MQTT connection to AWS IoT and Arduino Mega (or maybe ESP32) via SIM800L module.

The device have to implement the aws security certificates (Amazon root CA 1, device certificate and private key) and should be able to publish and subscribe. I need most a portable layer that implements amazon aws IoT secure sockets API with the SIM800L module using the Arduino IDE. I would be able to change the topic and attach a message to the MQTT string in the simplest way possible.

I already have an Arduino sketch working fine on ESP32 using WiFi. So I only need to port that code on Arduino Mega (or ESP8266) and using SIM800L. I can for sure provide my code.

My budget is around 40€.

Skills: Amazon Web Services, C Programming, Arduino, Internet of Things (IoT), C++ Programming
