    Hello everyone.

    I have to create a simple PCB prototype that can except bluetooth audio signal and play it.

    My idea for now is to have Android phone on one side and PCB with bluetooth chip on the other side.

    I'm looking for advices for creating PCB prototype. It has to have:
    1. a bluetooth connection compatible with Android phones
    2. speaker input to play music that will be send from Android phone or build in speaker

    Any advice is very welcome!

    Hi,

    OK.
    Then choose one of the famous bluetooth audio ICs.
    Read datasheets, read application notes, look for reference designs...and start your own design.

    The priority in my project should be simplicity and energy efficiency.

    Hi,

    please do a little research on your own. You said "It has to be my own product" --> then do so.

    Whether bluetooth audio transmitter and bluetooth audio receiver are compatible or not depends (mainly) on the used protocol.
    --> Look what the transmitter and reciver support.

    Thank You very much for answer.

    I did research a bit and from my point of view, it would be possible choices:
    1. http://ww1.microchip.com/downloads/e..._DataSheet.pdf

    2. http://ww1.microchip.com/downloads/e..._DataSheet.pdf

    Is this good choice in Your opinion?

    Re: Mobile Phone to PCB via bluetooth - prototype

    Hi,

    I recommended to use a "famous bluetooth IC".
    But Iīve never heared before about the two you selected.
    Why did you choose them?
    Why mono?

    They may be the best for you - I donīt know, because I donīt know your requirements/specifications.
