Bluetooth periodically cutting out and spamming last pressed key
Hi,
i’ve had my corne for a bit now, but periodically the bluetooth connection will cut out and the last pressed key will be spammed. After a bit the keyboard will seem to reconnect and work normally again (until the problem occurs again). I am currently only using linux, but the problem also has occurred on windows. When this happens, the icon in the top right of the nice!view will turn into an X

Thanks for the detailed description. The X on the nice!view means the BLE link to your host dropped; when that happens the host keeps repeating the last key until it gets the key-up after reconnect.
Try these steps:
Quick checks
- Charge both halves fully. Important: the power switch must be ON to charge. See Batteries: https://docs.typeractive.xyz/build-guides/corne-wireless/batteries
- Test over USB: plug the left half in and type. If it never happens over USB, it’s a BLE-only issue.
- Reduce interference: keep the left half close to the receiver, avoid metal between, try a USB BT dongle on an extension near the board.
Improve BLE stability (firmware)
- In your ZMK .conf, add:
CONFIG_BT_CTLR_TX_PWR_PLUS_8=y
CONFIG_BT_CTLR_PHY_2M=n
These improve range and stability. Details: https://docs.typeractive.xyz/troubleshooting/poor-range
- Rebuild/flash both halves. If you want a quick test, flash our default Corne firmware: https://docs.typeractive.xyz/build-guides/corne-wireless/firmware
Clean pairing
- Clear the bond on the active profile from the keyboard (&bt BT_CLR), remove the keyboard from your OS Bluetooth list, then re-pair. Profiles/bonds explained here: https://docs.typeractive.xyz/troubleshooting/keyboard-wont-pair
Split link note
- If you notice it only when pressing keys on the right half, also reset both halves together and follow: https://docs.typeractive.xyz/troubleshooting/split-halves-wont-connect
If it still happens, please reply/tag me with:
- Does it happen on battery, USB, or both?
- Approx distance to the receiver and any dongle used
- Whether both halves are charged and firmware you’re on
Happy to dig deeper!

both halves will be charged and on the default typereactive corne with nice view firmware. they will be directly in front of my laptop
@TyperAI both halves will be charged and on the default typereactive corne with nice view firmware. they will be directly in front of my laptop
Thanks for the details. The X on nice!view indicates the BLE link to the host dropped, so the host “holds” the last key until it sees key-up after reconnect.
Since both OSes show it and you’re on our default firmware, try these in order:
1) Reflash with stronger/more robust BLE settings
- Add these to your ZMK .conf, rebuild, and flash both halves:
CONFIG_BT_CTLR_TX_PWR_PLUS_8=y
CONFIG_BT_CTLR_PHY_2M=n
- These improve range/stability in noisy environments. Docs: https://docs.typeractive.xyz/troubleshooting/poor-range
- If you need a quick baseline first, reflash the latest default from our firmware page: https://docs.typeractive.xyz/build-guides/corne-wireless/firmware
2) Clean bonds and re-pair
- On the active profile, press &bt BT_CLR on the keyboard.
- Remove the keyboard from your OS’s Bluetooth list.
- Re-pair on that same profile. If you’ve used multiple profiles, cycle through and clear each one. Docs: https://docs.typeractive.xyz/troubleshooting/keyboard-wont-pair
3) Refresh the split link
- Press reset on both halves at the same time, then let them reconnect. If needed, follow: https://docs.typeractive.xyz/troubleshooting/split-halves-wont-connect
Notes
- Charge with the power switches ON (just to be sure). Battery guide: https://docs.typeractive.xyz/build-guides/corne-wireless/batteries
If the issue persists after steps 1–3, please reply/tag me with:
- Rough frequency (e.g., every X minutes)
- Whether it happens when typing on left, right, or both
- Whether it ever happens while connected over USB
Happy to help you dial this in.
