Can I pass data from other device through serial to nrf52840-dk board for keyword spotting exmaple

I am doing keyword spotting with nrf52840-dk board by pdm mic
I have successfully run this model on nrf board
But Can I pass data through serial to nrf board for inference without use of mic . Is it possible that I take input from other board and pass data to nrf board for inference ?
Is there any feature in keyword spotting firmware
thanks for the help

I don’t see why this couldn’t be done. The other device must capture the mic data and pass the buffered data in the same format as what is being captured from the mic now. I’d have to see the current code to be able to advise any further.


Thanks for the reply

Please let me know for any update ?

Hi @aayushi.kanojiya,

As @MMarcial mentioned, this should be possible. You will need to make sure that your serial connection can handle the sample rate of your audio recording. Additionally, you will likely need to find ways to capture audio → transmit over serial → buffer → perform inference.
