6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery. | Charge the device fully. |
| Cannot pair with a Bluetooth device. | Device not in pairing mode; Bluetooth device too far; Interference; Already connected to another device. | Ensure B101 is in pairing mode (flashing light). Move devices closer. Turn off other Bluetooth devices. Disconnect from previous connections. |
| No sound or poor sound quality. | Incorrect mode (TX/RX); Cables not fully inserted; Volume too low; Source device issue. | Verify TX/RX mode is correct. Ensure 3.5mm cables are securely connected. Adjust volume on both B101 and connected devices. Test with another audio source. |
| Audio delay (latency) in TX mode. | Connected headphones/speakers do not support aptX Low Latency. | For optimal low latency, ensure both the B101 and your receiving Bluetooth device (headphones/speakers) support aptX Low Latency or aptX Adaptive. Note: This adapter is not recommended for use with musical instruments or live music due to potential noticeable delays. |
| Dual-link connection fails. | Second device not in pairing mode; Compatibility issues. | Ensure the second Bluetooth device is in pairing mode before attempting to connect. Some devices may have limited dual-link compatibility. |
