在 ESP32 IDF 中建立 GATT Server 的步骤如下：1. 初始化 BLE 驱动程序并创建 GATT 应用程序 在初始化 BLE 驱动程序之前，需要配置 BLE 栈。BLE 栈可以通过 esp_bt_controller_mem_release() 函数来释放。使用 esp_bt_controller_init() 函数来初始化 BLE 控制器。使用 esp_bt_controller_enable() 函数来...
本文使用ESP32 IDF官方的 ble_spp_server_demo 示例。在低功耗蓝牙上实现SPP Server，整体可分为两步： 1. 启动 GATT Server； 2. 启动 SPP Server服务。其它是围绕这两步的必要的事件注册等程序。1. 启动 GATT Server 与前一篇文章类似 ：esp_err_t ret; esp_bt_controller_config_t bt_cfg = BT_C...

为了安全连接,必不可少的修改蓝牙的配对方式,提高产品的安全性。安全配置使充当从设备的GATT服务器能够与主设备绑定,并在它们之间建立加密链接。此功能由[蓝牙规范4.2版]定义(https://www.bluetooth.com/specifications/bluetooth-core-specification)并在ESP-IDF BLE堆栈上实现,特别是在安全管理器协议(SMP)API上实现。
学会了添加 characteristic ,还得学会添加 service,本文来学习新增蓝牙服务。 前言 在上一篇文章,我们使用 ESP-IDF 的示例框架,很方便的就添加好了新的特征值(characteristic ),我们说过,就是开发 service 和 characteristic,所以我们还需要学会添加自己的 Service 。
