRS, it's kind of random. Sometimes a IP Address is issued while sometimes it's not.
I can see my phone being registered when i use the command "mbts gprs list".
Anyway to fix it? What other information do you need?

Best regards,
Daniel C

Hi,

Please specify:
* what version of YateBTS are you using.
* how is it configured
* how are you testing (how close is the phone to the base station, what are the power levels)

Also, please provide a log with GPRS debug enabled.  Check ybts.conf.sample about how to enable that.  Debug should at leeast be enabled on the following files: MAC, TBF, RLCEngine,  LLC, FEC, SGSN. Also check this for more information: http://wiki.yatebts.com/index.php/Logging_and_Debugging

In rmanager, issue command "mbts gprs list" and look at the RSSI level for the phone. If it's positive, you are probably keeping the phone too close to the base station and saturating the receiver (meaning a lot of bursts will be dropped).
Post the result of that command here.
Also post the result of the 'mbts power' command.
Also, please provide a log as specified before.
