Generated QR-code does not contain VendorId, ProductId?

[olavt]

I'm not sure if this is causing any practical issues / problems, but I notice that the generated QR-code from using the "open_commissioning_window" command to the Python Matter Server is a bit different from the QR-code generated by the equivalent chip-tool command. I find it a bit strange, since it looks like the parameters sendt to the SDK looks identical.

When I send the "open_commissioning_window" specifying just the node_id as an argument, I get a QR-code like this:

MT:00000CQM007KJZ6LN10

If I parse it using the chip-tool command:

./chip-tool payload parse-setup-payload MT:00000CQM007KJZ6LN10, I get:

Here both VendorID and ProductID are zero.

Using the chip-tool command to open a commissioning window like this:

./chip-tool pairing open-commissioning-window 1 1 600 1000 3840

results in a QR-code like this:

MT:6FCJ1AFN00ETFH1TR10

If I parse it using the chip-tool command:

./chip-tool payload parse-setup-payload MT:00000CQM007KJZ6LN10, I get:

[1741032369.114] [12551:12551] [SPL] Passcode: 81893170

Here the values for VendorID and ProductID are correct.

Why the difference?
