Can I use the Tidal app for streaming with node 2 without Bluesound app?

Ok now I get it. Bummer - I like the concept of "radio stations" and "Daily Mix" that both Spotify and Tidal offer on their Apps. As far as I discovered so far, Bluesound is much more basic than these sites. Need to reconsider the design-up to Tidal.

@arafiq : It was my understanding that the node 2 and the iPad have to be connected to the same WiFi network. The node2 streams via WiFi or LAN and Bluetooth between Node 2 and the iPad is used as a GUI/navigation aid similar to a remote control. Am I wrong? Your description sounds as if the streaming "receiver" is the iPad and the iPad is sending the signal to the node2 via Bluetooth. Strange...?

I finally figured it out how to connect without BT - Thanks! 
@djones51: I believe you are correct with the Bluetooth down sampling but at first listening I do not hear such a big difference so perhaps convenience is worth the small loss?

I guess I figured it out - sorry for that: In the Bluesound App I used the left navigation button and pressed “Bluetooth” to connect my iPad with the node 2. Is that the correct way of doing it?

Ok, but if I do not press “Bluetooth” I  can not use the Tidal App. I also have a WiFi connection between the iPad and the node. I was under the impression that the node streams straight from it’s own WiFi connection to my router and that the iPad is used as a GUI via Bluetooth connection with the node. Or not? This is quite confusing to me, sorry

Yes I get that but then I am streaming using the navigation of the Bluesound app and not the Tidal App, correct?
