[Tinyos-help] CTP/TestNetworkApp sending undesirable periodic messages to serial port

[Pedro Almeida]

Hello;

I feel so bad for not thinking about the chance they were debug messages, I
assumed they were only used for TOSSIM or something like that, not for the
real implementation. Anyway, it did the trick and I got out of the messages.

What intrigues me now is the content of the messages themselves. When I read
what comes through the serial port by using the Java Listen, I get a
sequence of 27 bytes, starting with 00 FF FF, and containing the bytes
defined in the TestNetwork app. However, when I read directly the bytes,
as in Windows, I get a sequence of 8 bytes, totally different,
starting with 47 FF, and not containing the bytes manually inserted
(namely the origin mote).

How this difference and how to fix this so I can read the bytes in the tos
message:
msg->source
msg->seqno
msg->data
etc

Thank you once more!

Pedro
