CC2530: Using SIM800L with cc2530

Hello guys,

I am working on a cool project that I try to gather a GPRS module (SIM800L) with cc2530. I am running it on top of the TIMAC software and everythiing seems works fine, but just for a certain time.

So, after it sends a couple of messages to my cell phone via the gprs module the microcontroller tends to restart for no reason.

Then, my question:

Is there any amount of code inside TIMAC that forces the microcontroller to restart for any reason?

(If not, I will assume it just lack of power.. eventhough I had taken all precaussion for that)

Thank you!
