3 years ago @CorruptMilkshake Are you managing your bluetooth profiles? Please make sure you're using an open profile when trying to connect to a new device. I believe this is failing due to a prior connection to another device. Take a look at our docs here: https://zmk.dev/docs/behaviors/bluetooth#bluetooth-pairing-and-profiles
When connecting a device, you must have a cleared profile that's ready to accept a new bond.

I'm having an issue where the board (nice!nano microcontroller with Lily58 PCB) does not connect via bluetooth. The error message on Windows is "Try connecting your device again" and error message on Android is "Couldn't pair with Lily58 Left because of an incorrect PIN or passkey." USB connection is functional, as is communication between halves.
The firmware is the default nice!nano lily58 configuration, following instructions on the ZMK website to the letter, with the only change being enabling logging. What seems to be the relevant section of the log is below.
