Audio transmission from microphone to smartdevice using nRF52840

[Bluetoothy]

Hi there. I am working on an application where i need to transfer audio signal from a microphone connected to the nRF52840 to a smartphone. Are there any working examples demonstrating this? Or is it totally impossible to do on this BLE module?

Which also brings the next question up, is Bluetooth LE Audio around the corner?

The nRF52840 has both I2S — Inter-IC sound interface and PDM — Pulse density modulation interface peripherals.

The finalization of LE Audio specification is scheduled for Q4 2020 I think, we'll have a demo ready.

Hi haakansh. Thanks for the reply. I already use the SoC with a microphone. That is not really the challenge. What i am seeking is information about transmitting audio signal from the microphone through BLE.

So a good portion of patience is needed. Is it realistic to expect anything to be ready by Q1 2021?
