In my frustration with the cellular module, I have been beating the bush for alternatives.
We need a cool driver. (period!)
I have found this code by Libelium, which seems to be of pretty high quality. https://github.com/Libelium/waspmoteapi/tree/master/libraries/GPRS_Pro
Would it be feasible to port this, or can it be used as is for non-commercial purposes?
