Detailed Description

"ACwing telemetry" GATT service on the STM32WB BLE stack (STM32_WPAN).

Service 7E4A0001-2C6B-4F8E-9A5D-3B1C0E1D2F30 TLM 7E4A0002-... Notify telemetry byte stream (same frames as UART) CMD 7E4A0003-... Write w/o resp. commands (tlm_ble.h: TLM_BLE_CMD_*)

Three hooks go into the CubeMX-generated STM32_WPAN/App/app_ble.c (USER CODE sections, they survive regeneration):

APP_BLE_Init() USER CODE BEGIN APP_BLE_Init_3 ble_tlm_svc_init(); SVCCTL_App_Notification() USER CODE BEGIN HCI_EVT_LE_CONN_COMPLETE ble_tlm_on_connect(p_connection_complete_event->Connection_Handle); USER CODE BEGIN EVT_DISCONN_COMPLETE ble_tlm_on_disconnect();

plus #include "ble_tlm_svc.h" in USER CODE BEGIN Includes. With APP_TLM_BLE = 0 the functions exist but do nothing.
