Yes! Here's how:
Before you start, make sure your projector has completed initialization setup, and your Roku account is logged in and activated.
Go to Home screen> “Settings” > “Remotes & device” > Smartphones & Tablets > + Add New Smartphones & Tablets.
On your device, open the Bluetooth list, find the projector model (e.g., C2R), and pair it.
The projector features Bluetooth 5.2 with A2DP support for enhanced audio.
