I'm not sure if this is possible..

If a phone's pinout is TRRS it means it can take analogue audio input through the 3.5 audio jack. Right?

Is it possible to convert this audio input to digital output through A2DP Bluetooth profile?

There is Bluetooth transmitter devices out there I know but it would be more convenient if there is an app that could do that.

Imagine you could hook your phone to TV with a 2 way 3.5 audio jacks cable, watch TV, but listen to the sound streamed via your phone, with your Bluetooth headset.
