service

A group of related BLE data items, like an environmental sensing service.

A GATT service groups related characteristics under one UUID; standard services have 16-bit UUIDs assigned by the Bluetooth SIG.

Examples

  • Environmental Sensing, 0x181A, is the standard service that groups the sensor's temperature and humidity.

  • The sensor's fan control lives in a custom service named cd681706-bf1b-4e51-be94-aaf6bad0b123.
