Dear Arduino User Group,
I have a project in hand to control AC motors and servo motors. The customer has asked me to upgrade the firmware of the arduino using 3G/GSM. Can anybody suggest a suitable module to connect the Arduino board with 3G/GSM which can assist me to upgrade the microcontroller program using 3G/GSM/IOT?
So, please suggest the suitable arduino board, suitable 3G/GSM module so that the firmware can be upgraded by sending programming files over internet/3G?
regards,
Nagendra
