# Bluetooth connection troubleshooting * If your Windows PC does not have a BTLE driver built in, you will need a BTLE adaptor to connect your headset to your PC via Bluetooth. ‌ * On Windows, when your headset is connected to Bluetooth it will show as connected in the Bluetooth settings window. It should then be available to connect to in EmotivPRO. * If your headset is already paired to your computer, power cycle the headset to reconnect it to your device. * If your headset is showing as connected to your device, but you still cannot connect it to EmotivPRO or Cortex API, remove the headset from the Bluetooth & other devices devices list, but keep your headset turned on. * Make sure that your headset’s battery is fully charged before connecting it via Bluetooth. * Bluetooth shares a 2.4 GHz ISM band with other household devices, such as cordless telephones, wireless networks, baby monitors, and microwave ovens. Avoid using your headset near common sources of interference, such as power cables, microwave ovens, fluorescent lights, wireless video cameras, and cordless phones. * If you are experiencing connection issues with your headset that you suspect might be due to frequency congestion, see[ AirPort and Bluetooth: Potential sources of wireless interference](https://support.apple.com/en-us/HT201542) for further information. * If your headset and Bluetooth are not connecting with each other, move them closer together to see if it improves the connection. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
