实际使用中我们会配置成LONGRANG的通信方式，可以增加通信距离，这边介绍下主从一体例程中配置此方式的方法，程序通过 #define LONGRANG开启 1）app_central.c文件 static void app_central_start_init(uint8_t index) { log_debug("%s@%d\n", __func__, __LINE__); // Prepare the GAPM_ACTIVITY_START_CMD message struct gapm_activity_start_cmd *p_cmd = KE_MSG_ALLOC(GAPM_ACTIVITY_START_CMD, TASK_GAPM, TASK_APP, gapm_activity_start_cmd);
