Hi, all
I used UDPEcho and IPBaseStation in tinyos 2.x with BLIP (I guess it is
blip 1). The node and the base communicates, while a sniffer node is nearby.
There is some data sniffer catched:
7E 42 FF FF 64 00 40 03 94 3A FF 00 64 A4 01 86 00 20 09 40 00 00 00 00 00 00
00 00 00 00 00 03 04 40 C0 00 27 8D 00 00 09 3A 80 00 00 00 00 FE C0 00 00 00
00 00 00 00 00 00 00 00 00 00 64 11 01 00 00 00 00 00 00 E3 00 BE F3 7E
7E 42 09 00 64 00 12 04 D4 40 00 64 00 09 80 D0 28 00 46 5C A3 68 65 6C 70 E3
00 BF 9D 7E
7E 42 64 00 09 00 1C 04 94 3C 41 00 09 00 64 11 0A 0A 08 C0 8C 0A 08 00 64 00
46 D0 28 00 0A 2B 7B 06 02 C5 00 58 C4 7E
The above is 3 types of data catched. I tried to parse them, the result is below
7E 42 // Start flag and 42
FF FF 64 004003 94 // Tinyos header, destination addr, source addr , length,
am type and group.
3A FF 00 64 A4 01 86 00 20 09 40 00 00 00 00 00 00 00 00 00 00 00 03 04 40 C0
00 27 8D 00 00 09 3A 80 00 00 00 00
FE C0 00 00 00 00 00 00 00 00 00 00 00 00 00 64 11 01 00 00 00 00 00 00 E3 00
// the red letter are source IPv6 addr in full format.(it's wired I do not find
destin)
BE F3 7E // crc and stop flag
(I configure it as a broadcast msg)
7E 42 // Start flag and 42
09 00 64 00 12 04 D4 // tinyos header
40 00 64 00 09 80 D0 28 00 46 5C A3 68 65 6C 70 E3 00 // the red letter are 70
in decimal which I opened as a UDP port
BF 9D 7E // crc and stop flag
(It is a request)
7E 42 // Start flag and 42
64 00 09 00 1C 04 94 // tinyos header
3C 41 00 09 00 64 11 0A 0A 08 C0 8C 0A 08 00 64 00 46 D0 28 00 0A 2B 7B 06 02
C5 00 // the red letter are my payload data.
58 C4 7E // crc and stop flag
(this is a answer)
I tried my best, and the above is all I could parse. What the other part mean?
Is there any document? I had read some docs about 6lowpan which told me
dispatch, next header, but I could not see any accordance with the packets I
catched. Are they 6lowpan packets?
And another thing, when I pinged the node through base, the sniffer could catch
nothing which ping6 got responses.
Anyone who knows about it?
