你看下我得操作步骤：
1、用示例工程生成一个ble4.2的server工程
2、在main_app函数中加上show_bonded_devices（）；

3、设置ble地址为固定地址，防止每次都产生一个新的蓝牙记录。
- 2.png (21.36 KiB) Viewed 5013 times
- 3.png (39.5 KiB) Viewed 5013 times
4、然后编译烧写后，第一次打开用手机系统的蓝牙设置连接一下。
5、重启设备，先不用手机连接，观察show_bonded_devices（） 函数的打印信息。

开发环境：ESP IDF 4.4.2 开发板：ESP32-S3-DevKitC-1 v1.1 PC:win11 在编译测试gatt_security_server这个工程的时候，使用BLE4.2.在测试手机连接后，重启ESP32S3，板子上的绑定信息就丢失了。还有我添加到白名单的地址也会随着重启消失。白名单我可以通过NVS记录，但是绑定的密钥信息我无法存储。我查阅了BLE的接口文档，没有看到保存绑定信息的接口。请教一下我应该怎么搞。
我这边使用 esp32s3 开发板测试ESP IDF 4.4.2下的 gatt_security_server 示例没有遇到这个问题； 重启esp32s3, 手机再次与之相连，绑定地址是之前配对手机的，绑定设备数目也是 1 个

在 gatt_security_server 中这个 remove_all_bonded_devices()
https://github.com/espressif/esp-idf/bl ... emo.c#L581 API 是可以删除绑定设备信息的，但是这部分代码是默认屏蔽的
