Connection Issues

Having trouble connecting your devices? Find solutions to common Bluetooth pairing and connection problems here.

Status Does Not Show ‘Ready to Pair/Connect’

Before you can pair and connect, the app status should display Ready to Pair/Connect.

Why this happens:

Android only allows one app at a time to function as a Bluetooth HID (Human Interface Device). If another app is using this feature, VirtualTablet: Bluetooth cannot work correctly.

Solution:

1. Close any Bluetooth keyboard/mouse apps, even if they’re running in the background
   • Examples: Bluetooth Keyboard & Mouse, Bluetouch, Bluetooth Remote, BT Remote, etc.
2. If the issue persists, some apps don’t properly release Bluetooth HID when closed:
   • Uninstall other Bluetooth input apps, or
   • Restart your device and launch VirtualTablet: Bluetooth first
3. You should now see ‘Ready to Pair/Connect’

Cannot Pair Between Mobile Device and PC

Quick fixes:

• Turn Bluetooth off and on again on both devices, then retry pairing
• Restart both devices and try pairing again

For Windows users - Advanced troubleshooting:

If the above steps don’t work:

1. Open Device Manager
2. Locate and remove the Bluetooth Adapter device
3. Restart your computer (it will reinstall Bluetooth Adapter device)
4. Try pairing again

Connection Failure

For Linux Users

For Ubuntu 25 and newer, you don’t need to do anything - it just works.

But for older Ubuntu releases (20~24), you need to check Bluez configuration.

• Step 1 — Enable HID plugins in BlueZ

  sudo nano /etc/bluetooth/main.conf

  • Add:

    [General]
    Enable=HID
    Experimental=true

• Step 2 — Restart Bluetooth

  sudo systemctl restart bluetooth

• Step 3 — Load HIDP (classic HID) kernel driver

  sudo modprobe hidp

  • Persistent load:

    echo hidp | sudo tee -a /etc/modules

• Step 4 — Repair/pair your device

Connection Timeout

Why this happens:

If you paired your devices before running VirtualTablet: Bluetooth, your PC may not recognize that your mobile device has tablet input capability. The system can only detect this while the VirtualTablet: Bluetooth app is actively running.

Solution:

1. Remove the paired device from both your Android device and PC
2. Launch the app and wait until you see ‘Ready to Pair/Connect’ in the status bar
3. Pair your devices again
4. Try connecting

Connection Successful but Cursor Doesn’t Move

If your devices are connected but the cursor isn’t responding:

1. Remove the paired device from both your Android device and PC
2. Turn Bluetooth off and on for both devices
3. Launch the app and wait until you see ‘Ready to Pair/Connect’ in the status bar
4. Pair your devices again
5. Test cursor movement
