I have a Sonos Era 100 and I am trying to get it to receive audio from a bluetooth transmitter (Avantree Oasis .

ie basically the Sonos Era is going to be receiving an external audio source via bluetooth.

Can anyone advise if / how this can work?

When attempting to pair the devices, I cannot see anything in the Sonos app.

Does the Era 100 even support this?

My backup solution is to connect another third party bluetooth receiver to the Avantree, then send the signal via aux cable to the Line In on the Sonos Era.
