Hi all,
I am recently using Micaz platform plus Tinyos 2.0 to implement the
application BlinkToRadio. But when I used Listen tools to display
the messages sent from the mote, I didnot quite understand them.
the message header received from the mote by radio is
00 FF FF 00 05 04 00 06
Is this the default message header structure used in Tinyos 2.0,
that is
Packet type(1 byte) + Dest addr (2 bytes) + Src addr (2 bytes) +
Message length (1 byte) + Group ID (1 byte) + Handler ID (1 byte)?
Micaz platform uses CC2420 RF transceiver, but this message header
structure is quite different from the definition in Tinyos 2.0,
more specifically, in tinyos-2.x\tos\chips\cc2420\CC2420.h. How to
explain this?
If there is a default message header structure in radio
transmission in Tinyos 2.0, Where can I find it?
In addition, the first byte (00) indicates that this is an AM
packet. Where can I find the definition about this? And after the
message length byte (04), it should be the AM group id. Why I
received was 00, not the default 0x22?
I am looking forward to your reply. Thanks a lot.
Please read TEP 113. The packet sent over the serial port is not a
CC2420 packet. It is a platform independent serial packet.
