Redragon K688SP-RGB-PRO BRAGI PRO: driver, software, Bluetooth, and 2.4 GHz in Windows 11/10

Last Updated on 18.09.2026 by DriverNew

Redragon K688SP-RGB-PRO BRAGI PRO is a mechanical gaming keyboard with three connection methods: via USB-C cable, through a 2.4 GHz wireless receiver, and via Bluetooth. A separate Redragon system driver is not required for normal operation: Windows automatically uses standard HID drivers.

The proprietary Redragon program is required for additional settings, including supported key assignments, macros, and RGB lighting options.

Does Redragon K688SP-RGB-PRO need a driver?

A separate Redragon driver is not required for normal text input.

1. Connect the keyboard to the computer using one of the supported methods.
2. Wait a few seconds while Windows detects the device.
3. Open any text editor.
4. Test text input and the main keys.

If the keyboard works, the standard HID driver has already been installed automatically by Windows.

There is no need to look for a universal K688SP driver or use third-party automatic driver update programs.

The Windows driver and the Redragon program are different components

The standard Windows HID driver provides basic keyboard operation.

Redragon Software is an additional configuration program. It is used for supported programmable functions, macros, and advanced RGB settings.

If you are satisfied with the keyboard’s factory settings, you do not need to install the proprietary software.

K688SP-RGB-PRO connection methods

How to connect the keyboard via USB-C

1. Connect the USB-C cable to the keyboard.
2. Connect the other end of the cable directly to a USB port on the computer.
3. Select wired mode according to the switch on the keyboard case.
4. Wait for Windows to detect the device.
5. Test text input.

A wired connection is recommended for initial troubleshooting. If the keyboard does not work wirelessly, first test it specifically via USB.

How to connect K688SP-RGB-PRO via 2.4 GHz

1. Switch the keyboard to 2.4 GHz mode.
2. Connect the included USB receiver directly to the computer.
3. Wait a few seconds.
4. Test text input.

If the keyboard and receiver are already paired, the connection should be established automatically.

If 2.4 GHz mode does not work

Owners of wireless keyboards sometimes encounter a situation where Windows detects the USB receiver but the keyboard does not respond.

Check the problem step by step:

1. Make sure 2.4 GHz mode is selected.
2. Fully charge the keyboard.
3. Connect the USB receiver directly to the computer without using a USB hub or docking station.
4. Try another USB port.
5. Turn the keyboard off and then back on.
6. Test operation via USB-C.
7. Test Bluetooth.

If USB-C and Bluetooth work but 2.4 GHz does not, the problem no longer appears to be caused by a missing standard Windows HID driver.

Connecting via Bluetooth

K688SP-RGB-PRO supports Bluetooth connectivity. For initial pairing:

1. Switch the keyboard to Bluetooth mode.
2. Enable pairing mode using the key combination intended for your revision.
3. Open Bluetooth settings in Windows.
4. Add a new device.
5. Select the keyboard from the list of detected devices.
6. Complete pairing and test text input.

If the keyboard was previously connected to another device, disconnect the old connection if necessary or select another saved Bluetooth profile if your revision supports one.

Bluetooth works, but the Redragon program does not detect the keyboard

This is not necessarily a malfunction.

The Redragon configuration program is used with a wired connection or via 2.4 GHz. If K688SP types normally over Bluetooth but the program reports that the device was not found:

1. Close Redragon Software.
2. Switch the keyboard to USB-C or 2.4 GHz.
3. Wait for Windows to detect the device in the new mode.
4. Test normal text input.
5. Launch the program again.

Do not remove a working Bluetooth driver just because the proprietary program does not work via Bluetooth.

Official Redragon K688SP-RGB-PRO software

K688SP-RGB-PRO uses software package version 2.0.

The following names appear on official pages:

Redragon_K688-RGB-PRO_Setup_v2.0_20240715.exe

and:

Redragon_K688-RGB-PRO_Software.exe

The verified files for K688SP are completely identical to each other.

Moreover, verification showed that this is the same binary software package that Redragon provides for K688GB-RGB-PRO.

Where to download the program

Use the official Redragon catalog:

Redragon software

In the list, select specifically Redragon K688SP-RGB-PRO Gaming Keyboard.

Do not download software based only on the word K688 from an unknown website.

K688SP and K688GB use the same program — do you need to install both?

No. The verified K688SP and K688GB installers have identical contents.

If the correct version 2.0 program is already installed and it detects K688SP-RGB-PRO, there is no need to install a second file with a different name.

Reinstalling the identical package will not add new functions.

What the program is used for

The Redragon program is used for additional settings, including:

• assigning supported keys;
• creating and editing macros;
• configuring RGB lighting;
• saving available software settings.

The exact names of tabs and functions may depend on the program interface version.

Installing the program in Windows 11

Windows shows a warning when launching the EXE file

The verified installer may not appear in Windows as an application with a standard digital signature from a verified publisher. Therefore, Microsoft Defender SmartScreen or another system protection feature may display an additional warning.

Do not disable Microsoft Defender, SmartScreen, or antivirus protection just to install the keyboard program.

Instead:

1. check that the installer was obtained from the official Redragon website;
2. make sure the K688SP-RGB-PRO page was opened;
3. do not run similar files from unknown websites;
4. do not install firmware for another model to work around the problem.

The program shows Device not detected

If the keyboard works but the program does not detect it:

1. Check the connection mode.
2. If Bluetooth is being used, switch to USB-C or 2.4 GHz.
3. Close Redragon Software.
4. Wait a few seconds.
5. Test normal text input.
6. Launch the program again.

If this does not help:

1. Connect the keyboard directly to the computer with the cable.
2. Try another USB port.
3. Close Redragon programs for other devices.
4. Check that the official version 2.0 package is being used.
5. Restart the program.

Windows detects the keyboard, but Redragon Software does not

If K688SP types, Windows is already communicating with it through the HID driver.

In this situation, you should not immediately remove system devices. First check:

• the connection mode;
• whether the correct package is installed;
• the USB port;
• operation through a wired connection;
• whether Redragon programs for other keyboards are running at the same time.

How to reinstall the program in Windows 11

1. Open Settings → Apps → Installed apps.
2. Find the Redragon program.
3. Click the three-dot button.
4. Select Uninstall.
5. Restart the computer.
6. Connect K688SP-RGB-PRO via USB-C.
7. Check normal keyboard operation.
8. Download the program again from the official K688SP page.
9. Repeat the installation.

How to reinstall the program in Windows 10

1. Open Settings → Apps → Apps & features.
2. Find the Redragon program.
3. Select it and click Uninstall.
4. Restart the computer.
5. Connect the keyboard via USB.
6. Install the official package again.

How to safely test setting changes

After installing the program, it is not recommended to immediately change a large number of settings.

1. Change only one setting.
2. Apply the change.
3. Check the result.
4. Close the program.
5. Check the keyboard again.
6. Only then proceed to other settings.

This makes it easier to determine the cause of a problem if the keys or lighting begin working incorrectly after configuration.

Configuring programmable keys

If you need to change the assignment of a supported key:

1. Launch Redragon Software via USB or 2.4 GHz.
2. Select the required key in the program interface.
3. Select an available action.
4. Apply the change.
5. Test the key in a normal application.

For the first test, choose a key whose original assignment can easily be restored.

Configuring macros

To test macros, first create a short sequence.

1. Open the macro editor.
2. Create a new macro.
3. Record several simple key presses.
4. If necessary, configure the available delays.
5. Assign the macro to a supported key.
6. Apply the setting.
7. Test the macro in a text editor or another safe application.

Only after this should you create more complex sequences.

Keys work incorrectly after configuration

If the problem appeared after reassignment or creating a macro:

1. Connect the keyboard via USB.
2. Launch the correct K688SP program.
3. Find the recently changed assignment.
4. Delete or disable the problematic macro.
5. Restore the key’s standard function if such a command is available.
6. Apply the changes.
7. Test the keyboard in a text editor.

RGB settings are not saved

You should not assume in advance that every software setting is necessarily stored in the keyboard’s internal memory.

Check the setting as follows:

1. Change the RGB setting.
2. Apply it in the program.
3. Close Redragon Software.
4. Check the lighting.
5. Turn the keyboard off and back on.
6. Check whether the result was preserved.

If a setting works only while the program is running, this may be a characteristic of the specific function rather than a HID driver malfunction.

The wireless connection drops intermittently

If 2.4 GHz or Bluetooth is unstable, first rule out simple causes:

• low battery level;
• long distance from the computer;
• the USB receiver is connected through a hub;
• radio interference;
• a problematic USB port;
• a conflict with an old Bluetooth pairing.

For troubleshooting, connect K688SP-RGB-PRO by cable. If it works reliably via USB, the problem does not appear to be related to a fault with the main keys or the standard Windows driver.

Key presses are missed or incorrect input appears

If characters are occasionally missed, unexpected actions occur, or the keyboard briefly stops responding:

1. Test wired mode.
2. Disable created macros and custom assignments.
3. Test input in a normal text editor.
4. If everything works correctly over USB, test 2.4 GHz and Bluetooth separately.
5. Test the keyboard on another computer.

This helps determine whether the problem is related to software configuration, the wireless connection, or the key itself.

Problems appeared after installing another Redragon program

If software for another K688 model or another Redragon keyboard was previously installed:

1. Uninstall the unsuitable program.
2. Restart Windows.
3. Test K688SP without additional software.
4. Download the program from the official K688SP-RGB-PRO page.
5. Install only the verified version 2.0 package.

How to check the keyboard in Windows 11

1. Right-click the Start button.
2. Select Device Manager.
3. Check Keyboards.
4. Check Human Interface Devices.
5. If there is a Bluetooth problem, also check Bluetooth.

K688SP may appear under a standard system HID keyboard name. The absence of the word Redragon in the name is not an error by itself.

How to check the keyboard in Windows 10

1. Right-click the Start button.
2. Open Device Manager.
3. Check Keyboards and Human Interface Devices.
4. When using Bluetooth, check Bluetooth.

If text input works and there are no warning icons, there is usually no need to look for a separate system driver.

A yellow icon appears in Device Manager

If you have determined that the error belongs specifically to K688SP-RGB-PRO:

1. Disconnect the keyboard.
2. Open Device Manager.
3. Find the related device with the warning icon.
4. Right-click it.
5. Select Uninstall device.
6. Restart the computer.
7. Connect the keyboard via USB-C.
8. Wait for Windows to detect the device again.

If the keyboard does not work at all

For initial troubleshooting, use a wired connection.

1. Connect K688SP-RGB-PRO with a USB-C cable.
2. Try another USB port.
3. Try another known-good cable that supports data transfer.
4. Allow the battery to charge.
5. Restart the computer.
6. Test the keyboard on another computer.

If the device works via USB, troubleshoot 2.4 GHz and Bluetooth separately.

If K688SP is not detected even via USB on another computer, installing another Redragon program usually does not solve this problem.

Can K688SP-RGB-PRO be used without the Redragon program?

Yes. The proprietary software is not required for normal text input.

The keyboard can be used via USB-C, 2.4 GHz, and Bluetooth through standard operating system features.

Redragon Software version 2.0 is worth installing when programmable functions, macros, or additional RGB settings are required.
