[lwip-users] lwip PPPoS + ESP8266 wifi module

[Andrea Marangon]

Hi everyone,

I'm using lwip on the ESP8266 wifi module.
This module is connected to my card and communicates via PPPos (the PPP client is the Wifi module).

Now I need to receive and transmit TCP and UDP packets via Wifi.

 

Initially I created two TCP sockets (netconn), one client and the other server forwarding the data via buffers, but it is very expensive in time and memory.
I have doubts about this implementation considering that I will have to do the same with the UDP transmission.

 

 

Board(10.11.12.13) --> PPPoS --> netconn TCP client(10.11.12.13) --> netconn TCP server(172.16.0.1) --> mobile system (172.16.0.2)

 

 

I thought of using the network interfaces (netif, one the PPPoS and the other the WiFi) to do a kind of forwarding...

could this be the right way? Can the UDP part coexist?
Do you have any suggestions?

 

Thanks in advance

 

Andrea
