The projector supports the Bluetooth 5.0 connection, but it does not allow direct connection to an iPhone via Bluetooth for screen projection or control. External Bluetooth speakers or headsets can be connected, but Bluetooth connection with a mobile phone is not supported for direct video or audio transmission from the phone. For screen mirroring with an iPhone, you need to use functions such as AirPlay or Miracast via WiFi, but some applications may not be compatible.
