Deploy PAC/BTI test using a Greengrass thing group

In this section, you’ll use a Greengrass thing group to deploy a set of components, including your PAC/BTI test component, to both Greengrass core devices.

Create the deployment

  1. In the AWS Console, go to IoT Core > Greengrass > Deployments, then select Create.

  1. Name your deployment and select the thing group My_PAC_BTI_Test_Devices, then select Next.

  1. Select the test component that you created in the previous section, as well as default Greengrass components, and then select Next.

  1. After deployment starts, Greengrass installs and prepares the custom component on both PAC/BTI test devices. Wait until the Execution overview shows 2 successful targets.

When both devices show successful deployment, you’re ready to run PAC/BTI tests on each device.

What you’ve accomplished and what’s next

You’ve now created a Greengrass deployment that targeted the thing group containing both PAC/BTI test devices. The deployment installed the PAC/BTI custom component on both the Raspberry Pi 5 and the Jetson Thor devices by following the YAML recipe.

Next, you’ll run PAC/BTI tests on each device using AWS IoT Core MQTT.
