Hi,
I'm trying to send sms with GSM shield but it's hanging when trying to detected 9600 baud.
GSM shield cannot communicate with arduino.

I've enabled debug mode with GSM gsmAccess(true) and all I can see is AT%13%

I've followed instruction from:

I've searched a lot of topics but I'm not able to find how to fix that.
I'm using Arduino Mega and GSM with SIM808

Any help appreciated

You probably already did this but did you use a jumper wire between pins 2 and 10?
You also need to bend the pin on the shield to prevent it from connecting with pin 2 of the Mega. Did you bend this pin out of the way?

yes I have already done that.

I have found some documentation SIM808 GPRS/GSM+GPS Shield v1.1 - Elecrow
but still nothing helped :confused:
