A BLE scanner application for ESP32 that publishes all detected BLE devices using MQTT.
The ultimate goal of the project is server-side indoor positioning using multiple ESP32 devices that detect beacons.
NOTE: This is work in progress.
NOTE: You need a recent version of ESP-IDF from the master branch of https://github.com/espressif/esp-idf. The latest released version (2.1) is not supported.
