Hi all,
I got thread cli working and now I tried to set up a thread network.
I built the sample for the nrf5340PDK with overlay-minimal-multiprotocol.conf and overlay-thread_1_2.conf

My other development kit (nrf21540dk) is running:

However they do not connect.
To figure out if the dk and pdk were actually doing something I used the "ot diag" command".
The nrf21540dk seem to receive some packets:

I'm not sure where these packets are coming from, I don't have any other thread devices running. I do have some zigbee devices here, could the nrf21540 be receiving zigbee packets?
But the nrf5340PDK does not seem to receive or send anything:

Is the nrf5340 Preview-DK not receiving or sending packets because it is no longer supported?
