Hi
I don't know what happened. I used to use mysim900 normally. I left it for a while and started playing with it again recently.
I receive the startup sequence 00 bla bla bla bla xFF xFF xFF xFF
But I never receive the "ok" or "rdy"
So I can't do anything with the module!

some modules don't have any setting other than AT commands to set baud rate, while initializing with 'AT' followed by 0xD 0xA it will adjust with the baud rate
