I have tried to pair but it only get connected. I have tested the units on other machines, so I know they work properly. I use the bluetooth applet to connect, but I don't get to the point when the units is paired properly. The keyboard is paired, but when it is used on other machines or after reboot, it has to be paired again.
The K480 have the possibility to be paired with 3 different machines, and it works with my phone and Win 10 machine. In the info tab it says ut's paired but not trusted.
Is it a way to do this right so it works? I have a Rasp Pi 4b.
