STM32WBA52CG是支持蓝牙BLE 5.3，官方提供的STM32Cube_FW_WBA_V1.1.0资料包中提供了一个非常好的入门案例：BLE_p2pServer。
准备材料：
Keil, ST BLE Toolbox
图形化配置时钟：
主要的代码包括在主函数中调用aci_gatt_init（）来初始化GATT接口，调用aci_gap_init（）来初始化GAP：
/* Initialize GATT interface */
ret = aci_gatt_init();
if (ret != BLE_STATUS_SUCCESS)
{
APP_DBG_MSG(" Fail : aci_gatt_init command, result: 0x%02X\n", ret);
}
else
{
APP_DBG_MSG(" Success: aci_gatt_init command\n");
}
/* Initialize GAP interface */
role = 0U;
role |= GAP_PERIPHERAL_ROLE;
/* USER CODE BEGIN Role_Mngt*/
/* USER CODE END Role_Mngt */
if (role > 0)
{
ret = aci_gap_init(role,
#if ((CFG_BD_ADDRESS_TYPE == GAP_RESOLVABLE_PRIVATE_ADDR) || (CFG_BD_ADDRESS_TYPE == GAP_NON_RESOLVABLE_PRIVATE_ADDR))
PRIVACY_ENABLED,
#else
PRIVACY_DISABLED,
#endif /* (CFG_BD_ADDRESS_TYPE == GAP_RESOLVABLE_PRIVATE_ADDR) || (CFG_BD_ADDRESS_TYPE == GAP_NON_RESOLVABLE_PRIVATE_ADDR) */
sizeof(a_GapDeviceName),
&gap_service_handle,
&gap_dev_name_char_handle,
&gap_appearance_char_handle);
相关的函数调用栈：
main() -> MX_APPE_Init() -> APP_BLE_Init() -> Ble_Hci_Gap_Gatt_Init()
安卓手机安装ST BLE TOOLBOX V1.3.5，这个版本支持STM32WB系列的新产品例程。
打开ST蓝牙助手，找到例程对应的ST ble设备，即下图的p2pS_00。这里的设备名称与官方文档中的有些差异：- Open ST BLE Toolbox application: select the P2PS_WBAxx in the device list, where xx is the 2 last digits of the BD ADDRESS.
点击Connect后，串口助手输出如下：==>> Start Ble_Hci_Gap_Gatt_Init function

点击LED灯的图标，即可打开或者关闭板子上的LED.
串口助手的输出：
