Issue description

• If your Air Purifier 2 (AP2) is experiencing an unexpected Bluetooth disconnection, please refer to this guide for troubleshooting.

Possible causes

1. Signal Interference: External devices may be causing disruption.
2. Improper Bluetooth Dongle Installation: The device's Bluetooth dongle may not be securely connected.
3. Excessive Distance: The distance between devices exceeds the Bluetooth connection range.
4. Damaged Bluetooth Dongle: The dongle itself may malfunction.

Troubleshooting

#1 Check for magnetic interference

• Ensure that no strong electromagnetic devices, such as induction cookers, are in close proximity to the laser engraver (connected to the Bluetooth dongle) and Air Purifier 2.
• Maintain a distance of at least 2 meters from any strong radiation sources to guarantee Bluetooth communication.
• If this does not resolve the issue, proceed to the next step.

#2 Check the Bluetooth dongle connection

• Ensure that the Bluetooth dongle is properly inserted into the appropriate port on the machine.
  • Inspect that you are using the correct port on your laser machine (refer to the images below).
  • Ensure that the dongle is firmly and fully seated in place.

• If the issue persists, proceed to the next step.

#3 Check the distance

• Ensure that the distance between your laser device (connected to the Bluetooth dongle) and Air Purifier 2 is less than 5 meters.
• If it exceeds this distance, it may compromise Bluetooth communication. Move the purifier within 5 meters of the laser device.

If none of these steps resolve the unexpected disconnection issue, the Bluetooth dongle may be malfunctioning. Please contact xTool Customer Service for further assistance.
