I am sending data continuously to a remote server using sim300 gsm/gprs modem connected to Arduino Uno microcontroller.At the same time I want to check if I have received a sms on the sim card.In the setup function I have configured the modem to gprs mode and executing the AT+CIPSEND continuously to send data in the main loop program. In my interrupt routine which will be called every 1 second I want to check for the sms notification using AT+CNMI command.So is it ok to check for sms notifications while the modem is operating in gprs mode or is there a clash of sms and gprs mode because the interrupt modem is running asynchronously along with the main program.
