I have Nexus 7 with 6.01.  Couldn't find the answer to this thru search, which is surprising because lots of links on google but nothing so far has resolved.  Essentially my tablet sees the device I am trying to pair to, but will not pair...message received says incorrect pin or passkey.  However there is no place to enter a pin, even if I had one, which I do not.  VERY FRUSTRATING.  Please help.
