I am using SIM800L module. I am new to GSM modules. I have searched in many web sites about SIM800L, every where they mentioned baud rate 9600 for
SoftwareSerial but it is not working at all in my case. So I started a trail and error method to match baud rate. Finally I found that its baud rate is 38400. With baud rate of 9600 for Arduino and 38400 I am able to communicate with SIM800L.
The problem is that I am unable to register to network.
AT+COPS=? shows all available networks. Using
AT+COPS="value" I am able to select network. But after that the SIM800L module still blinks every second.
loop() I am continuously reading software serial and it's printing the following:
RDY +CFUN: 1 +CPIN: READY Call Ready SMS Ready RDY +CFUN: 1 +CPIN: READY Call Ready SMS Ready
The above data is continuously printing on console.
