Issue description
- If your Inline Fan 2 (IF2) is experiencing an unexpected Bluetooth disconnection, please refer to this guide for troubleshooting.
Possible causes
- Incompatible Device Model: The laser engraving machine may not support Bluetooth connectivity.
- Improper Bluetooth Dongle Installation: The device's Bluetooth dongle may not be securely connected.
- Excessive Distance: The distance between devices exceeds the Bluetooth connection range.
- Damaged Bluetooth Dongle: The dongle itself may malfunction.
Troubleshooting
Step 1: Check compatibility
Ensure that your xTool laser engraver supports Bluetooth connection with the IF2. The compatible models include:
Note that the P2 model cannot connect to the IF2 via Bluetooth dongle.
Disengage AUTO Mode: If your laser machine does not support Bluetooth dong connection, please disengage IF2's "AUTO" mode by tapping the "Airflow down" or "Airflow up" buttons to operate the fan manually.
If this does not resolve the issue, proceed to the next troubleshooting step.

Step 2: Check Bluetooth dongle connection
- Ensure that the Bluetooth dongle is properly inserted into the appropriate port on the laser device.
- Inspect that you are using the correct port on your laser machine.
- Ensure that the dongle is firmly and fully seated in place.
- If the issue persists, proceed to the next step.

Step 3: Check the distance
- Ensure that the distance between your laser device (connected to the Bluetooth dongle) and Inline Fan 2 is less than 5 meters.
- If it exceeds this distance, it may compromise Bluetooth communication. Move the fan 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.
