Learn Azure Sphere together (5)-Provision Azure Sphere to Azure China

note:

This article actually introduces a case of connecting multi-tenant IoT Hub through DPS:

Provision devices to Azure China IoT Hub through Azure Global DPS- Link Azure IoT Hub on Azure China to Device provisioning Service on Azure Global

The content of this section is as follows: How to talk about Azure Sphere provisioning to Azure IoT Hub in China

1. Create DPS in Azure global;

2. Create IoT Hub in Azure China;

3. Connect Azure China IoT Hub to Azure Global DPS through Azure CLI;

4. Register Azure Sphere to Azure China IoT Hub through Azure Global DPS;

Graphic introduction:

Actual combat steps:

1. Create DPS in Azure global;

2. Create IoT Hub in Azure China;

3. Connect Azure China IoT Hub to Azure Global DPS through Azure CLI;

4. Register Azure Sphere to Azure China IoT Hub through Azure Global DPS;

This article only demonstrates step 3. The rest of the content has been introduced in other articles and will not be repeated.

In many scenarios, we need to configure the DPS to connect to the multi-tenant IoT Hub:

such as:

1. The device manufacturer provides a DPS, but the actual Azure IoT Hub is provided and saved by the customer;

2. Register a certain type of device with regional characteristics to the specified Azure IoT Hub, for example, register a Chinese voice sweeping robot to the Azure IoT Hub in China, and the English version to the Azure region in the western United States;

3. Register a specific product to a specific Azure region according to the user's place. For example, in this example, if a device that uses Azure Sphere is only available in China, you need to register Azure Sphere to Azure China.

For the multi-tenant configuration of DPS, see the official website document: https://docs.microsoft.com/zh-cn/azure/iot-dps/how-to-provision-multitenant

For normal single-tenant configuration, the Azure IoT Hub can be selected through the drop-down list in the Azure Portal, see the following figure:

In a multi-tenant scenario, you cannot see someone's IoT Hub under your own tenant, and you cannot complete it on Portal.

At this point, you can use the Azure CLI. In this example, we use Cloud shll to complete the command:

For the executed commands, please refer to:

az iot dps linked-hub create --connection -string " target IoT Hub connection string, care to preserve the double quotes" 
                             - DPS-name 
                             --location 
                             --resource-Group 
                             [--allocation-weight] 
                             [--apply- allocation-policy {false, true}] 
                             [--no-wait] 
                             [--subscription]

The required parameters are as follows:

--connection-string

The target IoT Hub, in this case the Azure China IoT Hub connection string, can be found at:

--dps-name

The DPS name of Global Azure in this example

--location

IoT Hub的 location，本例中为中国东部2，chinaeast2

--resource-group

DPS的resource group

在页面下方执行：

本例中，执行如下：

az iot dps linked-hub create 
--connection-string "HostName=xxx.azuredevices.cn;SharedAccessKeyName=iothubowner;SharedAccessKey=xxx" --dps-name dps-global-seanyu 
--location chinaeast2 
--resource-group seanyu_azure_sphere_test

执行完成可以在页面上查看结果：

实际上到此已经结束了。

可以通过文章《使用DPS通过对称密钥进行单个设备注册》进行创建组注册或单个注册并通过模拟设备进行测试，是否能通过Azure Global 的DPS 将设备注册到Azure China中国区IoT Hub。
