<SOLVED> bluetooth ear buds configuration (TRNDlabs)

[edcompsci]

NOt limiting this thread to just TRNDlabs, but that's the brand I have.

I have linux program blueman installed, and it recognizes my usb bluetooth adapter, but when I try to pair my earbuds to it, it asks me to enter the pin into the device I'm pairing to. Of course, ear buds don't have a keyboard in order to enter the pin to.

I tried to skip pairing and it says connected but I don't hear anything.

Anyone know how to do this? If I hold the earbuds really close to the adapter I see it tries to pair then goes to Page Timeout.

I am not familiar with how earbuds work or what bluetooth standard they follow. What desktop are you using? Cinnamon, Mate, XFCE? Then open a terminal window or konsole and provide the results from these commands

Code: Select all

lsusb; pactl list short; dmesg | grep -i firmware

With Cinnamon you should be able to remove blueman and still use bluetooth as blueman has a bug that will remove a needed part of pulse audio at every boot.

When I used Blueman I had to

Code: Select all

sudo pactl load-module module-bluetooth-discover

after a reboot, then unpair the audio device and pair with it again to be able to use it

Thanks, I will try that and post results as soon as I recharge my earbuds and try the command.

I am brand new to trying to configure any kind of bluetooth usb adapter. Does the adapter have to be the same brand as the earbuds, because they are not.

I used the command you provided but now I have no way, unless there's a terminal command maybe, to see that the buds are paired. I can turn the buds on and I get the message saying they turned on, but I'm not hearing any music. I will have to reread instructions but in case anyone knows anything to help, please share.

[JeremyB]

The adapter does not need to be the same brand as the earbuds. Your bluetooth adapter has a history of issues even in Windows and might be failing

[edcompsci]

Okay. Thanks for your help.


One last question, do you recommend any particular adapter?

[JeremyB]

For an external USB dongle, I like my IOGear GBU521 and it should work fine with A2DP audio and earbuds without any meddling. If you want to use HSP/HFP(headset/hands-free for a phone) then it needs firmware that can be found on the internet

[edcompsci]

That together with what I just found may help:

What I notice is that the instructions for the earbuds say to finish pairing I'm to enter the pairing code into the device, but the device is the earbuds, and they don't have any place to enter a code.


I'll look back at this a little later.

With the Bluetooth Manager in Linux Mint Cinnamon, when you add a new device you can choose PIN options and select automatic, 0000, 1234, and other options

Thanks for everyone's help. I'm marking this solved because the earbuds work on my new zbox nano as far as pairing, but still I am working on the audio being recognized by alsa or pulseaudio, which has been submitted using apport, since I am using them on Ubuntu Studio..
