NRF MESH provisioner node - appKey error

[loulou1844]

Hi,

I am in the process of provisioning and configuring a 2-element light switch server node and a common light switch server. I am using the orginal exemple for the provisioner and common light switch server and a modified 2-element light switch server node.

When I start the configuration with the 2-element node it works but the following configuration freezes while searching for the appKey. (Terminal_provisioner_view)

In the reverse order everything works normally.

I have attached debug terminal from each point of view.

Thanks.

(using nrf52840-DK / Mesh v4.1.0 / SDK v16.0.0)

Hi Loulou, 

Could you debug and check what's the value of the return code when config_client_appkey_add() called in the provisioner ? 

What's the output of the log on the client ? has it receive the app_key adding packet ?

The node_setup.c is designed with some specific scenario so it might not work out of the box when you add more element into the server. The node_setup.c might need to be modified, I'm not sure.
If you configure 2 servers each with 2 elements would it work ? 

[loulou1844]

Hi,

This function returns 0 in any case. (bug and not)

No problem with the client, its configuration is a success every time.

I can understand that senario are quite rigid but an unconfigured element should not cause probleme.

Hung Bui said:

If you configure 2 servers each with 2 elements would it work ? 

It depends, sometimes yes, sometimes no. It's very difficult to study this kind of random bug. That's why I found a case where it crashes every time: configuring a node with 2 elements and then a node with 1 element.

Thanks

[Hung Bui]

Could you provide us the server code so we can reproduce the issue here ? 

[loulou1844]

Thank you for your quick responses.

I had time to retry your question : "If you configure 2 servers each with 2 elements would it work ?" I have attached the full terminal with one succes and one failure. I tried around 10 times and it had succed 3, it seems random.

I hope you can reproduce the issue.

(using 3 x nrf52840-DK / Mesh v4.1.0 / SDK v16.0.0)

Hi LouLou, 

I tried your code here but I didn't see the crash. I assume you saw the provisioner crashed ?
However, I had a look at the provisioner and it seems that the provisioner was not designed to provision the 2nd element of the server. 

If you look at the config_scenarios.h you can find how it's defined. For example the light switch client will be configured as follow: 

#define CONFIG_SCENARIO_LIGHT_SWITCH_CLIENT_EXAMPLE    \
    CONFIG_SCENARIO_COMMON,                            \
    CONFIG_ONOFF_CLIENT,                               \
    CONFIG_ONOFF_CLIENT,                               \
    NODE_SETUP_DONE

You can find that there are 2 CONFIG_ONOFF_CLIENT being configured. And on top of each CONFIG_ONOFF_CLIENT  there is a NODE_SETUP_GET_NEXT_ELEMENT . The reason for this is that the config_onoff_client is not located on the first element but located on the 2nd and 3rd element. 

It's a little bit different in your 2 elements server case. Your first server model is located on the 1st element with other model for example the Health model. 

So what I did to modify the configuration scenario is to add CONFIG_ONOFF_SERVER2 as follow: 

#define CONFIG_SCENARIO_LIGHT_SWITCH_SERVER_EXAMPLE    \
    CONFIG_SCENARIO_COMMON,                            \
    CONFIG_ONOFF_SERVER,                               \
    CONFIG_ONOFF_SERVER2,                               \
    NODE_SETUP_DONE

#define CONFIG_ONOFF_SERVER2                      \
    NODE_SETUP_GET_NEXT_ELEMENT,                 \
    NODE_SETUP_CONFIG_APPKEY_BIND_ONOFF_SERVER,  \
    NODE_SETUP_CONFIG_PUBLICATION_ONOFF_SERVER,  \
    NODE_SETUP_CONFIG_SUBSCRIPTION_ONOFF_SERVER

Attached is the config_scenatios.h I used. Note that I haven't modified the subscription address for the 2nd server, so it subscribe to the same group as the 1st server.

Hi,

Yes, on my side it crashes during the second configuration.

I did something similare with the senario file but it seems like the previous random bug.

#define CONFIG_SCENARIO_LIGHT_SWITCH_SERVER_EXAMPLE    \
    CONFIG_SCENARIO_COMMON,                            \
    CONFIG_ONOFF_SERVER,                               \
    NODE_SETUP_GET_NEXT_ELEMENT,                         \
    CONFIG_ONOFF_SERVER,                               \
    NODE_SETUP_DONE

If you say that you can't see the crash, I will try to reset my setup.

[Hung Bui]

Yes, please debug deeper and find why it crashes/stop continuing. Testing on a fresh copy of the SDK could be a good idea.
