Bluetooth A2DP Source example? (ESP32 streaming to BT speaker)

Postby fesp32@joov.de » Wed Jun 14, 2017 1:29 pm

Hi,

I understand that the ESP32 uses the Bluedroid Stack which apparently supports A2DP Source and Sink services (please correct me if this is wrong).

The esp-idf contains an a2dp_sink example which works.

If have the following questions:
- Can the ESP32 also act as an audio source, i.e. A2DP Source?
- Is there any example of that? I am looking at the Bluedroid APIs but I do not have the slightest clue how to configure the ESP32 as an A2DP Source.
- Blue sky question: Is the ESP32 able to connect to two separate Bluetooth Speakers and stream audio to them? Is this doable using the Blueddroid stack?

Any hints welcome.

Cheers,
Johannes

hi johannes

(transceiver) (A2DP-SRC: Advanced Audio Distribution Source)
(receiver) (A2DP-SNK: Advanced Audio Distribution Sink)

what we have just in time as example is A2DP-SNK as ESP_SPEAKER

what you search is A2DP-SRC , i think there is just in time no example available.

best wishes

There may be no example, but is it able to be done?

I stumbled upon this:

https://github.com/gtalusan/esp-idf/tre ... 2dp_source

Never tested but author says it is an implementation of A2DP-SRC
