Error Bluetooth version 43 encountered.
Error Bluetooth version 43 encountered.
I don’t have Bluetooth right now. It was missing before and I tried fixing it. Steps I did: reinstalled drivers, updated Windows (version 11 25H2), fixed BIOS (motherboard 650B with Wi-Fi, BIOS 3287), watched many YouTube videos. All tried the same and nothing worked. In Device Manager I saw an error with the Bluetooth driver (see picture 1). I used the Windows troubleshooter, but it kept saying no signal and then suggested it could. Then I checked the Services app and set Bluetooth to automatic and running (see picture 2). Honestly, I’m stuck trying everything. If anyone knows how to fix this, please help! Update: It seems I found a solution—it’s really confusing. I decided to turn off the PC and left it on for an hour. After reconnecting everything, Bluetooth worked again. Probably fixing the capacitors in the power supply helped. This was the last thing I thought about for such a problem—it’s really frustrating!
If possible, request a replacement. Otherwise, turn off the device and invest in an aptX HD compatible dongle such as Ugreen's BT5.3. Alternatively, opt for a few BT6.0 dongles (needs Barrot drivers). You'll maintain consistent and reliable Bluetooth performance either way. If that fails, check the motherboard for shorts and gently tap it with a screwdriver. If still no improvement, disable the device and switch to a dongle.
Updated: (Fixed) The solution surprised me a lot. I decided to shut down my PC using the power supply and left it off for a while. When I came back, everything seemed normal again—Bluetooth worked instantly. I guess discharging the capacitors in the power supply resolved the problem. That wasn’t something I’d have considered before... total chaos!
