NR5340 AUDIO DK Microphone

O_Hndfrd99

Hello, I have several development-related questions about the microphone functionality of the NRF5340 AUDIO DK in headset mode:

  1. Is it possible to configure the device as a microphone-only LE Audio headset using the available configurations?
  2. How can I integrate and use a custom I2S microphone, such as the Adafruit ICS43434 MEMS, with the NRF5340 AUDIO DK?
  3. 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?
  4. 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?
  5. 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!

    Hi O_Hndfrd99,

    As you are discussing a product idea, I would like to check, do you want to discuss in private, or are you fine with the case being public?

    Regarding your product, I am a little confused. Do you want to create a microphone peripheral for smartphones? Or do you want to create a headset with microphone, supporting bidirectional audio?

    Am I right to understand that you are only interested in one-to-one connection?

    I’m working on a personal project and am happy to discuss it publicly if it can benefit others. The project involves using the NRF5340 AUDIO DK as a microphone. My goal is to send audio captured by the NRF5340 AUDIO DK to my Pixel 9 smartphone and then listen to it through Bluetooth headphones connected to the same device. However, the Pixel only supports connecting one headset device at a time. In this setup, the NRF5340 AUDIO DK would serve as the microphone input while the Bluetooth headphones act as the audio output. I’m facing challenges with routing the audio correctly in this configuration. Is there a way to resolve this issue?

    Additionally, I’m aiming to implement a I2S MEMS microphone on the NRF5340 AUDIO DK or using the ‘LINE IN’ port as the microphone input. Any help or guidance on this would be much appreciated, thankyou.
