AWS IoT core + SIM800L

Question

Hello,
I am working on a project that reads sensor data (connected to ESP8266) and sends this to Aws IOT core. I was able to test this on Wifi and it works seamlessly. Now I need to do the same using a SIM800l to be able to transmit this data to AWS Iot core even in places where there's no wifi (using the GSM sim data).
I could not find reference to any code on this. Any help in this regard would be appreciated.
Thanks.

Hi. Did you use the AWS IoT Device SDK for embedded C on the ESP8266? If so, you need to replace/extend the transport layer below the coreMQTT library to support the module's AT commands. Similar to what's been done here: https://github.com/FreeRTOS/Lab-Project-FreeRTOS-Cellular-Demo
