IoT Mobile App with Realtime remote sensor reading

Lecture de la température en temps réel IoT des capteurs BLE distants sur une application Android Thins

This is a IoT (Internet of Things) Project that uses a commercial SoM (System on module) hardware with additional port, running the Android Things OS and with a custom made hardware attached to it through General Purpose Input Outputs (Gpio).

Sensors are connected over a Bluetootl Low Energy communication with the Android Things Hardware, temperature readings are shown on the three displays and then they are uploaded to the cloud using the MQTT (Message Queuing Telemetry Transport) Protocol.

MQTT Telemetry Data is encrypted using an RSA-256 Key of at 2048bits+ with a Private Key and a Public Key that the server uses to check the origin an Authenticate.

Sensor values are uploaded to the cloud every 5 seconds and data is available in realtime on the mobile client Android App.
