Thank you for your reply ESP_Sun.

If I understand your reply correctly, then:-

BT Sink -> I2S Master
BT Source -> No I2S

If BT Source has no I2S, how do I give it the audio?

Kind regards
Pedro

Hi ESP_Sun, I tried the +BTA2DPSRC command as per your example, but if didn't work. These are the commands I sent:- AT+CWMODE=1 OK AT+CWJAP=<ssid>,<pw> WIFI CONNECTED WIFI GOT IP OK AT+BTINIT=1 OK AT+BTA2DPINIT=1 OK AT+BTA2DPCONN=0,<bt address> OK +BTA2DPCONN:0,<bt address> AT+BTA2DPSRC=0,"http://xx...

Thank you again for your reply ESP_Sun.

That's cool. I'm busy on another project at the minute, but I'm keen to try that out in a couple of days...

Kind regards

Thank you for your reply ESP_Sun. When you say "opposite end" do you mean BT Sink? Therefore, I assume the AT+BTA2DPSRC command is given to the BT Source end, is that correct? If the command is:- AT+BTA2DPSRC=0,"http://somesite/music.mp3" how does it get the music.mp3? Does it switch to WiFi? Does r...

Hi Arnaud,

Have you found what you are looking for?

I have some code written in C, interrupt driven, for the STM32 microprocessor. But could be adapted to any microprocessor.

PM me if you what to discuss further.

Kind regards

Hi all,

I have a couple of questions about A2DP.

Using a ESP32 with AT, I have enabled A2DP support, which gives 3 I2S pins. My questions are -

1) is the I2S a master or slave?

2) What difference will the +BTA2DPINIT sink or source make to the I2S function?

Thanking you
Pedro

Hi all,

I am new to Esp32, although I have been working with electronics for many years.

I see that the ESP32 has a AT+BTA2DPSRC command - could someone please tell me what this does, and how to use it?

Thanking you
Pedro
