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.

For using the library please refer to libpax_api.h. All functions outside the libpax_api.h are considered internal and might change between releases.

You must define one of the following compile time constants to select the framework you are working with:

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.

The /examples folder contains an

The library contains unit tests, which can be run via:

pio test -e espidf -e arduino

Please note: The tests are executed on an esp32 which must be connected via USB.

Please refer to our separate CHANGELOG.md file for differences between releases.
