#1

I am working with Quectel’s MC60 GSM module.I have given at commands as input it worked fine after that I changed the baud rate it is returning Junk characters,so I have again changed the baud rate still it is giving me the same result.I have searched many forums can anyone suggest me a solution.

I have worked many times but,I haven’t faced this issue yet.Once try restarting the module and check it is working or not.If it doesn’t work then check the baudrate.And also make sure you are supplying correct voltage to the serial pins .If the voltage exceeds then also they are many cases to damage the pins.
