808 / Logitech K810 bluetooth keyboard

My 808 recognizes the Logitech K810 as a bluetooth keyboard, I can pair using the 808 generated passcode, but then I get "Unable to create Bluetooth connection". The K810 remains listed as a keyboard paired device. Same results with a FP1 701.



Suggestions? Has anyone successfully used the K810 with a Belle device?



I've paired and used the same keyboard with my PC and a Moto G.
