esp_matter_controller pairing queries (CON-1420)

[pavel808]

I am using the new pairing_code_thread() API which works well. I have two questions :

1. How do I assign a callback to get the commissioning status (success or fail) when calling that particular pairing_code_thread() function? I see that there is a pairing_command class which can be used to assign callbacks when an object is created, but doesn't yet have parameters for working with pairing codes or QR codes.

My guess is that this is still under development?

2. Is there a n API implemented for unpairing / de-commissioning a device yet?

Thank you in advance.

Hi, there are some callbacks in the pairing_command class to notify whether the pairing and commissioning are successful/failed. When the PASE session is established or when there is an error during PASE session establishment the OnPairingComplete will be called. When the commissioning is completed, OnCommissioningComplete will be called. but currently there are still some callbacks not implemented and we still need some APIs for the users to set their custom callbacks. We will add them later

For the second question, you can use controller_instance.get_commissioner()->UnpairDevice(peerNodeId) to unpair a device. The commissioner will remove the fabric of the remote device in that function.

@wqx6 Thanks again. Currently I am not creating a pairing_command object and just calling the pairing_code_thread() function which is not part of the pairing_command class.

I guess the pairing_command class has yet to be updated to have a pairing code / QR code field ?

Alternatively, can I still create a pairing_command object anyways, but call the pairing_code_thread() function separately and still have the callbacks updated as expected?
