SI-M1 Face SDK License Request

This public DLL-only package requires a project-specific license file for real serial-port runtime usage. Mock mode does not require a license.

License File Path

Place the license file at:

Assets/StreamingAssets/si-m1_face.dat

The SDK reads this file through Application.streamingAssetsPath.

Required Unity Binding Parameters

Provide these values from the Unity project that will run the SDK:

Field	Unity Source
`identifier`	`Application.identifier`
`companyName`	`Application.companyName`
`productName`	`Application.productName`
`version`	`Application.version`
`unityVersion`	`Application.unityVersion`

If any of these values changes, the existing license becomes invalid and a new license is required.

Parameter Probe

Add this temporary script to the customer project and copy the Console output when requesting a license:

using UnityEngine;

public sealed class FaceLicenseParameterPrinter : MonoBehaviour
{
    private void Awake()
    {
        Debug.Log("identifier=" + Application.identifier);
        Debug.Log("companyName=" + Application.companyName);
        Debug.Log("productName=" + Application.productName);
        Debug.Log("version=" + Application.version);
        Debug.Log("unityVersion=" + Application.unityVersion);
    }
}

Request Information

Provide:

Item	Example
Customer name	`customer-a`
Project name	`Face App`
Unity binding parameters	See above
License start time	`2026-08-10T00:00:00+08:00`
License expiry time	`2027-08-10T00:00:00+08:00`
Licensed features	`SerialRuntime,Basic,Verify,Enroll`

License times use Beijing time and must use yyyy-MM-ddTHH:mm:ss+08:00.

Common Failures

Symptom	Cause
License file missing	`si-m1_face.dat` is not under `Assets/StreamingAssets`
Binding mismatch	One of the Unity binding parameters changed
Expired	Current Beijing time is after `expireAt`
Not yet valid	Current Beijing time is before `issuedAt`
Feature denied	The license does not include the requested SDK feature
Invalid signature	The file was modified or does not match this SDK build
