Adrian Mitevski / Mbed 2 deprecated mDot_LoRa_Sensornode

A multifunctional and modular Firmware for Multitech's mDot based on ARM mBed provides a widerange of functionality for several Sensors such as MAX44009, BME280, MPU9250, SI1143 and uBlox. It allows you to quickly build a Sensornode that measures specific data with its sensors and sends it via LoRaWAN.

Supported Sensors

Idea

The Firmware has some predefined Application Modes running different Tasks(Measurements). Each mode can be used in a different Scenario. Application_Modes define which sensors are used, how often they aquire data and how often the data has to be sent via LoRa. Lets say you just want to measure the Light then you choose an Application_Mode (or define one) that only runs TaskLight for light measurement. As a standard all measurements are taken every second and sent via LoRa but you can change that interval depending on your usage Scenario
