Distributing a Skill to a Product (Manufacturers)
This section describes how manufacturers of camera devices running HiSilicon Hi35xx series chips manage products, purchase skills, and bind device licenses to product skills on the Huawei HiLens console to enable the devices with AI capabilities.
This chapter describes how to purchase a skill oriented to HiSilicon Hi35xx series chips to demonstrate the entire process from product creation to skill use. Free test skills are available in the skill market for trial use, but we do not guarantee their commercial precision.
Before you start, carefully complete the preparations described in Preparations.
Preparations
Register a HUAWEI CLOUD account. Before using Huawei HiLens, check the account status, which cannot be in arrears or frozen.
Step 1: Create a Product
- Log in to the Huawei HiLens console. In the left navigation pane, choose Device Management > Products. The Products page is displayed.
- Click Create Product in the upper right corner and set product parameters, as shown in Table 1.
Figure 1 Creating a product
Table 1 Product parameters Parameter

- Select the new product and click Download License in the Operation column to download the license file.
The license contains the identity information of the product, which is used for registration verification with the skill SDK.
Step 2: Purchase a Skill
You can purchase required skills from the skill market of Huawei HiLens based on your service requirements to develop devices running HiSilicon Hi35xx series chips. The skills can be used for Hi3516EV200, Hi3516CV500, Hi3519AV100, Hi3519V101, Hi3516DV300, and Arm chips..
This example describes how to purchase the free Human_Face_Detection_Offline_3516EV200_HiLinux skill, which is used to develop devices running HiSilicon Hi35xx series chips.
- Log in to the Huawei HiLens console. In the navigation pane on the left, choose Subscribe > All Skills. The Skill Market page is displayed.
- Search for Human_Face_Detection_Offline_3516EV200_HiLinux in the skill search box and click the skill card. The skill details page is displayed.
- Click Buy Now. The page for purchasing skills is displayed.
- Specify Copies. You can retain its default value. The Specifications is default to Channel(s), indicating that a license can be installed on one device to use one channel of video.
Figure 2 Purchasing the skill
- Confirm the price and click Buy Now.
After the purchase is successful, you can click Purchased to go to the Subscribe > Order Management page and distribute the skill.
Figure 3 Successful purchase
- Go to Subscribe > Order Management to distribute the skill.
Step 3: Use the Skill
Skills oriented to HiSilicon Hi35xx series chips can be used only after being distributed to device groups. For devices that run HiSilicon Hi35xx series chips, a maximum of five skills can be distributed to a device group due to performance restrictions.
- Log in to the Huawei HiLens console. In the navigation tree on the left, choose Subscribe > Order Management. The Skill Orders tab is displayed by default.
- Select a skill designed to run on HiSilicon Hi35xx series chips, and distribute the skill license to a product group.
- Select the skill to be distributed and click Distribute in the Operation column.
- In the Distribute to Product dialog box, select the product group to which the license is to be distributed, and click the Distribute to Product button.
If you select Yes under Automatic Upgrade, the skill in the product will be automatically upgraded to the latest version if a new skill version is available. This function is not available yet and will be provided.
Figure 4 Distributing a skill
- The skill distribution information is displayed in the dialog box. Confirm that the Installation Status is Successful and click OK.
- On the Skill Orders tab page, select the skill you want to use and click Download in the Operation column. The browser automatically downloads the SDK package of the skill.
Figure 5 Downloading SDK
- Install the skill. Integrate the downloaded SDK package to the device.
The device location where the skill is integrated varies according to the device. For details, see the description document in the SDK.
