Arduino project to provide PT1000 temperature readings over Bluetooth Low Energy. Using an ESP32-C3-DevKitM-1 and the Adafruit MAX31865.
The firmware advertises a BLE service with UUID 621ABF0E-E642-40D8-B766-8D910900B1C5 containing characteristic E33E3DC8-BCB7-476A-8D26-1B6D968F615C which supports read and notify.
This characteristic provides the measured temperature in °C and the time since boot in seconds in the format ${time} ${temp} encoded as ASCII.
The data can be easily logged with the included script.
