Windows 10: Marvell Avatar Bluetooth not working

I have a Surface Pro 5 and bluetooth stopped working. It's has windows 10 and has all the updates. The driver is the latest from 5/21. I rolled it back to 1/21 and still not working.Any ideas?

Marvell AVASTAR Bluetooth broken functionality

Hello Jeffrey,

I have done what you suggested a few times. Right now the Marvell Adapter appears to be 'behaving itself'. This was after I removed all the Bluetooth devices apart from the surface cover and ran the Surface diagnostic test for surface pro's. One thing
I notice is that when the adapter is 'playing up', I go to trouble-shooter and find that is "turning on the Bluetooth radio adapter" or that it installs the Marvel Avastar Bluetooth driver again.

You haven't really answered my question. Is there a problem with the Marvell Avastar Bluetooth drivers? Is Microsoft working with Marvell to fix this problem? Is the fact that the latest surface pro's have
Intel Bluetooth adapters an indication than Microsoft no longer trusts Marvell's adapters in the surface pro?

Bluetooth is not working — troubleshoot claims I don't even have it

I have done all the following steps:

- installed bluetooth driver from manufacturer
- hit windows update
- updated / uninstalled bluetooth items listed in Device Manager and restarted the PC
- updated / uninstalled USB drivers listed in Device Manager and restarted the PC (USB drivers automatically came back but not bluetooth)
- turned on and restarted all bluetooth support in services.msc
- conducted bluetooth troubleshooting
- conducted hardware troubleshooting

 

Marvell AVASTAR Bluetooth broken functionality

Hello,

my issues started with a Logitech G603 Bluetooth mouse. On the first use it connected fine. The pairing was also flawless. However I got annoyed since every time my Surface Pro 4 went into hibernate/sleep my mouse had to be paired again. My headphones WH-1000XM2
and my Surface Pen still worked correctly.

I looked for solutions but there was no simple workaround. I'm definitely not the only one. I also saw that somebody with the original Microsoft Bluetooth mouse had this same annoying problem.

At a certain point I got to workarounds, changing something in the Bluetooth services but that did not work. Finally I wanted to update the Marvell AVASTAR Bluetooth drivers but here is where it went wrong. Some 'fixes' were to go to the Device Manager and
Show hidden devices and to uninstall the G603 driver here. I did that, but from then on I could never reconnect to the G603 ever again. After a reboot I did see the G603 come up and tried connecting to it [1], but I could never connect to it again [2] rendering
the message "Couldn't connect. Try connecting device again".

I contacted Logitech and they sent me another mouse. This did not resolve the issue, since there is something wrong in my driver folder or somewhere in my registry.

Then I got to think about if it is only the mouse or if it is the complete Bluetooth driver. In the "Bluetooth & other devices" I clicked on the option to forget the Sony WH-1000XM2. Then when I wanted to connect them again to my computer through Bluetooth
[3] and I got the same message as with the G603 Bluetooth mouse [4]. Some 'fixes' I came along again stated to uninstall the driver but now for the WH-1000XM2. However, the "Bluetooth" section in Device Manager does not seem to work the same as with the other
sections (When uninstalling COM ports in "Ports (COM & LPT)" for example, after connecting devices again they install automatically); the drivers for G603 and WH-1000XM2 never came back again.

In the device manager I went to look for other drivers for the Bluetooth Radio Adapter. However, I saw a lot of duplicate drivers. Under "Bluetooth" I see one single 'Generic Bluetooth Adapter', two 'Marvell AVASTAR Bluetooth Radio Adapter (Marvell Semiconductor,
Inc.)' and one 'Marvell AVASTAR Bluetooth Radio Adapter (Microsoft)' [5]. Under "Network adapters" I see 6 'Marvell AVASTAR Wireless-AC Network Controller (Marvell Semiconductor, Inc.)' and two 'Marvell AVASTAR Wireless-AC Network Controller (Microsoft)' [6].

Additional things I have tried are:

• Everything in the standard Microsoft fixes https://support.microsoft.com/en-us/help/14169/windows-10-fix-bluetooth-problems
• So also the Troubleshoot (which doesn't fix anything)
• I also updated the drivers to the latest release of late september (I really hoped this would fix it, but it did not).
• Show hidden devices (in Device Manager)-> uninstall hidden devices (think this doesn't work as it should under "Bluetooth")
• Uninstalling under "Bluetooth" in Device Manager the Marvell AVASTAR Radio Adapter and reboot machine. Doing this actually creates all these duplicate drivers [5,6].

Another thing I would like to ask, is it possible that disable Hardware Enumeration in the registry screws with the workings of my Bluetooth adapter? I don't think so since the Bluetooth radio adapter has its own Enumerator but I'm not completely sure.

I do not know how to proceed from this point. Could somebody help me to restore my Bluetooth functionality? I do not want to remove my Surface pen and never be able to reconnect it ever again to my Surface Pro 4.
