NRF Connect SDK of Matter Alexa commissioning problem

[mg Jeong]

Hello,
I modified and tested the Mater sample of ncs v2.3.0. (bulb sample)

I'm currently connecting home hubs from various manufacturers to Mater, and I'm having issues with the harmful Amazon Alexa commissioning.
It seems that one operation does not become kCommissioningComplete until PairingAttach.
In addition to the Nordic board, the ESP32 board makes Alexa commissioning no problem.

The board used is the nrf7002DK board and works with Matter via WiFI.
Below is the corresponding log.
please confirm. thank you.

Hi,

I modified and tested the Mater sample of ncs v2.3.0. (bulb sample)

Which modifications did you do? Are you able to commission a pristine Matter Light Bulb sample from NCS v2.3.0?

Kind regards,
Andreas

There is a problem that multi-admin does not work after commissioning by uploading CHIPTOOL on Raspberry Pi.

The part I modified was in the commissioning process.
To determine which manufacturer has been commissioned
From source Advertiser_ImplMinimalMdns.cpp
CHIP_ERROR AdvertiserMinMdns::Advertise(const OperationalAdvertisingParameters & params)
I made a modification to get the instanceName as a global variable in the function. Please inquire if commissioning is not possible because of the modification.

if (!operationalAllocator->AddResponder<PtrResponder>(compressedFabricIdSubtype, instanceName)
             .SetReportAdditional(instanceName)
             .SetReportInServiceListing(true)
             .IsValid())
    {
        ChipLogError(Discovery, "Failed to add device type PTR record mDNS responder");
        return CHIP_ERROR_NO_MEMORY;
    }

    AdvertiseRecords(BroadcastAdvertiseType::kStarted);
        
    ChipLogProgress(Discovery, "mDNS service published: %s.%s", StringOrNullMarker(instanceName.names[1]),
                    StringOrNullMarker(instanceName.names[2]));

    //Set_Ble_Status(&gBle_Status, COMM_NET_CONNECTING);                               //====== DELETED later FOR POC ======

    if(strstr(instanceName.names[0],"4188")) // 20021348 account ALEXA
    {
        instanceNameAlexa = instanceName.names[0];
        instance2Byte = 1;
    }
    else if(strstr(instanceName.names[0],"2D8B")) //iotdevpoc account ALEXA
    {
        instanceNameAlexa = instanceName.names[0];
        instance2Byte = 1;
    }
    else if(strstr(instanceName.names[0],"C335")) //APPLE
    {
        instanceNameApple = instanceName.names[0];
        instance2Byte = 1;
    }
    else if(strstr(instanceName.names[0],"909F"))// APPLE
    {
        instanceNameApple = instanceName.names[0];
        instance2Byte = 1;
    }
    
    else if(strstr(instanceName.names[0],"382B")) // 20021348 account SAMSUNG 
    {
        instanceNameSamsung = instanceName.names[0];
    }
    else if(strstr(instanceName.names[0],"F2A3")) // CHIP
    {
        instanceNameGoogle = instanceName.names[0];
    }
    //948F
    
    // else if(strstr(instanceName.names[0],"909F"))
    // {
    //     instance2Byte = -1;
    // }
    return CHIP_NO_ERROR;
}

I've queried the Matter team and will get back to you with an answer to your question as soon as I hear from them

Kind regards,
Andreas

[mg Jeong]

Thank you, please reply as soon as it is confirmed

[AHaug]

Hi, 

I see that this case has fallen in between two chairs (so to speak). Apologies for the inconvenience that has caused. Could you verify if this inquiry is still something that you need an answer to or if you've resolved it yourself in the meanwhile? I'll push for a response from the Matter team if you still need an answer

Kind regards,
Andreas

Hi,

I haven't been able to resolve that issue yet.
If you think it is necessary for material analysis, we would appreciate it if you could leave an inquiry to the Matter team.

Hi,

Some feedback here from the Matter team. Following the information they were able to extract from this case they were not able to reproduce the commissioning issues you're observing with NCS v2.4.1, which is the first SDK version with WIFI production support, i.e the version of the SDK which is now recommended for WiFi. Are you able to to get everything up and running with NCS v2.4.1 instead of 2.3.0?

Regarding the part of the case they might need more information from: It is hard to understand what specifically does not work, so if you can provide a step-by-step reproduction guide that might be helpful. 

Could you also explain what the code modification achieves? I.e did it resolve the issue?

Kind regards,
Andreas
