Re: [lwip-users] Interfacing LwIP for a radio communication

[Ivan Delamer]

No demo or sample really. Best resources are the SLIP source code and 
maybe Wiki page on the protocol. It *is* a really simple encapsulation.

As for the rest, it's going to be fully custom to your application:

- Serial port layer: implement those SIO_xxx() methods based on your 
hardware
- Address resolution: you'll have to implement some kind of table to 
match IP address to radio link

Cheers
Ivan
