For more information on lwIP reference, there are as follows: Can you suggest me some documents? The connectivity modules provides two built-in IP stacks or an external IP stack. Below is a description of each driver API. As the diagram above shows, all stacks implement the same Socket API.

Choosing the interface also automatically pulls in the network stack as a dependency. Thank you Regards Matteo. Because the Ethernet driver requires no configuration, it does not implement any controlling interface for the application.

The interface API is the control interface for the application. Some external Wi-Fi modules and most cellular modules are in fact external IP stacks from the application point of view.

I don’t undestand which “methods” I can use. From the application point of view, there is no difference, but the network driver developer needs to be aware of that. Please note that the interface API is not the same as the network driver. In that case, the network driver implements the full Network stack API. LwIP is correctly running and I’m able to ping my board.

Results 1 to 2 of 2. Network interfaces are the application level APIs where users choose the driver, connectivity method and IP stack. It also depends on the stack used, which configurations are supported on each link layer.
