STM32的串口1连接蓝牙模块，手机能够成功配对蓝牙模块。通过串口1来接收手机发来的指令来控制小车，怎么没反应呀？

主程序如下：

int main(void){

u8 t = 0;
USART1_Config(9600);
WM_Init();

while(1){

      t = USART_ReceiveData(USART1);//接收传过来的数据
      switch(t) //对接收到的结果执行相关操作
      {
           case 0: //前进
                Motor_Speed_Control_Left(50);
                Motor_Speed_Control_Right(50);

           break;
           case 1: //前进
            Motor_Speed_Control_Left(50);
            Motor_Speed_Control_Right(50);

break;

       case 2: //后退
        Motor_Speed_Control_Left(-50);
        Motor_Speed_Control_Right(-50);
        break;

       case 3: //左转
        Motor_Speed_Control_Left(-20);
        Motor_Speed_Control_Right(20);
       break;

       case 4: //右转
        Motor_Speed_Control_Left(20);
        Motor_Speed_Control_Right(-20);
       break;

       default:
        Motor_Speed_Control_Left(0);
        Motor_Speed_Control_Right(0);
       break;
      }//switch

}//while

}
