Kindly assist
I have been trying to connect Arduino Mega 2560 with M590E GSM Module , But the Module is not responding , could it be a wiring prob?
anyone with a schematic for M590E connectivity with Arduino Mega 2560 Not Arduino Uno .
Have you USB to RS232 adapter to check your M590E module with AT commands? Also give your code for this project.
P.S. As I see from your photo, RX on Mega board seems to be connected to RX at M590E GSM Module. The same for TX line. It should be connected as RX- TX and TX-RX.
