How to fix delayed/stuttering issues with MX Keys Keyboard with Bolt receiver
Not sure if anyone will see this since this community isn't active, but I refuse to post on reddit.
It's an ugly solution, yet so far the only one I've found that consistently works: Get a USB extension cord and plug the bolt receiver into that. Then place the receiver close to your keyboard.
I've tried all the USB ports. The USB extension cable is currently plugged into the last port that was causing stuttering. Sometimes it would be stutter free for a while, then come back again. Ever since I tried this method, I haven't had a single issue, so it makes sense that it's an interference issue.
Anecdotally I've heard of interference issues with Logi Bolt. Sounds like it's based on Bluetooth LE 5. Have you tried to bluetooth connect without the receiver?
I have noticed that both the Bolt Receiver and the older one seem to give issues when connected directly to rear/internal usb ports, it does make me feel like its some interference issue. I also recall the receivers used to come with extension cables but havent seen one in a while.
