No have keyboard USB

Hello, today I received my rock4 SE card but I don’t have a USB keyboard and mouse but only bluetooth. I installed the ubuntu server os is it possible to connect a bluetooth keyboard at startup? Also I would like to install the “xubuntu-desktop” package later, is it compatible with the card?

Thanks in advance.

I found the solution if it helps anyone: I plugged the card into an ethernet port on my router. Then I went to my router setting to find the IP address of my rock4 board. Finally I connected to the card by the SSH protocol (with putty for windows) then I activated the bluetooth and connected my keyboard according to the documentation.

Xubuntu desktop is compatible after updating the sudo apt-get packages.
