Hi Om_p:

Thanks for the pointer. I turned on the serial listener on mote #0 and was
able to see the receive raw output.  I set it up like:

PC ----- #0 -------------#1--------------------#2.

I have some further question regarding the output:

00 FF FF 00 01 17 3F EE 00 01 00 0A 00 01 14 EE 00 01 00 14 00 00 00 0A CA
FE 00 00 00 00 00
00 FF FF 00 00 09 00 16 21 00 27 00 02 00 02 34 6A
00 FF FF 00 01 17 3F EE 00 02 00 0A 00 02 27 EE 00 02 00 27 00 01 00 98 CA
FE 00 00 00 00 00
00 FF FF 00 00 17 00 EE 00 00 00 00 00 00 77 EE 00 00 19 77 00 00 00 00 CA
FE 00 00 00 00 00
00 FF FF 00 00 09 00 16 20 00 77 00 00 00 00 34 6B
00 FF FF 00 00 09 00 16 50 00 00 00 00 00 00 34 6C
00 FF FF 00 00 09 00 16 21 00 15 00 01 00 01 34 6D
00 FF FF 00 01 17 3F EE 00 01 00 0A 00 01 15 EE 00 01 00 15 00 00 00 0A CA
FE 00 00 00 00 00
00 FF FF 00 00 09 00 16 21 00 28 00 02 00 02 34 6E
00 FF FF 00 01 17 3F EE 00 02 00 0A 00 02 28 EE 00 02 00 28 00 01 00 98 CA
FE 00 00 00 00 00

According to the message type definition in TestNetwork.h using the
following example I can see:

00 02 00 28 00 01 00 98 CA FE 00 00 00 00 00

that 00 02 is the 2 byte node ID, 00 28 is the seq no., 00 01 is the parent
ID, 00 98 seems to be the metric, CA EF is the data. but the hop count is
always 0 for node #2. I can see it always set to 0 in the TestNetworkC.nc.
Isn't it supposed to be 1 or 2 in this topology? What about send count and
send success count?

Thanks.

-David
