# Set parameters
IOTHUB_NAME=$(terraform output -state=.azure/iot-stream-analytics/infra/terraform.tfstate -raw iothub_name)
STREAM_ANALYTICS_JOB_NAME=$(terraform output -state=.azure/iot-stream-analytics/infra/terraform.tfstate -raw stream_analytics_job_name)
DEVICE_NAME="myDevice"

# Create a device identity
az iot hub device-identity create \
    --hub-name $IOTHUB_NAME \
    --device-id $DEVICE_NAME

# Get the device connection string
CONNECTION_STRING=$(az iot hub device-identity connection-string show \
    --hub-name $IOTHUB_NAME \
    --device-id $DEVICE_NAME \
    --query "connectionString" \
    --output tsv)

# Start stream analytics job
az stream-analytics job start \
    --job-name $STREAM_ANALYTICS_JOB_NAME \
    --resource-group rg-iot-stream-analytics

To send mock data run the following procedures in your local environment.

1. Open Raspberry Pi Azure IoT Online Simulator
2. Override connectionString to $CONNECTION_STRING of your device connection string
