Change the "setup pin code" for test project? (CON-1580)

[dzungpv]

I want to test same matter in the same network, but the problem all setup code is the same for test devices. I want it simple to test so not using chip-tool or mfg-tool to generate partition.

It is:

• Discriminator: 3840
• Setup-pin-code: 20202021

But there is no config to change that. Seem in examples there is no option to change that.
And the code set by the parent chip code in: CHIP_DEVICE_CONFIG_USE_TEST_SETUP_PIN_CODE https://github.com/lucicop/connectedhomeip/blob/df2c8e9072714273caad5c60ed9ce1b4911cf662/config/standalone/CHIPProjectConfig.h#L42

I see that it include in the

esp-matter/examples/controller/sdkconfig.defaults

Line 12 in a960281

CONFIG_USE_TEST_SETUP_PIN_CODE=20212020

but seem not using anywhere.

You can change the discriminator here: https://github.com/project-chip/connectedhomeip/blob/13da787aeb078fb79587139aef0f266e9d2b7c63/src/include/platform/CHIPDeviceConfig.h#L1233, but for the setup pin code, you shall not change it with the spake2p unchanged.

I have try that but when discriminator change from 3840 to 3850 code setup code gen using https://github.com/espressif/connectedhomeip/tree/9b8fffe0bb4e7ba7aac319f5905070a3476db7cb/src/setup_payload/python output the same:

So I know by reading the code, when changing setup pin code the spake2p must be change. I see in the #760 seem the proper way to change that with code.

But the is simple way to change CHIP_DEVICE_CONFIG_USE_TEST_SETUP_PIN_CODE and re calculate https://github.com/project-chip/connectedhomeip/blob/13da787aeb078fb79587139aef0f266e9d2b7c63/src/include/platform/CHIPDeviceConfig.h#L1282. I try change it but not working, may cause by build cache. You may add if in menu config and gen code for that, it is simpler to change the code when testing, rather simple than using mfg-tool to built the partition like in production.

@Jerry-ESP I try the example light_switch project and enable:
CONFIG_CUSTOM_COMMISSIONABLE_DATA_PROVIDER=y
CONFIG_DYNAMIC_PASSCODE_COMMISSIONABLE_DATA_PROVIDER=y
To generate random setup code each time, but it is not working. Seem this example outdated.
I plan to use this and use 8 char off MAC address , but original code not working. Log:

Yes, it work now. I can pair using the code and chiptool.
How to generate qr install code the fly? I mean generate QR install code from the generate setup code and show the the log console like esp-rainmaker or to show on a LCD scsreen

How to generate qr install code the fly?

You can get the QR code by typing the command in device console matter onboardingcodes ble qrcode. This will generate the QR code for BLE pairing.

BTW, the dynamic passcode commissionable data provider could only be used when a device have a display which can show the QR code or you can get the QRCode/ManualCode with other methods(For example, you can make the device connected to the cloud with other provisioning approach and get the QR code from the cloud). For normal usage to use unique Setup-PIN&Discriminator, please refer to https://docs.espressif.com/projects/esp-matter/en/latest/esp32/production.html
