Internet of Things(IoT) Hand book

IoT Hand book is a quick reference to all things related to design and development of the IoT solutions specifically on Microsoft eco system (Azure).

In the recent years, organizations have shifted their focus more on IoT adoption and usage. This shift is due to the technology progress and maturity in terms of the hardware sensors, devices and software, improved connectivity over cellular network, production ready hardware and even the ability to run the IoT solutions at the edge.

Today we have tremendous development tooling, cloud and edge computing options to build richer IoT solutions. The handbook provides some solution, tips & tricks, cheat sheets and reference to Microsoft.

Solutions

IoT Hub - Create/Delete & Properties display

IoT Hub - Create

az iot hub create --name <iothubName> -resource-group <resourceGroupName> \
     --sku <skuname>

For tier and pricing information refer to documentation.

IoT Hub - Delete

az iot hub delete --name <iothubName>  -resource-group <resourceGroupName>

IoT Hub - Properties Display

az iot hub show --query properties.eventHubEndpoints.events.endpoint \
     --name <iothubName>

az iot hub show --query properties.eventHubEndpoints.events.path \
     --name <iothubName>

az iot hub policy show --name service --query primaryKey \
     --hub-name <iothubName>

Display the primary connection string

 az iot hub show-connection-string --name <iothubName> \
     --key primary --query connectionString -o tsv

IoT Hub - Retrieving Iot Hub Connection String (Backend Apps)

az iot hub show-connection-string --policy-name service \
     --name <iothubName> --output table

Generate Iot Hub SAS Token

az iot hub generate-sas-token --device-id MyTestDevice --hub-name {YourIoTHubName}

IoT Hub - Device Registration/Connect

IoT Hub - Registering a Device

az iot hub device-identity create \
  --hub-name <iothubName> --device-id <devicename>

IoT Hub - Displaying a Connection String of the Device

az iot hub device-identity show-connection-string \
     --hub-name <iothubName> --device-id <devicename> --output table

IoT Hub - Monitor

az iot hub monitor-events --output table --hub-name <iothubName>

IoT Hub - IP Filter Rules

IoT Hub - Retrieve current IP filters

az resource show -n <iothubName> -g <resourceGroupName> --resource-type Microsoft.Devices/IotHubs

IoT Hub - Add IP filters

az resource update -n <iothubName> -g <resourceGroupName> \
     --resource-type Microsoft.Devices/IotHubs \
     --add properties.ipFilterRules "{\"action\":\"Reject\",\"filterName\":\"MaliciousIP\",\"ipMask\":\"6.6.6.6/6\"}"

IoT Hub - Delete IP filters

az resource update -n <iothubName> -g <resourceGroupName> \
     --resource-type Microsoft.Devices/IotHubs \
      --add properties.ipFilterRules <ipFilterIndexToRemove>

Routing

Create the route for the storage endpoint

az iot hub route create \
  --name $routeName \
  --hub-name $iotHubName \
  --source devicemessages \
  --resource-group $resourceGroup \
  --endpoint-name $endpointName \
  --enabled \
  --condition $condition

DPS

Linking DPS and IoT Hub

az iot dps linked-hub create --dps-name <dpsname> \
     --resource-group <resourceGroupName>  \
     --connection-string <hubConnectionString> --location <location>
