- Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth for cleaning. Avoid liquids or abrasive cleaners.
6. Troubleshooting
If you encounter issues with your WIDI Bud Pro, refer to the following common problems and solutions:
- Device Not Connecting/Pairing:
- Ensure the WIDI Bud Pro is properly plugged into a powered USB port.
- Crucially, general Bluetooth pairing does not work for Bluetooth MIDI. Always use the WIDI App for initial setup and pairing, or follow specific instructions for your operating system.
- Update the firmware via the WIDI App. Outdated firmware can cause connectivity issues.
- Temporarily disable or delete other Bluetooth profiles on your host device (computer/mobile) before attempting to connect the WIDI Bud Pro.
- Intermittent Connection or Ghost Notes:
- Check the distance between the WIDI Bud Pro and the connected MIDI device. While rated for 65ft, environmental factors can reduce range.
- Minimize interference from other wireless devices (Wi-Fi routers, other Bluetooth devices).
- Ensure the WIDI Bud Pro has a clear line of sight to the other WIDI device or host.
- If using with Android, ensure you have a compatible Bluetooth MIDI app installed (e.g., "Bluetooth MIDI Connect" or "MIDI+BTLE") and that your music application supports external Bluetooth MIDI devices.
- Resetting the Device:
- Terminate Existing Connections: When the device is switched ON, press and hold the button for 3 seconds to terminate all existing connections and activate peripheral mode.
- Factory Reset: When the device is switched OFF, press and hold the button while switching it ON. Continue holding until the LED flashes 3 times, then release it to return to factory settings.
