查看“︁Demo:smartconfig ble”︁的源代码

== Demo介绍： ==
该Demo使用BLE 蓝牙通讯 技术实现从手机端操控目标设备进行WIFI配网。

该Demo 保存在SDK下的：bouffalo_sdk/examples/wifi/sta/smartconfig_ble 路经下。

其中，手机 APK 放在该目录下的blsync 目录中。

== 主要功能分析 ==

=== 1. BLE 配网与同步 ===

* 通过 BLE 广播和连接，实现手机等设备与目标设备的配对和通信。
* BLE 端通过 <code>blsync_ble_app.c</code> 管理 BLE 广播、连接、数据同步、Wi-Fi 配网等流程。
* 支持 BLE 端发起 Wi-Fi 扫描、连接、断开、状态查询等操作，并通过 BLE 通道将结果回传给上位机或手机。

=== 2. Wi-Fi 智能配网 ===

* 通过 BLE 通道下发 Wi-Fi SSID、密码等信息，设备自动连接到指定的 Wi-Fi 路由器。
* 支持 Wi-Fi 扫描，获取周围可用的 Wi-Fi 列表，并通过 BLE 返回给手机端。
* 支持 Wi-Fi 连接状态、IP 地址、网关、掩码等信息的查询和回传。


另外：<code>payload.c</code>、<code>transfer.c</code>、<code>encrypt_layer.c</code> 等文件实现了 BLE 配网协议的数据封装、分包、加密、解密、校验、ACK 等机制，保证 BLE 通信过程中的数据完整性和安全性。

=== 当配网正确时的输出： ===
