3.主要用户应用代码
3.1.传感器数据结构体
typedef struct { uint16_t SensorA; uint16_t SensorB; uint16_t SensorC; uint16_t SensorD; uint16_t SensorE; uint16_t SensorF; uint16_t SensorG; }Sensor_Data_t;
3.2.配置广播间隔
1#include “user_config.h” 中 /// Minimum interval for advertising .intv_min MS_TO_BLESLOTS(200), // 200ms
/// Maximum interval for advertising
.intv_max MS_TO_BLESLOTS(200), // 200ms2配置设备名称#define USER_DEVICE_NAME “Sensor” 配置公司ID #define USER_COMPANY_ID 0xFFC1
3.3.主要用户代码说明
3.3.1.主要函数接口
函数接口 说明 user_app_adv_undirect_complete() 广播完成回调函数 user_app_on_db_init_complete() BLE数据库初始化完成回调函数 user_app_adv_start() 开启广播函数 user_app_adv_stop() 关闭广播函数 app_easy_gap_undirected_advertise_start_create_msg 广播数据接口 user_RsfreshSensorData() 传感器数据刷新 user_app_before_sleep() 睡眠前回调函数 user_app_resume_from_sleep() 唤醒时回调函数
3.3.2.打印MAC地址
#if defined (DA14531) extern struct bd_addr dev_bdaddr; uint8_t bd_address[6] CFG_NVDS_TAG_BD_ADDRESS;
arch_printf(OTP addr: %02x %02x %02x %02x %02x %02x\r\n,dev_bdaddr.addr[0],dev_bdaddr.addr[1],dev_bdaddr.addr[2],dev_bdaddr.addr[3],dev_bdaddr.addr[4],dev_bdaddr.addr[5]);arch_printf(nvds addr: %02x %02x %02x %02x %02x %02x\r\n,bd_address[0],bd_address[1],bd_address[2],bd_address[3],bd_address[4],bd_address[5]);#endif arch_printf(“main_loop\r\n”);
