Cannot bind app key for one of the model with PYACI Script

[SaSu]

Hello

I am trying to bind app key for one of the models with the help of PYACI Python script. I am using latest version v5.0.0 for PYACI script and downloaded it here: https://github.com/NordicSemiconductor/nRF5-SDK-for-Mesh , also with same version of documentation for commands https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v2.1.1%2Fmd_scripts_interactive_pyaci_README.html.  And I am using Raspberry pi where my py script is running and nRF52840 with Serial Script running connected to Raspberry Pi with Ports /dev/ttyACM0 (or) /dev/ttyACM1. I am trying to bind app key for Sensor_Server Example and i get like this where all the earlier commands works well.

NOTE: examples are connected to Laptop which is obvious where we can run with bluetooth

 I also tried with Mesh Chat sample like above and get same problem

Another Question: we can identify the sample with last model ID where vendor Setup Model ID bound to "0059000a" which is 8 bit and where it should be 4 bit. Even in app i get the same ID

which is ok to setup in app but in this command - cc.model_app_bind(db.nodes[0].unicast_address, 0, mt.ModelId(0x1000)) it should have only 4 bit right?

Please help me as soon as possible. I really in need of help to continue my work further

Regards

In your earlier report, I understand that the second device needs index == 0, but what about the first one? Does it also work with index == 0?

Yes first one also works with index==0 but i could not complete the provisioning process as i have problem in publication step, command number: 26.

I still cannot reproduce the problem where the second node provisioned need to use index 0 to work.

I am wondering if you are using the correct parameters with publish_set() part...

Could you please post the full log of your attempt, in text form. In addition to the normal steps, each time before you call model_app_bind(), please also you run the following:

len(db.nodes)
db.nodes[0]
db.nodes[1]

Remember to redact the device key from the output of db.nodes[x].

I checked the printing scanned device address topic. This is currently not possible, because the serial firmware on the interface device does not send this information back to the script. See: Serial Event Details > Prov Unprovisioned Received.

If this is very important, I think you can look into the Serial example and see if you can update both the device firmware and the PyACI script to send, receive, and parse the advertising name in the Unprovisioned Received event.

The publication step is a part of the configuration, not the provisioning. I suspect this might have the same root cause as the index mix up.

Can you help me with the model id how to use 8 digit to 4 digit id:

yes i also have the same idea

Look at the ModelId class __init__ method, you can see that it accepts both the model_id and the company_id.

The company_id is relevant and should not be left default for the case of Vendor Models, and the Chat Model is one. Thus, instead of calling mt.ModelId() with the full four-byte ID, please call it with the two-byte Model ID and then the two-byte Company ID.

still says invalid model
