Re: [lwip-users] Advise on PPPoS implementation

That's a very good, point, I've been so frustrated that it didn't occur to me that I can just print the packet in my serial function.

Apologies I somehow over glanced your suggestion before.

I enabled the PPP_DEBUG and PRINTPKT_SUPPORT, and removed all filters from ppp_dump_packet() in utils.c, leaving just "pp_dbglog()" function call.

From my inexperienced point of view, the PPP side seems to work fine I guess. Is it something to do with netif?

If you could take a look, it would be greatly appreciated.

This is the output I got:

netif: IP address of interface \0x00\0x00 set to 0.0.0.0

netif: netmask of interface \0x00\0x00 set to 255.255.255.255
