I have just read through the operating instructions.
Bluetooth is only described as an input source.
Only the network and headphone connections are described as outputs.
I could not find out from the WIKI whether Bluetooth recognises via the reception protocol whether it has to send or receive.

No. I don't think so. The Bluetooth signal does not go out. In any case, it didn't work with my Bluetooth headphones (Marshall and Philips). However, the connection via Bluetooth with my iPad and mobile phone (Android and iOS) works flawlessly.

As far as I can see or have used Bluetoth, you can only play music on the radio from a device such as an iPhone via Bluetooth. I don't think the Bluetooth signal goes out to your headphones. Greetings, sven
