Re: Activating Bluetooth on intel AX200,AX201,AX210 modules

HI

      it is   the  hccontrol  'reset'   command   on line 130  of the  
/etc/rc.d/bluetooth  start script that  times  out.

   Bjoern  has  a  fix  for  it  that  loops  the  reset  untill it  
succeeds.   but  it  does not  seem  to have  been  added  to the  
source  tree  yet ,

https://reviews.freebsd.org/differential/changeset/?ref=1332283

  ( at  least  i cant  find a commit  message  with  that comment  )

   then  there  is  some  additional  issues  that  I  have  not 
investigated  yet.
