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.
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.
