My code reads in the M590E GSM Modem via serial communication using interrupt. An array has been created to receive all the value coming into the mcu. My question is how do i do it in a way such that its onlt the massage alone i get to extract from the message content.
I use AT+CNMI = 2,2,0,0,0
this sends the whole message to the serial com directly, i want to kindly tell me how am i could retrieve the message content alone, without the other informations.
Attached is a copy of my project.
