I'm unsure if the dongle or the keyboard is the issue but it basically stopped working.
I've tried using different computers and ports but result is the same. Is there a way to attempt to re-pair the dongle to the keyboard?
Failing that, is it possible to get hold of a dongle that will pair with the board?
Bluetooth isn't great for this and I suspect it's a Linux + Bluetooth issue (if you know you know)
