Logitech K810

Hey guys,

has somebody managed to pair the keyboard?

I tried it using blueman and bluez, the blueman manager detects the keyboard but fails to set it up (auth failed after entering the key). I can pair it once without a key, but in order to connect it on the next boot I have to reset the keyboards bluetooth connections.

I've also tried this: http://devasive.blogspot.de/2012/11/ubu … iring.html

"sudo bluez-simple-agent hci0 XX:XX:XX:XX:XX:XX" returns either a timeout or auth failed. Other bluetooth devices work well.

Re: Logitech K810

Hi there..
I had the same issue as you but I solved it while playing around on LinuxMint. The issue is that once you type in "sudo bluez-simple-agent hci0 XX:XX:XX:XX:XX:XX" the computer waits for a passkey, which never arrives, because you don't know what it is. Using the "bluez hcidump" tool (install if required), you can see what the passkey is and type it into the K810 before the connection times out.
Below is copied & pasted from the link you mentioned, plus what I did to get my K810 to work:


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"

Now reboot and hope for the best!


I have no idea why this doesn't work in the GUI as I would assume it does the same as what happens in the terminal. Only thing I can think of is the su rights.

Re: Logitech K810

Sorry to re-awaken this topic, but I have just purchased one of these keyboards in the hope this would work within Arch.  However I am having issues with pairing the device.  I have followed the advice as mentioned in this post but my hcidump -at output does not provide a passkey.
Instead of the passkey output I recieve

    status 0x00 bdaddr 00:1F:20:92:41:04

I have tried two different bluetooth devices both give the same response.

I have searched google for the error and most are dated over a year ago.  Once points to a BlueZ kernel issue, which after a year I would hope to have been resolved.
http://www.spinics.net/lists/linux-blue … 27600.html

Another points to blueman causing the problem and suggests removing the package.  I'm not using blueman.
https://bbs.archlinux.org/viewtopic.php?id=146617

Am I missing something obvious?

I'm fully aware that once I enter the passkey it will work, but without the visibility of the key I'm a bit stuck.  The key also changes every time.  It works quite happily on android devices.

I did manage to get it briefly working using the hidd command, however as soon as the keyboard sleeps it stops working until I reissue the command, not very useful.

I appreciate any help.

Thanks.

command used to start pairing is : -

bluez-simple-agent hci0 00:1F:20:92:41:04


Please not full text of dump in case it is needed is: -

Re: Logitech K810

Just in case anyone is interested.  Changing the bluetooth adaptor solved this particular problem.  I'm now using an oldish Belkin Bluetooth adaptor.

Bus 003 Device 004: ID 050d:0131 Belkin Components Bluetooth Device with trace filter

The above device resolved the problem with the K810.

Thanks.

Re: Logitech K810

Under gnome 3.10, the following worked for me (based on the post by @panitoni above):

Turn on bluetooth via gnome settings. In a terminal run:

$ sudo hcidump -at

Monitor this terminal and initiate adding a new device via gnome bluetooth settings. You'll see the passkey required in the terminal during this process, which you can enter and after which gnome bluetooth settings successfully completes the pairing.

Re: Logitech K810

Whether this is new post gnome 3.12 update, I had problems with the k810 not reconnecting automatically. This is solved by running bluetoothctl as root and trusting the device. Example:

# bluetoothctl
[bluetooth]# devices
Device 00:1F:A2:1E:C7:CB Logitech K810
[bluetooth]# trust 00:1F:A2:1E:C7:CB

This must of course be done after successful pairing.
