direct_adv

功能概述

本示例演示了 BLE 的定向广播功能。在没有 BONDED 的时候，程序发送常规性可连接广播。一旦 BOND 成功，后续每次设备重新启动将发送指向 BONDED 设备的定向广播。除此之外，程序还提供了两种 BLE characteristics：分别支持 BOND 的写操作和不支持 BOND 的读操作。

警告

特别注意 iOS 设备不支持接收定向广播功能，具体信息请参考 “Accessory Design Guidelines for Apple Devices”

环境要求

支持 BLE 功能的开发板
使能 Privacy 特性的中央功能的 BLE 设备。如另外一块支持 BLE 功能的开发板或者智能手机

编译和烧录
