This is not a problem. LwIP is asking for get IP addree, and DNS address. 0.0.0.0 is first negotiate addresss asked, but the server did not repsonse the request, so lwIP PPP is send again and again.

This may be. It's a TETRA network, they did some reconfigs and maybe they made a mistake. I just informed these guys to check their settings, but i have seen exactly the same behaviour on some other networks, so this is the reason why i want to know what is happening there.

I also have seen the "0.0.0.0" assignments and thought this may be the problem. But why is LWIP starting to "hammer" all these packets with upcounting ID out of the serial interface? And still the question: Is there any feedback from LWIP of the abort cause , which i can query from my application to display some troubleshooting information for the customer who configures the device for his network?

I think the problem is ACCESS Server.

PPP is failure at NCP:  network negotiate phrase.

The authorized is passed, so it is about to get IP, DNS information, but the server did not assign these.

Which platform is working as the PPP access server?
