Is it possible to transfer a digital microphone data over ble

Hi

I am using digital microphone with nrf52832 dk using PDM library for interfacing

I am referring  nRF thingy for firmware development, sound service is successfully developed but device fails to start microphone.

For PDM library I referred following link which makes me confuse.

Here he mentioned don't advertise while PDM working.

So Please clear this confusion.
