[EN] Help with bluetooth dongle
effo:
I just got my myself a Asus USB-BT400 bluetooth dongle.
After inserting it, the dongle is found:
--- Code: ---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
--- End code ---
dmesg tells me
--- Code: ---bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0b05-17cb.hcd failed with error -2
--- End code ---
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?
devil:
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.
effo:
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?
piper:
Maybe
--- Code: ---pulseaudio-module-bluetooth
--- End code ---
If not installed ?, It should be by default
ghstryder:
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.
