• Cloud Build Setup :

  • Open the Cloud Build page.
  • Enable Cloud Build API if not enabled yet.
  • Select the Triggers tab.
  • Click on Create Trigger.
  • Now you can select your Git repository and authenticate with your provider. I used Github.

  • Click on Create.

• Run on the command line:

./deploy-prod.sh

Upload firmware with PlatfomIO

I recommend installing the Visual Studio Code (VSCode) IDE and the PlatformIO plugin to get started using it. Just follow the step on the link below:

https://platformio.org/platformio-ide

To deploy to the board you can use the “Build” and “Upload” buttons on PlatformIO Toolbar.
