B550 Phantom Gaming-ITX/ax: Bluetooth disconnects

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   My ASRock B550 Phantom Gaming-ITX/ax seems to be incompatible to my MX Master 2S Bluetooth LE mouse. Every now and then (about twice per hour), the mouse looses connection and cannot be reconnected by switching it off and on. The bluetooth radio on the mainboard side seems to be dead for a couple of minutes, then suddenly the mouse reconnects.

My Windows 10/64 bit is freshly installed, the Intel Bluetooth driver via Windows Update is newer than the one that can be downloaded on the ASRock support page (August 2020 vs. May 2020), so I've stayed on the newer version. WLAN is unaffected.

I have tried connecting different antennas: the one that comes with the mainboard, and another one from my previous mainboard. No difference.

Is this a known problem? Is there a solution?

	I have the same issues, on my pc the bluetooth cuts out randomly. Mobo is same Asrock B550 Phantom Gaming ITX and the mouse i use is similar a Logitech MX 3. I tried multiple things: Reset/update bios Delete bluetooth drivers Install drivers from Asrock Install drivers from Intel Nothing works, i have to go to settings in windows and disable/enable bluetooth every time to get it to work Would be nice if someone of Asrock could assist with this common issue.

	For me, the issue was entirely fixed by an update to the Intel Bluetooth driver via Windows Update. Go to Windows Update, view the optional updates and pick the one that has Bluetooth in its name (or just Intel, can't remember exactly).

	Also, before the driver arrived I used a workaround: I connected my PC via Bluetooth audio to my AV receiver. That prevented any disconnects of my mouse. I guess the issue in the buggy driver was that if only a Bluetooth LE device (such as the MX Master mice) is connected but no Bluetooth classic device, something in the driver would time-out and deactivate the Bluetooth (maybe to save energy or something).

	That is indeed a possiblity, maybe it is a battery saving setting with a LE device. Will check this evening hope it can resolve, it is mainly annoying during office work. Will get back with my experience, thanks in any case!

	Same Problem here. Very Annoying. Very Bad Bluetooth Chip/Firmware/Driver Whatever.

	Edit: Same Problem on ASRock B550M-ITX/ac. Bluetooth is absolutely useless on this.
