nRF9160 switch between LTE-M and Ethernet

[newUser]

Hi,

On our custom nRF9160 board we also have an ethernet interface.

We would like to be able to choose which interface should be used when a socket is created.

I am a little confused what the CONFIG_NET_SOCKETS_OFFLOAD does exactly, but I believe this disables the option to switch the interfaces at runtime, because the socket data is not going through the Zephyr stack, but instead is forwarded straight to the LTE-M modem.

Is this correct? How can we accomplish choosing which network interface (LTE-M vs. Ethernet) to use at run-time, when creating sockets?

Thank you

Hi,

Have you had any success with this? It seems like Zephyr has a socket dispatcher system that could help. I’m currently trying to achieve the same thing as you.
