I don't have any of these issues you're describing. I use a BT mouse/KB audio on Windows all the time, and use it to send files to my phone. The last time I had BT audio choppiness was in 2016 , and that was an issue with that specific phone's BT hardware. If only the file transfer speed was better (100KB/sec only good enough for transferring small files), I'd be able to leave behind proprietary file sync services forever.
