Sensirion Gadget BLE Lib

This library enables you to create your own Do-It-Yourself BLE enabled sensor gadget on the ESP32 platform.

Live sensor value broadcasting without requiring a BLE connection
Simultaneous monitoring of sensor data from multiple BLE clients
Sensirion MyAmbience CO2 App compatibility - allows you to monitor your gadgets, plot the sensor values and share/export the data.
Buffering of sensor data for later download (sensor history download)

Please see the examples provided as reference on how to use this library.

Important points to keep in mind:

writeXX writes the corresponding sensor values to the library. But the values are not published to the BLE stack until commit has been called
Keep the loop delay at 3ms, to allow the library to provide history data to the smart phone applications and other BLE clients nearby. Increasing this delay will slow down the download process.
To allow history data downloads, you need to have the handleEvents function within the loop.

This project was developed and tested on Espressif ESP32 DevKitC hardware (see e.g. ESP32-DevKitC-32D)

Download the Sensirion MyAmbience CO2 App to monitor your gadget, plot the sensor values and share/export the data:
