1. Refer to the latest SDK---W800_SDK_v1. 00. 082. The red box in the screenshot is W800 the READ Stats UUID The callback interface, Here for BLE Data is passed down the stack. 3. This is the structure that configures the callback inlet: I hope it solves your problem.

The above understanding is not sufficient, Update under: 1. tls_ble_server_disconnect function---This function is another set BT stack API. 2. At present SDK The default is nimble Protocol stack, This function does not exist, if

Please refer to this DEMO wm_sdk_w800_20211203srcappbtappwm_ble_server_api_demo. c The principle is BLE The bottom layer of the stack is initialized with the registered callback interface, Returns the handle to the connection
