Hello all,
I am using lwIP/ppp in a phone for mms operations, and have some problems to
establish ppp connection.
Here is the lwip trace :
===========================
lcp_init: xmit_accm=0 0 0 0
pppMain: unit 0: Connecting
pppStartCB: unit 0

===========================
PPP logs on server side give :
===========================
Sent [LCP ConfReq id=0x22f8dc <asyncmap 0x22f8dc> <auth pap> <magic
0x22f8dc>]
Rcvd [LCP ConfReq id=0x22f9bc <asyncmap 0x22f9bc> <magic 0x22f9bc> <pcomp>
<accomp>]
Sent [LCP ConfRej id=0x22f89c <pcomp> <accomp>]
===========================
First of all, I do not understand why the request ids differ. They should be
the same, shouldn't they?
Does anybody have a clue on where to look for the problem?
The "pppInProc[0]: got 9 bytes" means data is exchanged but not recognized
by lwIP. Could this be an asyncmap problem?
We have tested our modem with small amount of data (100chars max at the same
time), so I do not think it is a problem for LCP. I will however check it
more.
Thanks and regards,
Charles-Christophe
