> For some reason every bluetooth keyboard I have tried so far glitches every so often and sends double or triple keys or occasionally the same key a couple dozen times with no way to stop it from happening.

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?

I 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.

bluetooth is a ghetto of a protocol. sad though, as the use case is well so damn useful.

That 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.

packets 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.

Sounds 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.
