I have a problem with pairing Huawei's Freebuds 3 via bluetooth on Ubuntu 18.04. I have already updated bluez til 5.50. All I got when pairing is a loading circle and then message Not set up. Does anyone got a clue?

Part of syslog looks like that during pairing:

Reset to default

Restart the bluetooth service from the console:

sudo service bluetooth restart

Open the bluetooth controller and check its working:

bluetoothctl
show

This should provide you with a name, alias and some other parameters. If not, then the following won't work and you'll need to check the bluetooth service/device.

Run the following:

agent on
default-agent
power on
pairable on

These may already be configured like this, but it doesn't hurt to run them anyway.

Check if your device is already registered:

devices

If your device is listed:

remove [MAC_ADDRESS]

***Replace [MAC_ADDRESS] with your device's MAC Address

Put your device into pairing mode and then:

pair [MAC_ADDRESS]
connect [MAC_ADDRESS]
trust [MAC_ADDRESS]

If this works, then you can exit with:

exit

    Did everything, however as always I receive that terrible: [Free1m[agent] Confirm passkey 406043 (yes/no): y Failed to pair: org.bluez.Error.AuthenticationFailed [CHG] Device FC:94:35:C1:C4:A5 Connected: no

  • After device removal it may need to obtain it again by enabling scanning with command 'scan on'

I have the same headphones, same problem and I found a way to fix that. The problem is in Bluetooth LE and using this manual I can successfully pair my FreeBuds 3 with my laptop. I hope it helps you too.

  • It may be helpful to explain the instructions contained at that link, just in case it becomes unusable at some point.

  • Thanks for the response. However it still doesn't work for me. All i get is: org.bluez.Error.AuthenticationFailed when trying to pair them manually.

  • @KrisJed It's very strange. I'm getting a message which tells me that I should verify the pin on the paired device. But because it's headphones there is nothing to check and I just click Pair. Looks like you miss that PIN verify request for some reason.

In my case on Ubuntu 20.04, I used the following commands:

bluetoothctl
devices
remove [MAC_ADDRESS]

trust [MAC_ADDRESS]
pair [MAC_ADDRESS]
connect [MAC_ADDRESS]

...and it worked!

Did you check the logs in /var/log if there is anything useful in there?

More information would be helpful, as it can be anything from "is bluetooth turned on" till "bluetooth driver broken".

  • I've added logs to the main post. What I did was turning on bluetooth, trying to pair, when I got message Not set up I turned off bluetooth. Can you recognize what can be wrong?

After a long struggle I managed to connect them. I do not know exactly what solved the problem, but my workflow was:

  1. I updated system with everything what Ubuntu told me to. There were a couple of updates during last weeks.
  2. Manually removed headphones from bluetooth devices in console.
  3. I couldn't then connect them in console so I tried in standard system's bluetooth manager and they connected, just like that.

I'm using Ubuntu 20.04 and I've uploaded blueman and etc another things in this page and the links given. However, it worked with a very simple and different way. I was connecting to the earbuds when I took them from its case, now I tried to connect it from its case (You need to open the hatch of the case and push the button behind for 2 seconds.) Once its colour turns to white and blinks try to connect from blueman through Set up a new device and after few trials and lots of patience :) finally it worked.
