Or any other suggestions for this problem?
Can you show output of
dmesgwhen you plug it in? Does it load any firmware file? I have a bt 5.3 dongle that by default behaves is similar way (mostly does not work) and it was old linux firmware, when I googled it I found people with same problem and solution was to copy firmware from windows driver installation to linux into /lib/firmware. After doing that it works perfectly and since then it is the best bt dongle I have.

I bought this Bluetooth dongle for a desktop computer running Ubuntu 20.04 LTS, using bluez. It works with my wireless headphones but does not get along with my Bangle.js 2. It regularly takes a dozen attempts or more to connect without giving an error, and even then it might only stay connected anywhere from a few seconds to a minute or two before erroring out and disconnecting, regardless of how close the dongle and watch are to each other. I have a laptop running the same version of Ubuntu, and its built-in Bluetooth works fine with the Bangle. Oddly, I tried this dongle on a Windows 10 system and it seemed to work fine there, too, so maybe the Linux drivers for that chipset are buggy?
To preserve my sanity, I was thinking of trying to buy a different dongle in the hope that I get one that works better. Is there anyone here who successfully works with Bangle BLE on Ubuntu or a similar distro (like Debian or Raspberry Pi OS) who could suggest a specific dongle that seems to work well with it? Or any other suggestions for this problem?
