Quick Tips

Linux Bluetooth Headset Fix. Here’s how I got my Broadcom BCM20702 chipset generic Bluetooth dongle to provide both high-fidelity and headset capability to my Bluetooth headset with mic.

Plugable USB Bluetooth Adapter: Solving HFP/HSP and A2DP Profile Issues on Linux

In a terminal:

First let’s make sure we have a compatible USB Bluetooth dongle, we’re looking for a specific/common Bluetooth Broadcom chipset.

sudo lsusb

You’re looking for Broadcom Corp. BCM20702A0 The part we care about is BCM20702. If that’s listed, keep going. If not, search the web for “Broadcom BCM20702 for sale” and invest $10 to $15 or so.

Let’s download the firmware.

wget https://s3.amazonaws.com/plugable/bin/fw-0a5c_21e8.hcd

This downloads the firmware from plugable.com’s storage at aws to your home directory. Verify the directory exists and has firmware in it. If not, you may be out of luck.

 ls /lib/firmware/brcm

Now let’s move the firmware from home to the appropriate directory.

sudo mv fw-0a5c_21e8.hcd /lib/firmware/brcm/BCM20702A0-0a5c-21e8.hcd

Now let’s make sure the naming scheme is appropriate for most kernels by giving it both a A0 and A1 naming scheme for the file.

sudo cp /lib/firmware/brcm/BCM20702A0-0a5c-21e8.hcd /lib/firmware/brcm/BCM20702A1-0a5c-21e8.hcd

Now Reboot.

Both profiles should now work without issue if you met the following requirements:

1. The right chipset in the dongle. Broadcom BCM20702-ish
2. Follow the directions exactly and rebooted.

We chill and look at some cool commands for the BASH terminal and scripts.

A fun romp through my digital music library and the tools I use to maintain it.

Get mp3gain for Ubuntu from MartIn Wimpress:

Ubuntu users should remove this package for best quality mp3 audio playback:

sudo apt purge gstreamer1.0-fluendo-mp3

Ever get confused where to find things in Linux and where programs get installed? I’ll explain what all the folders are for, and what’s in them! My Patreon : https://www.patreon.com/doriandotslash Music by MrGamer (@AndreasRohdin): https://soundcloud.com/gamermachine

Frustrated trying to get Private Internet Access (PIA) to work in elementary OS? Tried all the tricks and no dice. Then keep reading.

Also, the above link is indeed an affiliate link. Should you sign up at the affiliate link for PIA above, I get a small piece of that revenue.

Okay, disclosure done. Let’s do this. Start off by looking at this image here. Heck, open it in a new tab. you’ll likely want to make sure what you’re doing matches the contents of that image.

Note the following:

1) Use AppEditor to make sure you’re running the right file. https://github.com/donadigo/appeditor

2) The targeted run.sh in

/home/$USER/.pia_manager/pia_manager/

has

XDG_CURRENT_DESKTOP=Unity

at the VERY top of the file. Also verify your export options in the file match mine. Save and close scratch.

3) Reboot your computer.

4) From a terminal, run /home/$USER/.pia_manager/pia_manager/run.sh You’ll see

pia_nw: no process found

and then…

ERROR:browsermain_loop.cc(267)] Gtk: IA_gtk_widget_add_accelerator: assertion 'GTK_IS_ACCEL_GROUP (accel_group)' failed

And then you should see the icon appear next to the other icons in the panel.

This works on Elementary OS running the 4.13.0-31-generic #34~16.04.1-Ubuntu SMP kernel and PIA app v74.
