3 years ago Hey Avong,
The Library doesn't support HTTP POST request, but only GET request and that's why the HTTPACTION value is 0. I can't add that at this point in time.
For nonblocking possibility, you have to recode the whole _checkresponse functionality so instead of using the blocking delay, you can track time with millis() and only move to the next state until the target time is reached. You can read more about non-blocking with Arduino using Millis.
All the best, Regards
Ayo, Good job. It took me sleepless nights to understand the SIM800.
However, I have observation in this your BareBone library. Check line 540 in .cpp file.
Under method sendHttpdata. AT COMMAND for HTTP POST should ta value 1 not 0 as you indicated.
I maybe wrong anyway.
Secondly, can you give me idea, I wish to develop nonblock library to be used in rtos. But attempt s seem have not yield anything good.
