Projecting cannot be done via a Bluetooth connection. Bluetooth bandwidth is insufficient for video and screen mirroring. Bluetooth connectivity is included on some Miroir projector models (such as the M200A and M300A) for flexible connectivity options for devices like external speakers, Bluetooth keyboards and for the Miroir Remote.
If you would like to project wirelessly, we offer a few models that do have this feature. Information on projecting wirelessly can be found in the Project Wirelessly help center article.
