Hi All,
My first post in this forum.
I have tried to To turn on Sleep mode in SIM900.
1. For AT+CSCLK=2 , I get OK reply, and after 5-7 sec. serial comm. turns off. But current is not reduced and ~50 mA current is drawn still.
2. For AT+CSCLK=1, Serial stops, I pulled DTR pin high, but still its drawing 50mA,
What is exact problem, please help
