Product Overview
The Lofree FLOW 2 Triple Mode Mechanical Keyboard is a compact 68-key mechanical keyboard that connects by USB-C, Bluetooth, or 2.4G wireless, so you can choose a cable or go wireless depending on the device. This Lofree FLOW 2 user guide is based strictly on the official Lofree documentation for the FLOW 2.
If you are replacing a full-size keyboard, the 68-key layout saves desk space while keeping everyday typing controls available through fn shortcuts.
Best suited for:
- Users who want a 68-key hot-swappable mechanical keyboard for work or daily typing.
- Setups that switch between wired, Bluetooth, and 2.4G without changing hardware.
Consider alternatives if:
- You need Mac or iOS multimedia shortcuts while using 2.4G or USB, because the documentation notes multimedia is not supported in those modes.
- You want VIA configuration over wireless, since VIA is documented to work only over a wired connection.
Note: The blue status indicator is your pairing confirmation: slow blinking means pairing mode, and a solid blue light for about 3 seconds confirms a successful connection.
Installation Instructions
Install the FLOW 2 by selecting a connection mode with the hardware switch, then completing the matching plug-in or pairing step. The USB-C port is used for wired data and charging, and the blue status light indicates pairing progress.
- Move the mode switch to Wired, Bluetooth, or 2.4G.
- Wired: Connect the USB-C cable between the keyboard and your device.
- Bluetooth: Long-press fn + Q, fn + W, or fn + E until the blue light blinks slowly. On your device, select Flow2-68@Lofree.
- 2.4G: Insert the 2.4G receiver into your device USB port, then press fn + R for 1 second to enter 2.4G mode.
Tip: If a wireless setup fails, re-check the mode switch first, then confirm you see the correct blue indicator pattern before retrying.
How to Use Lofree FLOW 2 Triple Mode Mechanical Keyboard
After the keyboard is connected in your chosen mode, type normally and use fn shortcuts for lighting, system layout selection, and function-key behavior. If something stops responding, the mode switch position and blue status light usually explain why.
Battery, ports, and indicators
The battery indicator shows charging and low-battery states: breathing white while charging, solid white when charged, breathing red below 20%, and rapid flashing below 5% until shutdown. The USB-C interface is the wired and charging port, and the white caps lock light reflects caps lock on or off.
Side touch switch controls
Use the side touch switch for volume and screen brightness. Slide up to increase and down to decrease, and hold fn while sliding to adjust brightness instead of volume.
Lighting, system mapping, and the top-row switch
Ambient lighting toggles between steady, breathing, and off using fn with the left or right arrow shortcut. Use the documented system switch shortcuts so Windows/Android and Mac/iOS mappings behave as intended, and press fn + Tab to switch the top row between numbers and function keys.

- Do not use the battery if you notice leakage, discoloration, deformation, or other abnormalities.
- Do not leave the battery discharged or unused for a long period of time.
- Do not short-circuit the product.
- Dispose of used batteries according to local laws or through electronics recycling.
- If liquid enters the product, disconnect power immediately and stop using it to avoid fire or electric shock. Contact customer service for inspection.
- Changes or modifications not expressly approved by the responsible party can void the user’s authority to operate the equipment under FCC rules.
Troubleshooting
Most issues come from the wrong connection mode or an incomplete pairing step. Use the symptom-based table below to restore the expected connection or key behavior.
| Problem | Cause | Solution |
|---|---|---|
| Keyboard will not show up in Bluetooth pairing | The keyboard is not in Bluetooth pairing mode. | Set the mode switch to Bluetooth. Long-press fn + Q, fn + W, or fn + E until the blue light blinks slowly, then select Flow2-68@Lofree on your device. The blue light stays solid for about 3 seconds after success. |
| 2.4G wireless will not connect | The receiver is unplugged or the keyboard is not entering 2.4G mode. | Insert the 2.4G receiver into the device USB port, set the mode switch to 2.4G, then press fn + R for 1 second. If it still fails, hold fn + R for 3 seconds until slow blue flashing, replug the receiver, and confirm the solid blue light for about 3 seconds. |
| Top row types numbers instead of function keys | The top row is set to number input. | Press fn + Tab to switch the top row to F-keys. |
Next Steps
Once your preferred mode works reliably, test lighting and function-key switching so you know the shortcuts before you need them. For key remapping, request the configuration file from customer support and use the official VIA website in wired mode only.
If you experience radio or TV interference, follow the FCC guidance to reorient antennas, increase separation, or move the device to a different circuit.
How do I switch between Bluetooth devices on the Lofree FLOW 2 Triple Mode Mechanical Keyboard?
Use the Bluetooth device shortcuts: long-press fn+Q, fn+W, or fn+E until the blue light blinks slowly, then connect on your device. A solid blue light for about 3 seconds confirms the switch.
Can I use VIA with the FLOW 2 over Bluetooth or 2.4G?
No. The documentation states that VIA supports wired connections only. Connect the keyboard by USB-C, then upload the configuration file in the VIA web app.
Why do the multimedia keys not work on Mac when I use 2.4G or USB?
The documentation notes that Mac and iOS devices do not support multimedia functions under 2.4G and USB connection. If you need media shortcuts on Mac, try Bluetooth mode instead.
