It sounds like there's a lingering Bluetooth bond or profile issue on the Lily58 (ZMK firmware uses "profiles" for secure connections—up to 5 slots). Since you flashed new firmware and forgot the device on your Mac, the keyboard might still have an old bond preventing pairing. Here's how to troubleshoot step-by-step:
1. Clear Bonds on the Keyboard
- Power on the keyboard (switch up on both halves).
- The default keymap has
BT_CLR (clear bond) on the right thumb cluster (inner thumb key, layer 1—hold left thumb outer for layer 1).
- Press BT_CLR to clear the active profile's bond.
- Cycle profiles with BT_NXT (right thumb outer, layer 1) or BT_SEL 0–4 (if mapped). Clear bonds on all 5 profiles to be safe—old bonds can block new ones.
- Reset both halves: Press reset buttons simultaneously (or short RST to GND with tweezers).
2. On Your Friend's Mac
- Go to System Settings > Bluetooth.
- If the Lily58 appears, right-click > Remove/Forget.
- Ensure Bluetooth is on and supports BLE 4.2+ (most modern Macs do).
- Put the keyboard in pairing mode: It advertises automatically when no bond is active (LED blinks). The left half is the one that pairs—right half connects to left.
3. Test Pairing
- Try pairing to a phone first (iOS/Android has solid BLE)—if it works, the issue is Mac-specific (try updating macOS or a different USB port/adapter).
- Power cycle: Turn off (switch down), wait 10s, turn on.
- Ensure halves are connected: Left LED should be solid blue when paired; if not, see split halves troubleshooting.
If it still fails, reply here or tag me with more details (e.g., LED behavior, exact error). We can dig deeper—likely a quick bond clear! For full ZMK BLE guide: zmk.dev/docs/profiles.do we do both reset buttons at the same time with the it on or off
Power on the keyboard first (switches up on both halves). Then press (or double-tap if needed) the reset buttons on both halves simultaneously while powered on—this reboots the firmware and helps re-pair the halves to each other.
If that doesn't work, try shorting the RST and GND pins on each nice!nano with metal tweezers (powered on) for a manual reset.
After, check if the left half's LED is solid blue (indicating halves connected). Then attempt pairing to the Mac again after clearing bonds as before.
