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
