How can I execute a command to commission a device for Thread by using the QR code or pairing code?

How can I execute a command to commission a device for Thread by using the QR code or pairing code? (without using the pin_code or discriminator) Thanks.

From following instructions on how to use chip-tool to commission Matter devices to work over Thread, I see the following command: chip-tool pairing ble-thread node_id hex:operational_dataset pin_code discriminator However, what if I want to use the device QR code or pairing code for commissioning for Thread?

Hi, 

See the Commissioning with QR code payload or manual pairing code section.

Thanks, 

so in this case, we don't need to specify ble-wifi or ble-thread in the chip tool command if commissioning using the QR code or pairing code? Just

chip-tool pairing code <node_id> MT:#######

So no networking credentials or dataset is required to connect to the network? I find this very confusing now.

It is used when the Matter device is already present in an IP network, but it has not been commissioned to a Matter network yet. To commission the device, you can use either the setup PIN code or the setup PIN code and the discriminator, both of which you obtained in the step 5. Alternatively, you can also use a QR code payload. See the steps in the Using CHIP Tool for Matter device testing.

I can already add a device to the matter network using the pin code and discriminator. I have read the link you provided, and I also implement it according to the steps of this link.  But I want to use chip tool to add devices from other manufacturers in the market. These devices only provide QR code, instead of pincode and discriminator. So we want to know how to add these matter over thread devices to the market through the chip tool command. Do you have any ideas ?

Are those Matter devices already present in an IP network? If so, you can commission them with QR code payload or manual pairing code.

This is a matter over thread device, the OTBR is built on the Raspberry PI environment, and the chip tool runs on the Raspberry PI. How to make this purchased matter over thread join the ip network, or what commands should I use to make this device join the ip network ?
