How do I send data to my server from sim800 / sim900 using MQTT protocol

Question

I have been trying since past few days to connect my sim800 module with Arduino to send data to server.

I have been referencing this library : https://github.com/elementzonline/SIM800_MQTT

However, when run, it simply gets out of the loop after printing 'AT' command only. I have not been able to run more than that using this library. Does anyone have a working code / sample which I can reference?

Answer 1

After short discussion on Thingsboard forum I would like to summarize solution here:

1) We recommend to use TinyGSM library

2) The person who answer this question was able to publish working code on github. Thanks, Abhay!
