蓝牙看不懂，只能通过串口入手，仿真找到以下函数，串口接收数据，通过蓝牙发送出去

static serialStatus_t Serial_WriteInternal( uint8_t InterfaceId )

#endif
      for( i = 0; i < gSerialManagerMaxInterfaces_c; i++ )
      {
         OSA_InterruptDisable();
         ev = mSerials.events;
         mSerials.events = 0;
         OSA_InterruptEnable();

         if ( (ev & gSMGR_Rx_c) &&
