    I found that the bluetooth went to sleep way too quickly so I disabled the auto-sleep and it's been a lot better since then. I think you can toggle it by holding `fn+S+O` for a few seconds.

      It's less a kernel bug than a bad firmware decision on Keychron's part. Keychron's non-QMK keyboards all use the USB vendor/product IDs from a 2009 Apple keyboard; the "bug" was that the kernel expected them to actually behave like the device they claim to be.

      Anyway, wild seeing a Phoronix article about something I did again after all these years.

        Friendly reminder that the encryption used by bluetooth has had multiple security flaws discovered in the past, and even if it were perfect, transmitting a burst of radio energy on each keypress invites the possibility of timing attacks.

        Wireless makes sense for mice, because they have to be moved around, but the only good reasons to have bluetooth on a keyboard are Android and set top box media center PCs.
