GATT_Notification（）通知，客户端接收不到数据

新装的BLE-CC254x-1.4.0协议找，使用的SimpleBLEPeripheral工程，直接在simpleBLEPeripheral.c文件中添加函数如下：

static void sendData(void )
{

static uint16 counter=0;
uint8 burstData[20] = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};

burstData[0] = (counter & 0xFF00)>>8;
burstData[1] = (counter & 0xFF);


attHandleValueNoti_t nData;
nData.len = 20;
nData.handle = 20;

//skKeyPressed = *((uint8*)pValue);
osal_memcpy( &nData.value, &burstData, 20 );

// Send the Notification
if (GATT_Notification( 0, &nData, FALSE )==SUCCESS)
{
counter++;
}

if(counter >1000)
{
osal_stop_timerEx(simpleBLEPeripheral_TaskID,SBP_PERIODIC_EVT);
counter = 0;
}

}

周期循环调用该函数，但是主机无法收到数据
