Bluetooth device not connecting

GDPR-6 · June 6, 2018 at 5:37 PM

I am new to Libreelec, but the first issue I noticed when using it is the problem with connecting my bluetooth speaker. I have searched many threads, but haven't found an exact procedure how to eliminate problems during connecting. I have been figuring this for a while and I want to provide a guide for people with similar problems.

I am using Libreelec 8.2.5 on PC Intel-i5 4210 processor.

What I encountered at first was that the PC was unable to find my bluetooth speakers. I searched a few forums and they suggested using bluetoothctl for connecting the device.

Using these commands I was able to find the device, pair and mark it as trusted:

bluetoothctl

Code

power on
agent on
default-agent
scan on

Now wait for your device to show up, and continue with:

Code

pair MACAddress
trust MACAddress

I tried to use command connect MACAddress, but I always got this error:

Code

org.bluez.error.failed

Various forums suggested using pactl commands, loading modules module-bluetooth-discover or pulseaudio-bluetooth-module, but these are not available on libreelec. Other solution suggested restarting pulseaudio, and this is where i found the solution. I tried to execute pulseaudio -k, but it showed me a message saying that pulseaudio is not running.

I tried to set pulseaudio as the default audio device in the system setting. Then, I was finally able to connect my device with bluetoothctl command:

Code

connect MACAddress

In my opinion this is not how it should work and the system should be able to figure this itself. Introducing a feature where the default audio device would be automatically changed after connecting bluetooth would also be welcomed

TL;DR:

If you have trouble connecting bluetooth devices, set pulseaudio as the default audio device in the system settings BEFORE connecting device.

There's an add-on in our repo that automatically switches the audio connection to pulse when a specific BT (audio) device pairs.

Yes, I know, however the problem is that it switches the device after it pairs, which only happens once. Now I have my device paired, and it does not switch the device as I am trying to connect. Unpairing and again pairing the device every time I want to connect would be another complication of the process, as I had troubles with getting the device found by libreelec as well.

Is it some kind of branded speaker, or something cheap? .. Some cheap devices just have bad firmware.

Branded headphones, JBL 450 BT

I am trying to connect to a Logitech Bluetooth Speaker adapter that feeds to a Power Amplifier with RCA connectors (it works with everything else, except LE)

I tried two bluetooth dongles on RaspberryPI with LE 8.2.5.

Any sugestion ?

Thanks.

Some BT devices require you to "pair" them, and some require you to "trust and connect" the device.
