If you're utilizing the BlueOs via a phone (apple or android) or tablet to control your Node and the source is Tidal, you aren't using bluetooth if everything is connected to your wi-fi network. The only way you would be using bluetooth is if you're using Apple Airplay or your Vault isn't connected directly to the internet.
I stream Spotify/Radio Paradise/Tidal on my CXN via the Cambridge StreamMagic app over my wi-fi network. Bluetooth never enters the picture.
