I have been trying to edit the code to play multiple sounds, using the push button. But it either mixes up the sound or plays only one sound.
Is there a way to rewrite the code for playing multiple sounds on demand from the SD module?

I would like to use this with a mp3 file instead of a wav file, but I am not sure if it is possible.

Hi,

Thank you for sharing your work! I'm wondering if this code could also work with I2S microphone as a source of data instead of the wav file from SD card? Can continuous streaming of audio possible with this set-up? I'm having a hard time integrating the microphone with the A2DP source code since I'm quite new to this. Any tips/guide?

Thank you very much!!

Warm regards,
rmond

Hi, Schreibfaul

First of all, thanks for your work.

I'm trying to use some custom audios, already on wav but them play fast.

How to generate or convert some audio to play with A2DP?

Give me some direction.

I need some help to change variable
const uint16_t buf_len 1024 to lesser

will it improve the A2DP latency which is currently 1 sec
overall

Hi, I'm trying to compile this sketch with the a2dp into an Mini D1 esp32 board and it's giving me this error....

error: 'ESP_BT_SCAN_MODE_CONNECTABLE_DISCOVERABLE' was not declared in this scope
esp_bt_gap_set_scan_mode(ESP_BT_SCAN_MODE_CONNECTABLE_DISCOVERABLE);
note: suggested alternative: 'ESP_BT_GENERAL_DISCOVERABLE'
esp_bt_gap_set_scan_mode(ESP_BT_SCAN_MODE_CONNECTABLE_DISCOVERABLE);

And when I change for suggested alternative: 'ESP_BT_GENERAL_DISCOVERABLE', it says:

ESP32-A2DP-Source-master\a2dp_source.cpp:574:38: error: 'ESP_BT_SCAN_MODE_DISCOVERABLE' was not declared in this scope
esp_bt_gap_set_scan_mode(ESP_BT_SCAN_MODE_DISCOVERABLE);

esp_bt_gap_set_scan_mode(ESP_BT_SCAN_MODE_DISCOVERABLE);

How can I get this sketch compile?
Thanks a lot.
Great job!

Thanks for your nice source codes.
But I didn't find this software under any license.
Is it possible to provide license such as OSS license to use for everyone?
Please note that you shouldn't add a license if you don't want to make it available to everyone.

Hello,

I tried to conect it to the"Jabra SPEAK 510 USB". No sound. I checked, "parseWAV" works well and the program runs with no problem no error message.
There is no connection to the Jabra device. The name of the Jabra device hat some spaces, could it be the reason for not connecting?
An alternative would be to send the data to my smart phone and from that for the Jabra device?

Thanks!
