Re: [web-bluetooth] NotSupportedError: GATT Error unknown when writing to device using web bluetooth API (#532)

I ran into something like this around the Windows 10 2004 update. It turned out that Windows changed how devices were queried and started using "find by type value request" instead of "read by type request" (or something like that). The BLE device didn't handle this new request properly which "Unknown" errors after a timeout.
