I'm currently looking into how to set up a sense network made from ESP32s to track BLE tokens in an area, but I'm stuck at the first step... Getting Bluetooth & device listing to work on the ESP32, as I couldn't find usable documentation about it.
The idea is to gather signal strength info for the token(s) with the sensor network and forward the data through WiFi with MQTT to a central processing unit which in turn will overlay the calculated positions on a map.
Could anyone help me out with getting BT listing to work?
