Flashing uf2 to split

You may refer to the demo for flashing procedure. Details as follow:

1. Connect left and right splits to your pc (both connect together using type c cable). You also can flash one side each time without using two cables.
2. Put right into bootloader mode (press the reset button), one window is popped out showing "nicenano" folder. Dont do anything yet, remember this folder as right split.
3. Now press reset button on your left split, one window will be popped out as previous step.
4. Drag left and right uf2 to respective folders.
5. Do not disconnect right split yet.
6. Remove left split from type c cable. Proceed to First time bluetooth connection to connect your board to pc. If successfully connected, you shall able to type without cable now.
7. If so, remove the right split from type c cable. Both should be working good now!
8. If you dont have extra usb c cable...You can do left first, then quickly move to right so the right can sync with left.

How to charge?

1. Flip your power button on while charging. If you turn it off means nothing is charged.
2. You can charge both sides together with usb c cable, not a problem.
3. You can charge while using it, but we dont encourage to continuously plugging in because battery may degrades.
4. If you would like to do it in wired mode, you can plug in but flip the power button off. So charging doesnt occur and battery doesnt degrade.

Common Issues and Troubleshooting

1. Mac or Window OS connected but not responding, this is working for Bluetooth 5.2 Windows.
2. Master connected and can type, but not slave refer to Split Keyboard Halves Unable to Pair.
3. You may compile the reset.uf2 yourself or get it from setting reset.uf2.
4. The board is pre-flashed with the mouse-native.uf2. You may always use these to test the board.
5. No key is registering: have you toggled the power button? (if you have one)

Further Troubleshooting Trial and Error

1. For supermini: when i connect cable to pc, double press it, call out a nicenano explorer to lemme drop the new uf2. If i dont drop new firmware and un-plug it, then re-plug back, the nicenano folder will still pop out. I cant type anything. << this is normal.
2. For supermini: by referring to above, if i unplug the cable. Flip power button off and on again. My firmware remains. I can type again, but i did not drop in new firmware. When i plug in the usb, no nicenano folder pop out. << this is normal.
