When you press the “Bluetooth" button, the projector will stop projecting and switch to Bluetooth speaker mode, which allows you to:
- Use it as a Bluetooth speaker. (the Android TV dongle needs to be updated to the latest version for the smartphone to transmit audio to the projector via Bluetooth).
- Connect it to external Bluetooth speakers or headphones (there will be a minor audio lag -- around 300ms -- which is okay for listening to music but may cause minor latency while watching movies).
*NOTE:
- The Bluetooth function is powered by the QS01 dongle, so please make sure it is installed properly on the projector.
- Other connections such as HDMI do not support Bluetooth.
