Pair a Bluetooth Device using Bluez
Last Updated 3 years ago

Install bluez-hcidump

In a new terminal type:
"hcitool scan" and copy mac address XX:XX:XX:XX:XX:XX

Now in another terminal type:
"sudo hcidump -at"

You should get something like (followed by a blinking cursor):
HCI sniffer - Bluetooth packet analyzer ver 2.4
device: hci0 snap_len: 1028 filter: 0xffffffffffffffff

Switch back to your original terminal and type:
"sudo bluez-simple-agent hci0 XX:XX:XX:XX:XX:XX"

Now in the hcidump terminal you will see a few things scroll past until you get something that looks like:
2013-02-07 15:35:40.653393 > HCI Event: User Passkey Notification (0x3b) plen 10
bdaddr XX:XX:XX:XX:XX:XX passkey 66235

Type the 'passkey' in to the keyboard on the K810 and press ENTER
On success you should get "Release" and "New device (/org/bluez/..."

Now set device as trusted:
"sudo bluez-test-device trusted XX:XX:XX:XX:XX:XX yes"

You might have a connection now, but still need to:
"sudo bluez-test-input connect XX:XX:XX:XX:XX:XX"

Reboot and your device should be working.
