Hi !!
I have some problems with the message transmited from the radio CC2420 of the micaz in tinyOs 1.15. I receive the whole messege via RS232 with the TOS_BASE,and I'm trying to identify all the fields. This is the messege I receive and the fields I know:
byte 0: 126 -> sync byte
byte 1: 66 -> I don't know what means this byte????
byte 2 and 3: 255 and 255 -> adress
byte 4: 0 -> type
byte 5: 170 -> group id
byte 6: 29 ->lenght
byte 7 to 36: -> payload
byte 37 and 38:14 and 18 ->CRC
byte 39:126 -> sync byte
From byte 2 to byte 38 are defined in the TOS_Msg
The first byte and the last one, I supose that are syncronism bytes and in all the messeges I ' ve received is always 126, is this true?,is this always constant?
The second byte, could anybody tell me what means?
And how can I check the CRC bytes?
Thank you in advance
