I built a handwired keyboard using nice!nano. It works fine wired, but when I set it to advertise over bluetooth it only shows up as pairable on one machine a macbook pro from early 2015.

It does not show up as a bluetooth device on:

macbook air m1
windows PC with a bluetooth dongle
ipad air (iOS17)
iphone (iOS17)
Google Pixel 7

When paired to the macbook pro everything works as expected, I can clear the profile and then reconnect. When I switch profiles no keypresses are sent and then when I switch back to the profile keypresses register again.

I have tried adding the following to the .conf file with no change to behaviour; I didn't add all these at once, one at a time while troubleshooting.

`# max bt connections
CONFIG_BT_MAX_CONN=5
CONFIG_BT_MAX_PAIRED=5

CONFIG_ZMK_BLE_EXPERIMENTAL_CONN=y
CONFIG_ZMK_BLE_EXPERIMENTAL_SEC=y
CONFIG_ZMK_BLE_EXPERIMENTAL_FEATURES=7`

I am out of ideas of what to try next. Any help is appreciated!

Solved this by clearing the flash with 'zmk_clear.uf2` from here: https://github.com/joric/nrfmicro/wiki/Bootloader#nrf52840

and then reflashed my firmware.

The only thing is that the keyboard name is SETTINGS RESET and not the keyboard I set in kconfig.defconfig

You need to remove the space after the comma in Kconfig.shield if your keyboard name is going to work
