Microphone Deployment on Fin

Hi all,

I am trying to deploy a microphone on Balena Fin to record the sound and save to both:

  1. the on board storage
  2. the local computer desktop remotely

How can I achieve that? I am currently on the step of successfully recording the sound but cannot save.

When you run your balena application there will be a /data folder in the container which is used for persistent storage. For more information please check the following section: https://www.balena.io/docs/learn/develop/runtime/#persistent-storage

As for storing data remotely one idea could be to run an FTP (or similar) server on the desktop computer and upload the data there with an FTP client.

@majorz Thanks for your reply. If I use a external storage device connected with Fin, how can I store the recorded audio files from microphone to the external storage on Fin? Is there any instructions?

Hi Xia. Yes, here is the documentation about this: https://www.balena.io/docs/learn/develop/runtime/#mounting-external-storage-media
