It is just a dummy implementation, it doesn't really do anything. It is mostly used for testing, when the network stack actually runs on a different host.

Is this part for app core only ?

Typical network driver should have some IPC messages to network core and some part on netcore side.

Zephyr supports a lot of other MCUs than just the nRF5340, not all of them are multicore. Also, you don't actually have to use the network core for your network stack, if you don't use the radio.

The dummy driver shows you what you have to do to make the upper layers happy. How you talk to the lower layers is up to you to figure out.

As for how to actually communicate between the two cores, nrf/samples/nrf_rpc/entropy_nrf53 should be a good start.

Hi Didrik !

Thank you ! I wondering why I miss it.

But why it so short ? Is this part for app core only ?

Typical network driver should have some IPC messages to network core and some part on netcore side.

What simplest sample is the best for implement own serialized L2 device driver ?

Hi,

The dummy implementation can be found in zephyr/subsys/net/l2/dummy

Best regards,

Didrik
