hi,
I try to compress IPv6 extension headers according to
"draft-ietf-6lowpan-hc". But I can not find what's wrong. I always get the
following compressed ext (part of data of serial received ):
e0(encoding) 3b(nxt_hdr) 0a(len) e0(??) 0a(Type) 08(len) 59 b7 ff 00 00
64 f0 ec
why there is one more byte e0?
So, the unpack will get wrong:
msg after unpackheaders.
nxthdr: 0x0 hlim: 0x41 plen: 11
src: 0x20 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x1
dst: 0xff 0x5 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x0 0x1
header [10]: 0x3b 0xa 0xe0 0xa 0x8 0x59 0xb7 0xff 0x0 0x0
data [1]:
0x64
I am really confused about this.
pls give me some help, if you have any idea.
thanks a lot
amy
