Permission denied when I try to pair to a Bluetooth speaker on Ubuntu 14.04

Question

I get the following error inside /var/log/syslog on Ubuntu 14.04 when I try to pair with my Bluetooth speakers (although it used to work well few days ago:

Mar 15 19:58:39 hakim bluetoothd[1395]: Permission denied (13)

Do you know what's causing this error? and whether I should change my Bluetooth manager (note that my system is up-to-date)?

Answer 1

I solved this issue, simply by removing the bluetooth device from the bluetooth icon on the menu bar, re-scanning, and adding it.

Answer 3

This Wiki helped me out a lot.

Os = Ubuntu Mate (Release 20.04 LTS (Focal Fossa) 64-bit)

 Release 20.04 LTS (Focal Fossa) 64-bit

 MATE 1.24.0

 bluetoothctl version = 5.53

Procedures I followed on the Terminal:

$ bluetoothctl agent on

$ sudo bluetoothctl --monitor

# scan on

# pair xx:xx:xx:xx:xx:xx ...(Here input your device's address from the scan results) - You will be presented with a pin request ... usually 1234 or 0000(For speakers and/or headsets) should work. If you are pairing with a phone you can use any four digit pin since you are gonna input the same on your device...

`[agent] Enter PIN code:` 0000

# connect xx:xx:xx:xx:xx:xx (again your device's address)

# trust xx:xx:xx:xx:xx:xx ... (for future auto-reconnects)

Answer 4

In my case, the cause of the error was that the audio device I wanted to connect to was already paired to another device. Disconnecting it and rebooting the device solved the issue.

Answer 5

It could be that your user doesn't belongs to bluetooth group, you can review your grous typing id command in a terminal or add your user with:

sudo usermod -a -G bluetooth $USER
