Low pass filter in nrf5832

[suvarna_kadam]

Hi

I am using nrf52832 dk and nrf52 thingy for development. I am transferring audio data over BLE, but because of surrounding noise issue I want to implement low pass filter for audio data so is there any reference code or any application note for the same?

Hi, 

Unfortunately, there is nothing like that on our side.

That would be exactly the same on an nRF52 as on any other Cortex-M4F - so google general solutions ...

CMSIS DSP would seem an obvious place to start:
