Instability in Multiple Bluetooth Device Usage

Hello ArchLinux, and hello everyone,

Using multiple Bluetooth devices is generally normal, but after a short period of use, some Bluetooth devices become disconnected and unusable.  Due to the unavailability of some Bluetooth devices, I have to remove the information of all Bluetooth devices, restart the Bluetooth service, and then search for and reconnect all the devices, which is quite troublesome.

First, Below is the incorrect information of the Bluetooth devices that cannot connect.

sudo systemctl status bluetooth

● bluetooth.service - Bluetooth service
     Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; preset: disabled)

Second, Some normally functioning Bluetooth devices have become undetectable due to conflicts, preventing them from being searched.

Thanks.

Re: Instability in Multiple Bluetooth Device Usage

The same Hardware, different disk and Windows10,  Multiple Bluetooth devices are very stable in use. This issue is only encountered when using Archlinux.
