Is it possible to access content from my NAS or from the SSD in my Rose RS291e unit from the Rose Hifi mobil app?
Yes, through the RoseConnect app, you can play music from the RS201’s built-in SSD or a wirelessly connected NAS.
Ok, can I stream from my NAS to my Phone and then to my Bluetooth attached speakers?
If I understand correctly, you are trying to configure an environment where you can use RS201 and active speakers with built-in Bluetooth?
If so, the configuration you mentioned is not supported.
