I have been following your blog, YouTube channel for a quite a long time.
I have worked with Sim 900 module, just wanted to upgrade to 800c so bought one.
But found some practical difficulties while working with it.
I am unable to use AT commands in terminal (TMFT 2.6).
Terminal does not respond to AT Commands… The data bytes are sent, yet Rx is zero.
Have given 5v supply to Sim800c from Arduino, Network led blinks…
Have also tried using Arduino using Tx and Rx pins, but there is no response
Bro please help…
Thanks and Regards
