I'm trying to implement a Bluetooth microphone.  I'd like to use a external digital microphone (output PDM) combine it with a MCU + Bluetooth chip (needs a PDM input) and send/stream the recording to a smartphone via Bluetooth, so I can listen to the recorded sound.

Which chip would you recommend for such a audio application?

Thank you in advance, BR

Hi  @HTerm1 

Our Bluetooth dual mode chips supports only I2S / PCM interface to use A2DP/HFP profiles for audio streaming. CYW20721 is the recommended one for Audio products. 

We do have a PSoC 6 MCU which supports PDM microphone interface.  

Regards,
Anjana
