nrf52840 vendor model unable to subscribe to groups in nrf mesh app

[anuprit]

Hi,

I have changed the vendor model for sending data from client to server in light switch example. Earlier it was just sending bool values. I have changed it to uint8_t to send data.

But now i am unable to subscribe the server dongle to any group in nrf mesh app, it gives an error "not a subscription model".

I am able to provision both the dongles. Client(switch) has been set to a publish address through the app.

App is not supporting vendor models?

If not then can i give a subscription address in my code to the server(light) node directly? I will provision the nodes via app but address will be taken from the code.

Thanks

Hi,

The application should be able to configure any model, as all configuration is done using configuration models. The error "not a subscription model" make me think there is something else wrong with the model. What exact changes have you done to the example, can you share the changes?

If you still use the assigned number for Generic OnOff, but has changed the model to use a different type of data or different messages, then that would mean the nRF Mesh app is probably not able to send the correct messages. But that would be an error that appears when you try to send messages to the model, it should not appear as early as configuration.

Just for the records: A vendor model must call access_model_subscription_list_alloc() for subscriptions to work. Omitting it will cause subscription related messages to fail with error code 8 - NOT_A_SUBSCRIBE_MODEL. For details see:

Hi,

Thank you for chiming in on this one. This might very well be the issue from the opening post, and in any case something others should watch out for when creating their own models.
