Hi
I have two gprs modem.One of them is connected to PC,and the other is connected to microcontroller.I want to send data to each other using GPRS.I guess one of them must be master and the another one slave.
AT +CGDCONT=1, "IP", "slave","121.112.113.110",0,0
AT +CGATT=1
AT +CGACT=1,1
ATD*99***1#
Are these at commands used for connecting slave modem which has IP adress 121.112.113.110
