Hello, I have several development-related questions about the microphone functionality of the NRF5340 AUDIO DK in headset mode:
- Is it possible to configure the device as a microphone-only LE Audio headset using the available configurations?
- How can I integrate and use a custom I2S microphone, such as the Adafruit ICS43434 MEMS, with the NRF5340 AUDIO DK?
- Can the "Line In" input be used as a microphone input while in headset mode? If so, what code modifications would be necessary to enable this functionality?
- I have the device successfully connected to a Google Pixel 9, and it works perfectly for general audio, but I am unable to use the microphone as an LE Audio input while simultaneously outputting Bluetooth audio to another pair of headphones. Is there a way to achieve this?
- Ultimately, I aim to create a high-quality microphone solution using the NRF5340 AUDIO DK. What would be the best approach to accomplish this?
Any guidance or recommendations would be greatly appreciated!
