Bluetooth: Peripheral_sc_general
概述
本示例演示了使能 BLE 外围设备角色，和 Peripheral general 示例不同的是, 本示例支持加密流程。 在连接建立后，用户可以在控制台下输入相关的指令以完成配对流程，比如发起安全流程、设置 IO 能力和根据提示，输入配对码。
#define BT_UUID_SERVICE 0xFFF0
#define BT_UUID_CHAR_READ_WRITE 0xFFF1
#define BT_UUID_CHAR_INDCIATE 0xFFF2
#define BT_UUID_CHAR_NOTIFY 0xFFF3
配对指令 (cli commands)
- security:
发起配对流程.
- auth_method:
设置设备输入输出能力，支持display, display and yes/no, input, no-input-no-output, display and input.
- auth_passkey:
给对方设备回复配对码.
- auth_cancel:
取消配对流程.
- auth_passkey_confirm:
确认配对码正确.
- auth_pairing_confirm
确认配对流程.
