Bluetooth dongle issues in Xubuntu 16.04

russptater · 09-17-2020, 08:14 PM

What's up, guys. I've recently purchased a USB bluetooth adapter and some peripherals. Under Windows 10, I am able to easily pair and connect these devices. Under Xubuntu, though, that's a different story. I can see the devices, pair them with the computer, and even connect them. However, within a few seconds, the status bars in the bluetooth manager fade away and the connection is lost.

Here's what Bluetooth related logs I get from dmesg.

Code:
