Virtual Devices Overview

The virtual device guide shows you how to build and test your system without any hardware. Take THAT, atoms! Software, FTW!

Virtual devices use the same provisioning steps as any other device, and are a good way to verify you have correctly set the device credentials. They are also a valuable tool in testing the lightDB state and lightDB stream schemas that you plan to use with your hardware.

There are two paths for testing using virtual devices:

• Using the coap command to send virtual responses to the platform
• Using QEMU (an emulator) to act like a piece of hardware would in the real world. QEMU acts as a build target for Zephyr.

This guide assumes you have already completed the Golioth Platform Quickstart.

• The coap virtual device section requires the Golioth Command Line Tools
• The QEMU section requires a provisioned device as outlined in the Golioth Console getting started guide
