So I got the cellular module to work with the M2. I’m able to send myself SMS messages to toggle the LED’s on the M2, send AT commands to the modem (and have it reply the response via SMS), as well as, sending CANBUS messages to my truck. I’ve only reverse engineered one code so far and that was to remote start my truck. If anyone has been working on RAM 1500’s, let me know. Mine’s a 2015.
ANYWAY, now that I got this working I was going to share, however I’m very new to Arduino and it’s been years since I’ve done C++, so I’m wondering if you guys have any code standards to ensure portability with anything I share.
