The custom addon allows you to upgrade on the air (OTA) the Arduino firmware connected to the RPi via USB
It’s an add-on for those who:
- installed Hassio https://www.home-assistant.io/hassio/installation/ on Raspberry Pi (or compatible)
- connected Arduino (or many other microcontrollers supported by AVRDUDE http://savannah.nongnu.org/projects/avrdude) to RPi via USB
- wants to reflash Arduino on the air.
The task can be divided into stages:
- on “big PC” compile source code, for example using Arduino IDE
- transfer compiled binary hex-file to RPi
- install and run the add-on and Arduino will start in seconds the updated program.
