Good evening guys,

Looking for any help on interfacing the above GSM/GPRS module with arduino.


VCC and GND of module- separate power supply, 5v 3A

URX to pin 2 UTX to pin 3

Common GND between arduino and separate supply.

Tried AT command code for A6 module, getting +CREG:3 on serial monitor.

Same connections as above with GSM send messages code example on arduino-

Doesn't go past "Sms messages sender

  • what is your question?

  • Is there a way to interface the ga6 module with arduino. I saw some posts say you must flash the module to A6
