Hello,
I'm designing a device and I only have one problem left, How can I transmit audio (music) from an arduino (or stm32) through a dfplayer via bluetooth to a pair of headphones or speaker. I know that an speacial type of bluetooth is needed but nothing else.

And can I "break" that special bluetooth board (if necessary) and build it my self ( I need it to be as small as possible)?

Thank you in advance!!!

Yes on the board as long as you maintain the RF layout in particular.
Normally designers use the manufacturers layout on their boards, because
vendors have done the certification with FCC.

If you don't want to design/code from scratch hack a USB BLE dongle ....?
Or use one of these boards - https://www.banggood.com/search/bluetooth-audio.html?from=nav

Thank you for responding,
the problem is that I want to transmit audio not receive it, I've found this bluetooth module https://learn.sparkfun.com/tutorials/understanding-the-bc127-bluetooth-module/all which is compatible with a2dp, apparently the type of bluetooth I need.
But I'm not sure if there is another way.

Edit: I've started searching for a2dp bluetooth transmitter and I think that Im into something.
