Sound Asset OTA

Example application that demonstrates delivering sound samples to Particle devices using Asset OTA.

Overview Image

How It Works

At a high level, the example does the following:

You use Asset OTA to bundle sound samples along with your application binary
Upon receiving the samples, the Particle device will copy them to an external SD card
Playback control of the audio files is done over the Particle Console

Required Hardware
To follow along you'll need the following hardware:
A Feather-based Particle module (Argon, Boron, Photon 2)
Adafruit Music Maker FeatherWing (pictured is the w/Amp variant)
A speaker (can be either 4Ω 3W or 8Ω 1W)
A microSD card (FAT16/FAT32 formatted)
Optional: a FeatherWing Doubler simplifies wiring (but requires soldering)
