Hi! I had test the same redmi airdots in more scenarios, that led me to guess that, while autoconnection is not a bug, manual connection is really an Ubuntu bug, since it worked fine in Linux Mint 19.3 in the same hardware.
These was the new tested cenarios (all these with redmi airdots phone): * Scenario 1 - Dell Inspiron 5480 with Ubuntu 20.04 in live usb mode. Exactly the same bug that in My acer from original post. I need to do annoying clicks in connection switcher until it works. * Scenario 2 - Same Dell Inspiron 5480, but with Windows 10. Manual Connection works fine. Auto connection not (maybe it's kind a airdots feature, try to connect just in more used device, instead of the last). * Scenario 3 - The acer nitro 5, same from original report, but with Linux Mint 19.3 (live usb). It works, i can manually connect with just one click (but also no auto connection). ** Attachment added: "airdots earbuds manual connecting fine in Linux Mint 19.3" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1879582/+attachment/5387955/+files/acer_mint_good.cap -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1879582 Title: [Redmi AirDots Bluetooth] I need to remove device in settings every time i want to connect again Status in alsa-driver package in Ubuntu: New Bug description: I can connect to my bluetooth phone only the first time after pair the device.
