Hi Folk,
I am using RTL-SDR to take dump of cell tower located in my region. Till now,I am able to take GSM incoming call dump which is working perfectly OK. Now, , my goal is to analyze GPRS connection initiation (GPRS attach) and corresponding signaling data. I have tried the scenario by switching OFF and then ON the mobile data but I couldn't see any packets related to GPRS. Is there something I am missing?
