Micro-ROS is an embedded framework allowing you to connect low-power, cheap IoT devices into a ROS 2 system. By using Micro-ROS together with Husarnet peer-to-peer VPN your robot doesn't need to be in the same LAN as an IoT sensor.

Thanks to that your robot can be mobile/5G connected and talk directly with IoT sensors or actuators connected over Wi-Fi. Without any proxy server in between.

In this article I present a ready to use GitHub template for ESP32 Wi-Fi microcontroller allowing you to bring your ROS 2 powered IoT sensors to life in minutes.

GitHub Actions is a mature and extremely popular CI/CD tool. It allows you to create workflows for software deployment, testing, building ... whatever. In GitHub Actions you build your workflows by using blocks automating common tasks called Actions.

One of those building blocks is now Husarnet Action! 🎉

Learn how you can leverage Husarnet Action in your workflow to deploy code to devices with no public IP like laptop, Raspberry Pi, some random VM sitting on your server or even to ESP32 microcontrollers. All by adding a few lines to your existing GitHub Actions yaml file.

There are a lot of examples on the internet about how to perform OTA (Over-The-Air firmware update) to your ESP32 as long as your chip is in the same LAN as your computer.

While Husarnet is basically a VPN software which works not only on your laptop, but also on your ESP32, it's easy to port exisitng OTA examples to work over the Internet. I'll show you how to to that.
