CH573 CH582 CH579 peripheral通用外設例子講解三 修改廣播包

void Peripheral_Init()
{
    Peripheral_TaskID = TMOS_ProcessEventRegister(Peripheral_ProcessEvent);

    // Setup the GAP Peripheral Role Profile
    {
        uint8_t  initial_advertising_enable = TRUE;
        uint16_t desired_min_interval = DEFAULT_DESIRED_MIN_CONN_INTERVAL;
        uint16_t desired_max_interval = DEFAULT_DESIRED_MAX_CONN_INTERVAL;

        // Set the GAP Role Parameters
        GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, sizeof(uint8_t), &initial_advertising_enable);//開啟廣播使能
        GAPRole_SetParameter(GAPROLE_SCAN_RSP_DATA, sizeof(scanRspData), scanRspData);//設置掃描應答包
        GAPRole_SetParameter(GAPROLE_ADVERT_DATA, sizeof(advertData), advertData);//設置掃廣播包
        GAPRole_SetParameter(GAPROLE_MIN_CONN_INTERVAL, sizeof(uint16_t), &desired_min_interval);
        GAPRole_SetParameter(GAPROLE_MAX_CONN_INTERVAL, sizeof(uint16_t), &desired_max_interval);//設置預期的連接間隔
    }

如果需要修改廣播包，需要先把廣播關閉

       uint8_t  initial_advertising_enable = FALSE;

            // Set the GAP Role Parameters
            GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, sizeof(uint8_t), &initial_advertising_enable);//關閉廣播包

修改廣播數據

            advertData[5]=advertData[5]+1; //示例，修改廣播數據，
            GAPRole_SetParameter(GAPROLE_SCAN_RSP_DATA, sizeof(scanRspData), scanRspData);//重新設置掃描應答包
            GAPRole_SetParameter(GAPROLE_ADVERT_DATA, sizeof(advertData), advertData);//重新設置廣播包

重新使能廣播

            uint8_t  initial_advertising_enable = TRUE;

            // Set the GAP Role Parameters
            GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, sizeof(uint8_t), &initial_advertising_enable);//使能廣播

測試效果

程序運行，可以看廣播開啟廣播引起的狀態變化 static void peripheralStateNotificationCB(gapRole_States_t newState, gapRoleEvent_t *pEvent)

抓包看廣播包信息，修改位置是變化的

 

 

直接動態修改廣播包和掃描應答包（不用關閉廣播，可以直接調用下面這個函數修改廣播和掃描應答包）

/*******************************************************************************

 *

 *

 */
extern bStatus_t GAP_UpdateAdvertisingData( u8 taskID,u8 adType,u8 dataLen,u8 *pAdvertData );

 

 

直接修改，不用開關廣播，提供的接口

/**
* @brief Setup or change advertising and scan response data.
*
* @note if the return status from this function is SUCCESS,the task isn't complete
* until the GAP_ADV_DATA_UPDATE_DONE_EVENT is sent to the calling application task.

*/
extern bStatus_t GAP_UpdateAdvertisingData( uint8_t taskID, uint8_t adType, uint16_t dataLen, uint8_t *pAdvertData );

例如：
GAP_UpdateAdvertisingData( 0,TRUE ,sizeof( advertData ),advertData );         //  廣播包

GAP_UpdateAdvertisingData( 0,FALSE ,sizeof( scanRspData ),scanRspData );  //   掃描應答包
