上一篇介绍使用STM32CubeMX创建的蓝牙应用的代码分布。其中Core和STM32_WPAN/App文件夹中代码需要用户添加自定义的代码来完成具体的应用。这里以示例工程中的BLE_p2pServer的移植为例。
1、添加示例文件
将示例BLE_p2pServer中的app_bsp.c/h文件复制到工程的STM32_WPAN/App文件夹中
https://github.com/STMicroelectronics/STM32CubeWBA/blob/main/Projects/NUCLEO-WBA65RI/Applications/BLE/BLE_p2pServer/STM32_WPAN/App/app_bsp.c
工程添加文件后的效果如下
2、添加应用代码
参考ST MCU Wiki中的代码修改指南，在工程中添加应用代码。
https://wiki.st.com/stm32mcu/wiki/Connectivity:STM32WBA_BLE_STM32CubeMX#Code_modification-_user_sections
修改代码文件在Core文件夹和STM32_WPAN/App文件夹中
参考指南中示例添加代码时，从USE CODE BEGIN XXXX和USE CODE END XXXX来确定代码的添加位置。
在Core/Inc/app_conf.h文件中添加以下
/* USER CODE BEGIN Defines */
/**

#if CFG_LED_SUPPORTED
#undef CFG_LED_SUPPORTED
#define CFG_LED_SUPPORTED (0)
#endif /* CFG_LED_SUPPORTED */
#endif /* CFG_LPM_LEVEL */
/* USER CODE END Defines */
Core/Src/main.c中添加
/* USER CODE BEGIN RNG_Init 2 */
/* Disable RNG peripheral and its RCC clock */
HW_RNG_Disable( );
/* USER CODE END RNG_Init 2 */
Core/Src/stm32wbaxx_it.c:中添加
/* USER CODE BEGIN Includes */
#include "app_bsp.h"
/* USER CODE END Includes */

/* USER CODE END EXTI4_IRQn 1 */
}

void EXTI5_IRQHandler(void)
{
/* USER CODE BEGIN EXTI5_IRQn 0 */
/* USER CODE END EXTI5_IRQn 0 */

/* USER CODE BEGIN EXTI5_IRQn 1 */
BSP_PB_IRQHandler(B2);
/* USER CODE END EXTI5_IRQn 1 */
}

void EXTI13_IRQHandler(void)
{
/* USER CODE BEGIN EXTI13_IRQn 0 */
/* USER CODE END EXTI13_IRQn 0 */
HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_13);
/* USER CODE BEGIN EXTI13_IRQn 1 */
BSP_PB_IRQHandler(B1);
/* USER CODE END EXTI13_IRQn 1 */
}
Core/Inc/app_entry.h中添加
/* USER CODE BEGIN EC */

3、编译和下载、
修改工程配置中的Linker设置添加-z noexecstack标志位
编程成功并下载后，通过ST BLE Toolbox控制开发板上LED灯的效果如下
4、总结
参考官方的移植指南，在NUCELO-WBA65RI上完成BLE-p2p-Server的例程，作为开发蓝牙应用的参考。
