infinite loop AT Commands

[ionut]

Im using a gsm module quectel M95.

Are there any restrictions in the gsm protocol regarding the fact that I want to send AT commands in an infinite loop?

while(1)

{

send command

wait for reply

send new command

}

I saw that after two-three iterations of the loop, I don't receive response anymore from GSM module.

Hi ,

   Are you check with the baudrate?Send 2 or 3 AT if you receive OK then go for next cheking.Also check for the voltage because sometimes controller and modem are working on different voltages.
