Hmm, lots of questions popping up regarding the cellular modem. Here comes a few:
Is it possible to hook the cellular modem up to a pc with teraterm to get an interactive AT-session with it? And how?
Have anyone experienced with upgrading the firmware on the SIM900 chip?
The built-in IP protocol stuff in the SIM900 chip does not seem to be used anywhere, is there a good reason for that…? (See http://mt-system.ru/sites/default/files/sim900_ip_application_note_v1.03.pdf for details…)
Any pointers appreciated…!
