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
AT+BTA2DPSRC
Re: AT+BTA2DPSRC
Hi,
The AT+BTA2DPSRC command is to get the music resource and give it to the opposite end. The opposite end can play the music. When using this command, you need to establish a connection with the opposite end.
Hope this helps you.

Re: AT+BTA2DPSRC
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 require Ethernet?
Thanking you

Re: AT+BTA2DPSRC
Yes, your understanding is absolutely correct. "opposite end" refers to BT Sink. AT+BTA2DPSRC command is used for BT Source. You can read the AT command sequence to use this feature.
Code: Select all
AT+CWMODE=1
AT+CWJAP="MERCURY_2414",""
AT+BTINIT=1
AT+BTA2DPINIT=1
AT+BTA2DPCONN=<conn_index>,<remote_address>
AT+BTA2DPSRC=0,"https://dl.espressif.com/dl/audio/ff-16b-2c-44100hz.mp3"
AT+BTA2DPCTRL=0,1

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
Pedro

Re: AT+BTA2DPSRC
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://xxx.xxx.xxx.xxx:portnumber/musicfolder/musicfile.mp3"
OK
AT+BTA2DPCTRL=0,1
OK
When I didn't hear anything, I checked my server logs - there was no attempt to contact it for the musicfile.mp3.
Do you have any suggestions on what went wrong?
Is there a command to check the playing progress, or whether it is still playing?
Kind regards
Pedro
