Problem with 7.19.1 and 7.19.2, at least on a KNOT R: the LORA board inactivates itself and disappears randomly from the interface. The only way to bring it back is to reboot the router.
Ticket open: SUP-191492. Feel free to reference it if you open your own ticket.
I have not test KNOT with LoRa on recent beta or 7.19, I’ll try this week. Field ones run older version, since yeah there were a lot of changes in RN in 7.19/7.20.
But I think I saw more LoRa fixes in 7.20beta. So maybe 7.19.2 wasn’t a complete fix…
