Micaz节点采集RSSI可用的收发节点代码

经过两周的测试，以下代码可以稳定用于节点的RSSI的收发。以备后用。

发送节点的代码：

includes PongMsg;
//includes Timer;

module SndPongM
{
  provides interface StdControl;
  //uses interface StdControl;
  uses interface Timer;
  uses interface SendMsg;
  //uses interface ReceiveMsg;
 // uses interface ReceiveMsg as PingMsg;
  uses interface Leds;
}
implementation
{
  TOS_Msg m_msg;
  TOS_MsgPtr p_msg;
  PongMsg_t* pongmsg;
  
  command result_t StdControl.init()
  {
    pongmsg = (PongMsg_t*)m_msg.data;
    p_msg = &m_msg;
    call Leds.init();
    return SUCCESS;
  }

  command result_t StdControl.start()
  {
    call Timer.start(TIMER_REPEAT, 200);//注释掉
    return SUCCESS;
  }

  command result_t StdControl.stop()
  {
    return SUCCESS;
  }

  event result_t Timer.fired()
  {   
    //PongMsg_t* pongmsg=(PongMsg_t*)(p_msg->data);
	call Leds.redToggle();
	//call ReceiveMsg.receive( TOS_MsgPtr msg );
	atomic{
        pongmsg->src = TOS_LOCAL_ADDRESS;
        pongmsg->counter=0;
	    pongmsg->dest =TOS_BCAST_ADDR;
        pongmsg->dest_rssi = 0;
        pongmsg->dest_lqi = 0; 
    } 
    if(call SendMsg.send(TOS_BCAST_ADDR, sizeof(pongmsg), p_msg))
	{
       call Leds.yellowToggle();
	}
    return SUCCESS;
  }

  event result_t SendMsg.sendDone( TOS_MsgPtr msg, result_t success )
  {
    return SUCCESS;
  }
}

接收节点接收后，完成计数数据包，并发送给串口：

includes PongMsg;
//includes Timer;

module RcvPongM
{
  provides interface StdControl;
  //uses interface StdControl;
  uses 
  {
   //interface Timer;
   interface SendMsg;
   interface ReceiveMsg;
 // uses interface ReceiveMsg as PingMsg;
   interface Leds;
   }
}
implementation
{
  TOS_Msg m_msg;
  TOS_MsgPtr p_msg;
  PongMsg_t* pongmsg;
  uint16_t datacounter;


  command result_t StdControl.init()
  {
    pongmsg = (PongMsg_t*)m_msg.data;
    p_msg=&m_msg;
	datacounter=0;
    
    call Leds.init();
    return SUCCESS;
  }

  command result_t StdControl.start()
  {
    return SUCCESS;
  }

  command result_t StdControl.stop()
  {
    return SUCCESS;
  }

  event result_t SendMsg.sendDone( TOS_MsgPtr msg, result_t success )
  {
    return SUCCESS;
  }

  event TOS_MsgPtr ReceiveMsg.receive( TOS_MsgPtr msg )
  {
   PongMsg_t* _pongmsg;
   _pongmsg = (PongMsg_t*)msg->data;
   datacounter+=1;
   atomic{
      pongmsg->src = _pongmsg->src;
	  pongmsg->counter = datacounter;
	  pongmsg->dest = TOS_LOCAL_ADDRESS;
      pongmsg->dest_rssi = msg->strength;
      pongmsg->dest_lqi = msg->lqi;
  }
   if(call SendMsg.send(TOS_UART_ADDR,sizeof(PongMsg_t), p_msg)){
   
   call Leds.yellowToggle();
   }
   return msg;
  }
 }

当一发一收的时候，接收节点的接收计数器值为那个节点发送的数据包个数。多发一收时，为收到所有数据包的总和。
