I am using esp32 wrover e module on my custom board for the audio development and the development is been done on vs code.
I am also interfacing port expander through I2c for keypad interfacing so I am initializing the port expander before initializing Bluetooth , once if I enable the Bluetooth and initialize the audio pipelines for audio output through Bluetooth earphone then again I cant able to read the port expander. Basically I want to change the audio on key press. Below are the errors occurring.
E (2709) i2c: i2c driver install error
