Actually, I have a spare android phone which is connected to my old speaker system. I wanted to connect to that phone via Bluetooth as if I'm connected to a Bluetooth speaker. So that, I can route audio to the speakers using any device connected to that spare phone (Indirectly giving the Bluetooth functionality to the old speaker system)
Edit: I saw the related questions, those questions needed any working method that solves it. I don't want to use any third-party app like a music player or anything. I just want the spare android phone to be connected as an audio source to my phone.
The first image is the screenshot of a Bluetooth headphone connected to my phone. I want the same settings as "Media Audio" when I'm connected to spare android phone.
The second image is the screenshot of Bluetooth settings when connected to the android phone which is currently being detected as a phone and I want that to be shown as a Bluetooth Audio device.
