The download URL in this case is:
The downloaded QR code is packaged in a zip file, as shown below.
After decompressing QR code zip file, you can use the Gizwits Debugging App to directly scan the QR code and bind the device.
In the App development, you need to call the device binding API through QR code in the Gizwits App SDK. QR code scanning can be implemented through a third-party framework (such as zxing). You can refer to the Gizwits App Framework code. The specific API call for device binding in Gizwits App SDK is as follows, taking Android as an example:
