1、作用
BLE server(Bluetooth device)的广播数据,client(手机App)可以根据该广播数据进行筛选,例如是否在app的兼容的设备中(只允许指定设备类型显示在已发现的列表中)。
2、举例
以Zound为例。
2.1 广播包数据格式
包含6部分:
1: Manufacturer ID. Value shall always be 0x065A (Zound Industries International AB)---2 bytes,stored as a 16-bit unsigned integer using little endian
2: Device Type. Above shows for adidas RPT-02---1 byte
3: Color (0x00= P1: First Perpetual color (default color))----1 byte
4: Device MAC address (unique for every unit)----6 bytes
5: Pairing mode (00=NOT in paring mode, 01=in pairing mode)---1 byte
6: Zound Service, shall always be AA00 (or 0xAA00).---2 bytes
2.2 client端看到的实际效果
NOTE:在Android设备上使用nRF Connect app
