I have decided to look at rebuilding my Nvidia Jetson Nano device with the new version of IoT Edge 1.2, as well as taking the opportunity to flash a new 32GB card with a fresh installation of JetPack as the device has become a little messy with my tinkering over the last few months.
Follow the below steps top look at what is involved with getting an IoT Edge device registered and configured with Azure IoT Hub.
Here is my Jetson Nano device OS ready to go, all set up and on the network.
With IoT Edge devices we have two options to register, either with symmetric keys, or with X.509 Certificates. For the purposes of this demo, I will be using the symmetric keys created by the IoT Hub.
In order to run through the registration we have to fist create an IoT Edge device within our IoT Hub in our Azure Subscription.
From your IoT Hub select IoT Edge:
Then click on:
Enter a device ID and click on Save:
We must first do some prereqs which I will run through via ‘ssh’ onto my Jetson Nano:
Prepare device to access the Microsoft Installation packages:
sudo apt install curl curl https://packages.microsoft.com/config/ubuntu/18.04/multiarch/prod.list > ./microsoft-prod.list
Copy the generated list to the sources.list.d directory:
sudo cp ./microsoft-prod.list /etc/apt/sources.list.d/
Install the Microsoft GPG public key:
curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg sudo cp ./microsoft.gpg /etc/apt/trusted.gpg.d/
Install a container engine:
sudo apt-get update sudo apt-get install moby-engine
Install IoT Edge
Update packages and check which versions of IoT Edge and IoT Identity are available
sudo apt-get update apt list -a aziot-edge aziot-identity-service
Install the latest version of IoT Edge and the IoT Identity Service:
sudo apt-get install aziot-edge
Next we will need to provision this device with the symmetric keys created when we registered an IoT Edge device in the IoT Hub earlier.
Create the configuration file by using the template file provided as part of the IoT Edge installation:
sudo cp /etc/aziot/config.toml.edge.template /etc/aziot/config.toml
Open the config file:
sudo apt install nano sudo nano /etc/aziot/config.toml
Scroll to these lines and paste in your connection string from your IoT Edge configuration in Azure Portal:
Exit from nano using ‘Ctrl + x’
Finally apply the config:
sudo iotedge config apply
And there we have it! A configured IoT Edge Device.
We could use some of the following commands to verify our configuration:
sudo iotedge system status sudo iotedge system logs sudo iotedge check sudo iotedge list
Or we could browse to our IoT Edge device in the IoT Hub and check that it can communicate with the device:
Here we can see that our edgeAgent module is running!
