[EN] Help with bluetooth dongle
« on: 2018/03/02, 23:13:57 »
I just got my myself a Asus USB-BT400 bluetooth dongle.
After inserting it, the dongle is found:

Code: [Select]
root@siductionbox:/lib/firmware# lsusb  Bus 009 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 008 Device 002: ID 1b1c:1b09 Corsair 
Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 007 Device 005: ID 0b05:17cb ASUSTek Computer, Inc. Broadcom BCM20702A0 Bluetooth

dmesg tells me

Code: [Select]
bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0b05-17cb.hcd failed with error -2

I googled the chipset and it doesn't look like the firmware is included in bluez-firmware.

I found instructions (https://plugable.com/2014/06/23/plugable-usb-bluetooth-adapter-solving-hfphsp-profile-issues-on-linux) on how to load firmware, reaneme it correctly and put it in /lib/firmware/brcm

Is this the correct way of getting this device working?

Not  knowing the device I can say: Adding firmware manualy to /lib/firmware is a legit way to get devices working when firmware is not automaticaly included.

Thanks devil, after +10 years with Linux I still feel uncertain about what is legit to do and what is not.


Adding the firmware and renaming it resolved the issue. Now I can use bluetoothctl to pair and connect to a bluetooth speaker. But I can't get any sound to it. If I open up Multimedia in System Settings, the speaker is available as a playback device, but it is grayed out. What am I doing wrong?

Maybe

Code: [Select]
pulseaudio-module-bluetooth
If not installed ?, It should be by default

There are a lot of things that can be found via google, but to connect to my bluetooth earbuds I found the easiest way is to switch using Pavucontrol. My settings in multimedia were grayed out as well. When I'm finished I switch back to the speakers.

Once I realized that I haf to use profile "Off" for other devices in  pavucontrol / system settings I finally got my speaker working. Thanks for input!
