This would make the device unusable to me. I wonder if others have had the same issue? Fundamentally, I need typing to be reliable. I guess this probably doesn’t happen via USB keyboards?
- t-3 2y agoThat sounds to me like some kind of retransmission error - a packet with a keystroke is being sent but the ack is not received so another packet is sent? I know nothing at all about if/how bluetooth actually manages reliability though, so could be unlikely or totally impossible.
- TickleSteve 2y agopackets are sequenced, integrity checked and encrypted to prevent replay attacks so unlikely to be a simple "send packet again" issue. More likely a key debounce issue or driver issue.
- konradb 2y agoI get this when using my Bose QC bluetooth headphones near my keyboard. Sometimes it doesn't happen much, sometimes it happens every half hour. It doesn't happen when I don't use the BT headphones. I wonder if this issue is something to do with interference or radio power or faulty bluetooth stacks.

- hedora 2y agoSounds like rf interference from your computer or something. Try getting a 3-6’ USB extension cable, and plug a Bluetooth dongle into it, then route it away from your machine.
