and in TOSBaseM.nc, I went through the code in line 107 which is used to send TOS_MSG via radio, the code is:
      Result = call RadioSend.send(gpTxMsg);  //  TOS_MsgPtr gpTxMsg;
   
  and it is very interesting if you look through the implementation of RadioSend.send in CRCPacket.nc,  the send function only send the first byte of gpTxMsg, oh, my god!!!!!
  I am really lost by this app.
   
  thanks

  the code is like following:
   /* Command to transmit a packet */
  command result_t Send.send(TOS_MsgPtr msg) {
    if (txCount == 0)
      {
 txCount = 1;
 txLength = TOS_MsgLength(msg->type);
 sendPtr = (uint8_t *)msg;
 /* send the first byte */
 if (call ByteComm.txByte(sendPtr[0]))
   {
     post CRCCalc();
     return SUCCESS;
   }
 else
   txCount = 0;
      }
    return FAIL;
  }

    hi, ashrafalqudah
  thanks for your help:)
  I was always using MOTECOM=serial at COM9:57600, yet it doesn't work!
   
  if I upload the TOSBase into my node, the TOSBase works well, but if the SimpleCMD node can not receive message.
  I am so confuzed why I add GenericComm  into the TOSBase.nc, then the TOSBase node can't work, and the "write failed" was displayed on the SF.
   
  thanks all the same!

    hi Sam
  I faced a problem like this but I was using micaz platform not the telosb, however i solved it in very simple and unexpected solution you can try this:
  when you want to specify the baud rate when running the serialforwarder write it as number not telosb. in micaz i used  param = serial at COM1:57600  rather than param = serial at COM1:micaz
    believe me its worked.
  Thanks for all
