Logitech K810 Bluetooth keyboard

Fri Nov 7 11:23:02 UTC 2014

Hi. I have a problem with my Bluetooth keyboard. Is a Logitech k810. The
problem is the pairing process. Take hours to connect and lose pairing
after reboot. So I must repair and wait.
One tricky solution I found is to set no pin option and remove
/var/db/bthidd.conf and /var/db/hcsecd.keys and restart bthidd and hcsecd
service every time I reboot my computer.
Take less time (~5-15 minutes) but is more acceptable.

This is my configuration

1) cp /etc/defaults/bluetooth.device.conf /etc/bluetooth/ubt0.conf

Edit ubt0 configuration file

   authentication_enable="NO"
   connectable="YES"
   discoverable="YES"
   hci_debug_level="4"
   l2cap_debug_level="4"
   local_name="lg"
   role_switch="YES"

2) sudo service bluetooth start ubt0

3) /etc/rc.conf

   hcsecd_enable="YES"
   hcsecd_config="/etc/bluetooth/hcsecd.conf"
   sdpd_enable="YES"
   bthidd_enable="YES"
   bthidd_config="/etc/bluetooth/bthidd.conf"

4) /boot/loader.conf

   vkbd_load="YES"
   ng_ubt_load="YES"
   ng_l2cap_load="YES"

5) install hcidump from ports

6) /etc/bluetooth/bthidd.conf
