[Tinyos-help] Re: Packet format from PC to base mote through UART

[jabdo at site.uottawa.ca]

Hi Lei,

Are u trying to send the packet to Micaz using serial Forwarder and
Broadcast Inject. If not, What format are u using to send it???
Note: 10 represents the data length right?? so I think it should be 6 and
not 10. Also, since you are sending the packet to the UART so the
destination address should be the UART address.


My best regards,

Julia
