How do I set up the Commission Flow?

Please refer to the link below. How can I configure the Commission Flow according to the requirements?

Hi,

Please take a look at the fllowng:

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/matter/overview/commissioning.html 

Hope this helps.

Hi

What I mean is the configuration, which could be factory data or the prj.conf settings.

As shown in the image below

0:Standard, 1:User-Intent, 2:Custom.

Hi,

I am checking this internally and will get back to you soon.

Hi,

What I understood from your query is, how to change the Commissioning Flow bits in the BLE advertisement using either prj.conf or Factory Data configuration? ope this is correct.

The Commissioning Flow is not defined by the FW but by QR code and DCL entry. The Custom Flow bits are only part of QR code. When manual pairing code is used, then Custom Flow bits are not present there, but instead Matter Controller can look at VID and PID of the device, and then check if Custom Commissioning Flow is necessary by checking the DCL entry of the given device.

 Based on above, there is no KConfig or Factory Data entry for Custom Flow bits.

 There is one place in the code where this Custom Flow can be modified in the code, and this is only for debugging purpose to change printed QR code in the console: 

https://github.com/nrfconnect/sdk-nrf/blob/1d7f28e82f31e751dda42ce40e5b6d1d94fef1aa/samples/matter/common/src/app/matter_init.cpp#L345 

Here you may change it - but it does not have any impact on the device behaviour - it's just helper string in debug logs.

Hi,

Please refer to page 56 of the document. The content described there seems to align with my understanding , when generating the QR code, the 'Commission Flow' should also be configured at the same time. This way, users will know whether any additional actions are required when they scan the QR code.

Yes in the link that you attached, it looks like there is an added field "commissioning-flow" but we don't see any usage of it in the code - which again is understandable, as FW should not have such information.

But anyway, this is correct the commissioning flow should be configured when generating QR code - which is not bound to the FW build process.
