10. Troubleshooting

If you encounter issues with your Bomivoi Bluetooth Transmitter Receiver, please refer to the following common problems and solutions:

Problem	Possible Cause & Solution
No power/Device not turning on	Ensure the USB-C cable is securely connected to both the device and a working 5V power adapter/USB port. Try a different power source or cable.
Cannot pair with Bluetooth device	Ensure the device is in the correct TX/RX mode. Make sure your Bluetooth headphones/speaker/phone is in pairing mode. Clear previous pairing information on the Bomivoi device by long pressing the pairing button for 5 seconds. Move the devices closer to each other. Restart both the Bomivoi device and your Bluetooth device.
No sound in TX mode	Verify the audio cable is connected to an output port on your TV/PC, not an input. For TVs, ensure the audio output setting is set to PCM mode. Check volume levels on both the Bomivoi device and your connected Bluetooth headphones/speaker. Ensure the Bluetooth device is successfully paired and connected (solid A/B light).
No sound in RX mode	Verify the audio cable is connected to the input of your wired speaker/stereo. Check volume levels on both the Bomivoi device and your wired speaker/stereo. Ensure your Bluetooth source device (phone/tablet) is successfully paired and playing audio.
Audio delay/latency	If experiencing significant delay, ensure both the Bomivoi device and your Bluetooth headphones/speaker support aptX Low Latency (aptX-LL). If not, the audio will default to a higher latency codec.
Short Bluetooth range/Interference	Reduce obstacles between the Bomivoi device and your Bluetooth device. Avoid placing the device near Wi-Fi routers, microwaves, or other strong signal sources. Ensure the antenna is properly positioned.
