A library to estimate passenger (PAX) count based on Wi-Fi & Bluetooth signals based on the ESP32 chip. This is a library meant to be used for enabling pax-counting in other projects. For an application facilitating pax-counting, see ESP32-Paxcounter. The library was extracted from the ESP32-Paxcounter project to enhance reusability.

Current version: 1.0.0 RC1

A 1.0 should follow shortly, after which API is considered stable.

LIBPAX_ARDUINO
LIBPAX_ESPIDF

To select the supported counting method you may use:

LIBPAX_WIFI 
LIBPAX_BLE

The number of remembered devices is limited to a maximum of 65535, requiring 8 KBytes of RAM.

Examples
