[Tinyos-help] Help in reading Data of Listen and ListenRaw

[Pablo Gil Montaño]

I know the format received with Listen, just in case it can help you, I describe the fields in order, and beteween parantheses the number of bytes.

Length (1)
Frame Control Field (2)
Dat sequence number (1)
Dest PAN address (2)
Dest address (2)
Active Message ID (1)
Group ID (1)
The rest dispayed bu Listen is the payload (it will depend on the data structure you are sending).

You must take into account the fact that when you have two bytes, the first one displayed on screen is the lower byte, so if you have 01 00 in the address field it corresponds with address 0x0001.
