I just wanted to reiterate the problem in the plainest terms possible.
- Eve V with V keyboard connected by pogo pins: No missed keystrokes
- Eve V with V keyboard connected by bluetooth: Missed keystrokes
- Eve V with different bluetooth keyboard connected by bluetooth: No missed keystrokes
So, the huge copy and paste on possible bluetooth interference is not relevant here (because of 2 and 3), nor the suggestion that the bluetooth driver is faulty (because of 2 and 3) nor the suggestion that keyboard is “mechanically faulty” (because of 1 and 2). To me, the problem is that I (and some others) have a V keyboard that is faulty. I have raised the issue with Eve, and they are currently investigating.
