I’m seeing lots of posts about being unable to update to latest firmware. I’ve had problems updating since v1.7.0. The updater shows the latest version, then as soon as I plug in the dongle the latest version switches to 1.7.0 (currently v2.1.1_rc2). I’ve tried from several different computers, all with Win 11 (Pro) 24H2.
Screen shots and log file below.
I have also had an issue with Bluetooth connectivity in Linux. I’ve tried a few different dongles, the issue has persisted since firmware version 1.6.x. I’ve updated and tried multiple playback techniques, switching from various playback codecs, drivers, systems (currently wireplumber on Fedora 42).
After anywhere from 30 minutes to a few hours, the headset just powers off. I can then power on and it reconnects.
