Libraries competing for I2S?

[renatoianhez]

With the new version of the ESP32-Arduino IDE, there was a change in the I2S API, and consequently some libraries were affected. One of them that I use is pschatzmann's Bluetooth A2DP. On this version of my webradio I use it to transform it into a bluetooth receiver speaker. However, updating that library seems to conflict with your ESP32-audioI2S library, since, even in exclusive programming blocks, the Bluetooth library does not work. However, the A2DP works in an example sketch. Is there a "competition" for I2S in this case?

That may be, in V3 there is a handle on I2S. A double initialisation could lead to an error. You can create an audioI2S object as a reference.

Audio* audio = new(Audio);
audio->setPinout(1,2,3);
audio->connecttoFS(SD_MMC, "/mySong.mp3");
....

delete audio;
....

BT* bt = new(BT);

You can destroy the object and thus release I2S. You can then create a Bluetooth object.

Oh! Thank you! I will test something similar!
