Connect from phone to esp32 and after A2DPsource

[dandandan1983]

Hello. Maybe it's a strange question because i don't understand something in your library.

I use ESP32 WROOM-32. I want to read data from microphone -> A2DP Source -> Mobil Phone.

I catch issue. I can't connect from phone to ESP32. My phone can't see ESP32 Bluetooth module.
If i used A2DP Sink, i can connect to bluetooth by Phone but i can't write sounds to phone. Or i don't know how to do it.
Is it possible to start connection from Phone, not from Bluetooth module then i use A2DP Source ?

For example. https://github.com/pschatzmann/ESP32-A2DP/blob/main/examples/bt_music_sender/bt_music_sender.ino
My phone didn't see this bluetooth point: LEXON MINO L.
a2dp_source.start("LEXON MINO L", get_data_frames);
I want to have ability for connection from the Phone if it possible. I want to see a point from Phone, connect to it and start receiving audio data.
Is it possible? Thank you for your library.

p.s.
If i change it like my phone name, nothing happens.

This has nothing to do with my library.
As far as I now, mobile phones can not be used as A2DP Sink (Bluetooth Speaker)!
Or have you ever been able to send Audio from one phone to another via A2DP ?

Before your unswer i thought that all Phones use A2DP for that. I thought that i can do my own system like headphones.
Thank you for your answer.
