I'd suggest googling this particular phrase: octave deciphering tinyos
packets
The PDF file can be found here:

Hope it helps.

Hi, I have a question about writing packets from the PC to the BASE
STATION
which will send out packets to the entire mote network.
Basically I'm using the file xerial.c from the xlisten application
(contrib\xbow\tools\src\xlisten) as a template, (note xbow directory is
something I got off www.crossbow.com using mica2 motes).
My question is is that I want to send out my own message that has a
specific
type of protocol in the payload of the TOS_MSG.....
I'm guessing I need to send this out to the serial port:::
7e 42 FF FF 00 7d 0A 1 2 3 4 5 6 7 8 9 A AA BB 7E
where AA BB is some random CRC #, FF FF is I want to broadcast this
message to
the entire network, 7D is the group number, and 0A is the length....
Is this correct? Its funny because I'm not sure where that 00 7d comes
from,
I thought the group ID was only 8 bits long, or is it 16 bits long? And
a
final question is, I know how to calculate the CRC, but is the CRC
calculated
starting from the message address values to n - 1 bytes or the message
type to
n - 1 bytes??
I'm also assuming the program TOS_BASE will receive this data and
automatically create a packet and foward it to the network based off
what I
sent it right?
