Nice! nanos not pairing together.

Hello. I recently had a nice nano break down so I got a replacement for the corne split keyboard. Everything seems to be fine with the new one, but I cant get it to pair with the other nice nano by turning them both on at the same time and tapping the reset button. Any ideas what might be wrong and how to fix that? Thanks

Got it! When you replace a nice!nano, the BLE bonds between the halves no longer match, so the split needs to be re-paired. Here’s the quickest path to fix it: 1) Verify firmware - Make sure each half has the correct UF2 (left vs right, and with/without nice!view). - You can grab our prebuilt files here: https://docs.typeractive.xyz/build-guides/corne-wireless/firmware 2) Clear all old bonds - On your host (PC/phone), remove/forget the keyboard. - On the left half, press the BT_CLR key on each profile (0–4). If you’re not sure where BT_CLR/BT_NXT are, see the keymap image on the firmware page above. 3) Re-pair the halves - Power both halves on. - Press the reset buttons on both halves at the same time. This helps them find each other. - Then pair only the LEFT half to your host (the right never pairs directly). 4) Still no link between halves? - Follow the steps here to fully reset split pairing: https://docs.typeractive.xyz/troubleshooting/split-halves-wont-connect - If needed, use the ZMK guide (has the exact split reset steps): https://zmk.dev/docs/troubleshooting#split-keyboard-halves-unable-to-pair Quick checks: - When you tap reset, the blue LED should blink (power is good). - Make sure the battery switch is ON. - Confirm you flashed the correct side (left/right) on the new nice!nano. If it’s still stubborn, tell me: - Which half did you replace? - Which UF2s did you flash (left/right, with/without nice!view)? - Does the blue LED blink on reset on both halves? Reply here or tag me and I’ll help you step-by-step.
