Using secondary bluetooth adapter

[Meokran]

I have a wifi card with a combined wifi/bluetooth chip mt7921e. It doesn't work good with both bluetooth and wifi on. So i had to switch off bluetooth and add a usb adapter. I did it by adding udev rule. After the reboot "rfkill list" shows primary adapter on mt7921e as "soft blocked: yes " and I can use my wifi card normally. But blueman icon is gray like bluetooth is disabled although "rfkill list " shows that secondary usb adapter isn't blocked. When I push blueman icon it enables primary adapter, rfkill shows it status as "soft blocked : no" and issues with wifi reappears. But only after this i can connect my headphones to usb adapter and then run rfkill block to disable primary one again. "hciconfig -a" shows only secondary usb bluetooth adapter. Is there a way to force blueman recognize only secondary usb adapter and ignore primary one?

While we store the latest selected adapter for blueman-manager we don't make use of that in the applet/tray. It shouldn't be too difficult but it will require some time and effort hunting down all the places blueman now makes assumptions.
