Hai friends,
I am working on a GSM modem, which is SIM 300 command supported.
Everything was working fine, like I can send SMS, send data through gprs, etc.
At first, when I turn the modem to ON position, I am cancelling the echo from the command using ATE0.
But sometimes, after handling with gprs commands, my modem responds with the echo characters also.
This occurs, often when the modem gives a +PDP DEACT response. Unfortunately, I am not saving the current configuration of modem. My doubt is that, will the modem configuration changes without restarting the modem?
Also, usually the modem give responses as soon as it gets the command. But what is the maximum delay that the modem takes for a response?
Please help me.....
