Ok, now I understand all header, thanks. I try to send a packet (with the same header but changing Adress Bytes for Broadcast Address 0xFFFF). In byte 4 and 5 (Address byte 1 and 2) I put XOR w/ 0x20 to 0xFF but I don't receive anything.
I try to put Node Address (in this case 0) on that bytes, for byte 4-->0x20 (XOR w/ 0x20 to 0x00) and for byte 5-->0, but at this form I don't receive anything either. I'm using matlab to do everything I have explained, taking one packet first, changing the header and sending all packet across the serial port. I attached the format packet to refresh that: http://img851.imageshack.us/i/paquet.jpg/ 2011/3/7 Michael Schippling <[email protected]> > There used to be a nice description of the message format online... > which I found again through the offices of a web archive: > > http://web.archive.org/web/20060627154751/http://www.octavetech.com/pubs/TB5-01+Deciphering+TinyOS+Serial+Packets.pdf > > Looking through that and the Packetizer.java code is the best I can > do to explain what's going on. > > MS > > > Xavi Colomer wrote: > >> Oh, thanks a lot!
