前言 在了解了基础的蓝牙相关概念后,接下来通过学习其GATT Server的例程,了解其如何通过蓝牙注册GATT服务来收发数据。 GATT Server例程解析 图中可以看出,官方的例程当中,gatt_server和gatt_server_service_table两个例程都是用于GATT服务器创建
1.ESP32开启GATT Server 功能,发送带有特定adv data的广播。你可以自定义该广播,该广播不属于 BluFi Profile。 2.使用手机APP搜索到该特定广播,手机作为GATT Client连接 ESP32。你可以决定使用哪款手机 APP。 3.GATT连接建立成功后,手机向ESP32发送“协商过程”数据帧(详情见 BluFi 传输格式)。

For start I'm using gatt_security_server example from ESP-IDF and I can't find the way to manually set BLE password, every time ESP generates random six digit password. Is there a way to set manual password and to disable random password generation in gatt_security_server example? Thank ...
