connect android phone via bluetooth

Hi,

I'm trying to connect my android phone via bluetooth. It is recognized correctly via blueman. But when I try to connect to it, it fails with the following error:

Connection Failed: br-connection-profile-unavailable

Same with bluetoothctl. I can pair with the device, but get the same error when trying to connect.

Does anyone know what this error mean, and how I could fix it?

Thanks a lot

Re: connect android phone via bluetooth

I don't know the reason for the error or what it means. However, I'm curious why you want to connect your Android phone to your computer using bluetooth. If you're wanting to just transfer files, you can do that using the USB cable supplied with your phone for charging.

Once you connect your phone to your computer using the USB cord, unlock your phone and you should receive a message with two options, one of the options being file transfer. Select file transfer and then your phone should show in a file manager. I use the Double Commander file manager and connecting my Android phone (Android 13) to my computer for file transfers works flawlessly every time under Arch and Debian.

Re: connect android phone via bluetooth

I am not the original poster, but I am having this EXACT issue. @walkingstickfan, in my case, I want to control my laptop wirelessly (phone as mouse/keyboard), I am in a hotel right now so nothing wifi-based works, so I see no option other than bluetooth.

I'd made a post for my issue before finding this one. Here is my post: https://bbs.archlinux.org/viewtopic.php … 2#p2174792
