Try using btmon to get a trace of what is going on, from the error it
sounds like the remote is canceling the pairing so perhaps it times
out or something. Btw, have you checked the manual how the pairing is
suppose to be done? Did you enter the pincode in the keyboard itself?

The problem seems to be at pairing which is mandatory if the device
implements HoG profile, so I guess no command will succeed until
pairing is done properly.
