What to Do If the WH851 Bluetooth Won't Connect

If your GAOMON WH851 pen tablet fails to connect via Bluetooth, follow the steps below in order. These solutions address the most common causes of connection failure.

1. Remove the Previous Pairing Record and Re-Pair
   Before attempting a new connection, you must clear any old or failed pairing records on your computer.
   1. Open your computer's Bluetooth settings.
   2. Find the WH851 in the list of paired devices.
   3. Select "Remove device" or "Forget" to delete the old record.
   4. Turn off the tablet, then turn it back on.
   5. Re-enable Bluetooth on your computer and pair with the WH851 again.
   6. The tablet's blue light will flash when it is turned on, indicating it is ready to pair.
2. Force Bluetooth Pairing Mode (Reset Button)
   If the tablet does not appear in your computer's Bluetooth list, you may need to force it into pairing mode using the reset button.
   1. Locate the small Reset button on the back of the WH851 tablet.
   2. Use a pointed object (such as a paperclip or pen tip) to press and hold the Reset button for 3 seconds.
   3. This will enable Bluetooth pairing mode, and the tablet should now be discoverable.
3. Check Bluetooth Range and Interference
   1. Ensure your computer and the WH851 tablet are within 10 meters (about 33 feet) of each other.
   2. Move away from other wireless devices (routers, microwaves, USB 3.0 hubs) that may cause interference.
   3. Try connecting in a different location to rule out environmental interference.
4. Update Your Computer's Bluetooth Driver
   An outdated or corrupted Bluetooth driver is a common cause of connection issues.
   1. Open Device Manager on Windows.
   2. Expand the Bluetooth category.
   3. Right-click your Bluetooth adapter and select "Update driver".
   4. Choose "Search automatically for drivers" and follow the prompts.
   5. If no update is found, visit your computer manufacturer's website to download the latest Bluetooth driver for your model.
5. Install or Update the GAOMON WH851 Driver
   The GAOMON driver is required for the tablet to function correctly. If it is not installed or is out of date, the Bluetooth connection may fail.
   1. Download the latest driver from the official GAOMON website: www.gaomon.net/download.
   2. Before installing, uninstall any previous GAOMON driver and close all graphics software and antivirus programs.
   3. After installation, a grey driver icon will appear in your system tray. When the tablet is connected, the icon turns orange, indicating the driver has recognized the tablet.
6. Verify Operating System Compatibility
   The WH851 supports the following operating systems via Bluetooth:
   1. Windows 7 or later
   2. macOS 10.12 or later
   3. Android 6.0 or later (for Android phone/tablet connection)
      * Ensure your device meets these requirements.
7. Additional Tips
   1. If the tablet still won't connect, restart both your computer and the tablet.
   2. Disconnect any other Bluetooth devices that may be interfering.
   3. Try connecting the tablet via a USB-C cable first to confirm the tablet itself is functioning, then switch back to Bluetooth.
