Re: [Tinyos-help] How to Tunnel CTP Header Over Serial

2012-09-19 Thread kevin doran 
I solved the problem. The code should have been:

event message_t* Receive.receive(message_t* msg, void* payload, uint8_t
len) {
// ctp_data_header_t* in = (ctp_data_header_t*) payload; // Wrong:
payload is the CTP payload
ctp_data_header_t* in = (ctp_data_header_t*) msg-data; // msg is the AM
packet message, who's data begins with the CTP header.
ctp_data_header_t* out;
out = (ctp_data_header_t*) call SerialSend.getPayload(uartbuf,
sizeof(ctp_data_header_t));
memcpy(out, in, sizeof(ctp_data_header_t));
uartlen = sizeof(ctp_data_header_t);
call SerialSend.send(0x, uartbuf, uartlen);
return msg;
 }

This may help someone else who has this issue.

Regards,

Kevin

 Can you check if you are receiving the proper bytes corresponding to
 the message on the PC side using seriallisten or serialforwarder and
 sflisten? If you are receiving proper bytes, the problem is in your Java
 code. Otherwise, the problem might be on the mote side.

  }
 
  synchronized public void messageReceived(int dest_addr, Message msg) {
  //never called.
  }
  }
 
  The CtpDataHeader class was created with MIG.
 
  Any thoughts on what I am doing wrong?

[Tinyos-help] How to Tunnel CTP Header Over Serial

2012-09-10 Thread kevin doran 
Hi,

I have been struggling for days trying to tunnel a CTP header over serial
and receive the header in Java. I have just modified the
MultihopOscilloscope program. Here is my code:

as follows:

event message_t* Receive.receive(message_t* msg, void* payload, uint8_t

ctp_data_header_t* in = (ctp_data_header_t*) payload;
ctp_data_header_t* out;

sizeof(ctp_data_header_t));
memcpy(out, in, sizeof(ctp_data_header_t));
uartlen = sizeof(ctp_data_header_t);
call SerialSend.send(0x, uartbuf, uartlen);
return msg;
}

public class HeaderReceiver implements MessageListener {

void run() {
mote = new MoteIF(PrintStreamMessenger.err);
mote.registerListener(new CtpDataHeader(), this);

synchronized public void messageReceived(int dest_addr, Message msg) {
//never called.
}
}

The *CtpDataHeader* class was created with MIG.
