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€.
