Raspberry pi iot edge on raspian

1. Start Raspberry Pi Imager

   • select Raspberry Pi Os Lite 32-bit
   • configure hostname
   • enable ssh
   • set password
   • configure wireless lan
   • set timezone Write to SD and put in pi wen finished. I used rpi4iotedge.local as a hostname

2. ssh [email protected] -sudo raspi-config

   • advance options -> expand file system
   • interface options -> enable SPI and GPIO
   • update

3. portal.azure.com

   • Create IOT Hub (rpi4iothub)
   • Create Iot Edge Device (rpi4device)

4. Install IOT Edge https://docs.microsoft.com/en-us/azure/iot-edge/how-to-provision-single-device-linux-symmetric?view=iotedge-2020-11&tabs=visual-studio-code%2Crpios on Raspberry Pi OS

curl https://packages.microsoft.com/config/debian/stretch/multiarch/prod.list > ./microsoft-prod.list sudo cp ./microsoft-prod.list /etc/apt/sources.list.d/

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg sudo cp ./microsoft.gpg /etc/apt/trusted.gpg.d/

5. Install Container engine from same do on Raspberry Pi OS

sudo apt-get update;
sudo apt-get install moby-engine

6. Install IoT Edge runtime from doc above

sudo apt-get update;
sudo apt-get install aziot-edge

7. Created default modules on iot edge device

   • $edgeAgent
   • $edgeHub

8. provision device with cloud identity in doc above using "Primary Connection String" from IoT Edge device

sudo iotedge config mp --connection-string 'PASTE_DEVICE_CONNECTION_STRING_HERE'

sudo iotedge config apply -c '/etc/aziot/config.toml'

- Test your connectivity between cloud and rpi with
    sudo iotedge check

1. arm32v7 Remote development requires docker group to run on pi without sudo ssh to pi and: groupadd docker usermod -aG docker $USER newgrp docker -test setting like this docker run hello-world

   • https://devblogs.microsoft.com/iotdev/easily-build-and-debug-iot-edge-modules-on-your-remote-device-with-azure-iot-edge-for-vs-code-1-9-0/ https://www.digitalocean.com/community/tutorials/how-to-set-up-ssh-keys-on-ubuntu-20-04

2. in vs code user settings from command line pallet add these lines only ip of rpi works for some reason do not try name "azure-iot-edge.executor.env": { "DOCKER_HOST": "ssh://[email protected]" },

3. during sample build getting internet connectivity errors and not able to restore packages on rpi:

• sudo iotedge check was also throwing container connectivity errors doc: https://docs.microsoft.com/en-us/azure/iot-edge/troubleshoot-common-errors?view=iotedge-2020-11 sudo nano /etc/sysctl.conf
  • uncomment line below net.ipv4.ip_forward=1 sudo systemctl restart docker If there are errors with pulling local image from local repository in devcontainer.json uncomment: "forwardPorts": [5000, 5001],

4. Nuget restore throws errors so trying this dns setting to see if it helps (IT WORKS!)

   • https://docs.microsoft.com/en-us/azure/iot-edge/troubleshoot-common-errors?view=iotedge-2020-11#edge-agent-module-reports-empty-config-file-and-no-modules-start-on-the-device { "dns": ["1.1.1.1"] }

   • in /etc/docker/daemon.json file

   • Then: sudo systemctl restart docker

5. running powershell from c# https://docs.microsoft.com/en-us/powershell/scripting/developer/hosting/windows-powershell-host-quickstart?view=powershell-7.2
