Hello,
I'm using latest master branch lwip from 28 Feb 2016 in FreeRTOS environment.
I have a problem with PPPoS when interfacing with 3G modem.
Sometimes ppp netif cannot authenticate/obtain IP address.
What makes it even more difficult to solve is that it only happen in about 30-40% cases.
Attached logs for both cases:
ppp_dbg_err.txt - connections attempts with this problem.
ppp_dbg_ok.txt - when everything connects just fine.
Could someone give me a hint if this issues can be due to PPP misconfiguration in lwipopts.h (I didnt change anything in PPP configuration, all settings are default).
