XBee API Bluetooth® Low Energy (LE) Service
You can configure the XBee through the Bluetooth LE interface using API frame requests and responses. The API frame format through Bluetooth is equivalent to setting AP=1 and transmitting the frames over the UART or SPI interface. API frames can be executed over Bluetooth regardless of the AP setting.
The Bluetooth LE interface allows these frames:
- Bluetooth® Low Energy Unlock API - 0x2C
- Bluetooth® Low Energy Unlock Response - 0xAC
- AT Command - 0x08
- User Data Relay - 0x2D
This API reference assumes that you are familiar with Bluetooth and GATT services. The specifications for Bluetooth are an open standard and can be found at the following links:
- Bluetooth Core Specifications: https://www.bluetooth.com/specifications/bluetooth-core-specification
- Bluetooth GATT: https://www.bluetooth.com/specifications/gatt/generic-attributes-overview
The XBee API GATT Service contains two characteristics: the API Request characteristic and the API Response characteristic. The UUIDs for the service and its characteristics are listed in the table below.
| Characteristic | UUID |
|---|---|
| API Service UUID | 53da53b9-0447-425a-b9ea-9837505eb59a |
| API Request Characteristic UUID | 7dddca00-3e05-4651-9254-44074792c590 |
| API Response Characteristic UUID | f9279ee9-2cd0-410c-81cc-adf11e4e5aea |
