Hi Team，

I have a customer who would like to drive a PDM interface Digital microphone( two wired) with CC2640R2!

Does CC2640R2 support PDM interface to drive it？ I saw CC2650RC can support it and I found the demo on our SDK. Does CC2640R2 have this demo too?

Thank you!

Hi Eggsy,

CC2640R2F supports PDM exactly as CC2650. The demo is not ported to CC2640R2F, but could be used as a reference.

Regards,
Fredrik

Hi Fredrik,

Thank you! Do we have a plan to ported it to CC2640R2F? There are more and more customers focusing on voice via BLE for Voice Recognition!

Regards,
Eggsy

Hi Eggsy,

There is no plan to make a full port of the example. The PDM code itself should be very easy to move to CC2640R2F though.

Cheers,
Fredrik

Hi Fredrik,

Thank you! One more question, If running this voice demo, can CC2650RC use Audio Profile Service to communicate with a central device which only support BLE4.0 ?
