Audio data using Data forwarder

#1

I am using a development board (PSoC6) which is not yet supported by Edge Impulse. I am able to generate 16bit PCM at 16KHz sample rate from a PDM mic. I wanted to know what is the format (hex? little endian?) or way to stream the PCM data over serial to use with Data Forwarder. I could not find any example to relay audio data using Data forwarder.

Hi @naveen, audio goes too fast for the data forwarder to be captured. If you have PCM data already then turning it into a WAV file and uploading with the uploader is the easiest.
