Hi @serruti,
We apologize for the confusion. The USB cable and Wi-Fi connection we were discussing are for your Spacedesk Android viewer and your Spacedesk Driver on your PC, not with your keyboard. It is expected that when you are using a non-commercial Android viewer via Wi-Fi, you won’t be able to use your keyboard. If you still want to use your keyboard without business license, you can try connecting your Mi Pad with Spacedesk using a USB cable.
