I am trying to connect to a Bluetooth audio device on fully updated Raspberry Pi 3 running Jessie using the following:

pi@raspberrypi:~ $ bluetoothctl [bluetooth]# power on Changing power on succeeded [bluetooth]# discoverable on Changing discoverable on succeeded [CHG] Controller YY:YY:YY:YY:YY:YY Discoverable: yes [bluetooth]# pairable on Changing pairable on succeeded [bluetooth]# agent on Agent registered [bluetooth]# default-agent Default agent request successful [bluetooth]# scan on Discovery started ... [NEW] Device XX:XX:XX:XX:XX:XX Device Name ... [bluetooth]# pair XX:XX:XX:XX:XX:XX Attempting to pair with XX:XX:XX:XX:XX:XX [CHG] Device XX:XX:XX:XX:XX:XX Connected: yes [CHG] Device XX:XX:XX:XX:XX:XX UUIDs: ########-####-####-####-############ ########-####-####-####-############ ########-####-####-####-############ [CHG] Device XX:XX:XX:XX:XX:XX Paired: yes Pairing successful [bluetooth]# trust XX:XX:XX:XX:XX:XX [CHG] Device XX:XX:XX:XX:XX:XX Trusted: yes Changing XX:XX:XX:XX:XX:XX trust succeeded [bluetooth]# connect XX:XX:XX:XX:XX:XX Attempting to connect to XX:XX:XX:XX:XX:XX Failed to connect: org.bluez.Error.Failed

One the GUI Desktop a popup appears:

Connection failed - GDBus.Error:org.bluez.Error.Failed: No such file or directory. Try to connect manually.

Both Bluetooth devices I've tried work with other devices

I've run both

sudo hciconfig hci0 up hcitool scan

and was able to see the device under scan

Any ideas?

    What kind of audio device are you trying to connect to? Is it a set of Bluetooth speakers for playing Pi audio? Perhaps Bluetooth headphones, again for playing audio? Is it a Bluetooth audio source such as a cell phone or car and you want to play audio from speakers attached to your Pi? Commented May 31, 2016 at 5:06
  • Maybe updating rpi firmware might solve it and then sudo service bluetooth restart && sudo service bluez restart Commented May 31, 2016 at 5:30
  • @Kolban I've tried both Bose SoundLink and Bluetooth to 30 pin adapter (my ultimate goal) Commented May 31, 2016 at 22:32

Try to do:

pulseaudio --start

And after:

[bluetooth]# connect XX:XX:XX:XX:XX:XX

This question is pretty old, But even now I had come across similar issue: I will detail you how I was able to fix this for current version of raspbian 10.

(i) Install Pulse audio tool

sudo apt-get install pulseaudio pulseaudio-module-bluetooth

(ii) Start Pulse audio

pulseaudio --start

(iii) Now turn on your bluetooth speaker , and make it discoverable, then type this in rpi terminal

bluetoothctl

(iv) Power On the bluetooth

power on

(v) Set bluetooth to default agent

agent on default-agent

(vi) start the scan

scan on

Now you will see the list of devices copy the mac address of your speaker

pair xx:xx:xx:xx:xx:xx

trust the device so that next time speaker turns off and on it automatically connects trust xx:xx:xx:xx:xx:xx and finally connect

connect xx:xx:xx:xx:xx:xx sudo reboot now

After reboot your device should automatically connect, and any audio should be transmitted,

If not you may have to externally try making bluetooth speaker your default speaker Try this: Go to config.txt and disable snd_bcm2835 default output, type in following command

sudo nano /boot/config.txt

scroll-down till you find dtparam=audio=on and replace it with #dtparam=audio=on save the file using ctrl+O and enter, then ctrl+X. Reboot your pi, sound should be coming out to speaker.

Hope this helps! source: https://rpios.blogspot.com/2020/09/connect-bluetooth-speaker-to-raspberry.html

I had this exact problem .I find that it works if you install blueman and run that. Then run pulseaudio --start. Open up blueman on the devices tab and search for devices. It should then find your device. Click pair and make sure it is set as a trusted device. Then go onto pavucontrol and set the output device to high fidelity A2DP or something similar.

    Could you please give some kind of explanation as to what this code does. This does not answer the question. Commented Dec 11, 2017 at 7:38
