Invalid Model when trying to bind app key to Level model

[Andre Lochner]

Hi

When I select the Generic Level server model and try to bind the app key I get an invalid model Error. I am using the nRF Mesh android app.

This might be relevant or no but i see this in the debug terminal when provisioning

config_server.c,  629, dsm_appkey_add(appkey_handle:0 appkey_index:0)

I have two elements 0x0002 has 3 models

Configuration server

Health server

Generic on Off server

element  0x0003 has my model Generic Level server

My settings is as follow :

ACCESS_MODEL_COUNT (6)

ACCESS_ELEMENT_COUNT (3)

Thanks for any help !

Hi,

What Mesh SDK version are you using? And which example? Is ACCESS_MODEL_COUNT and ACCESS_ELEMENT_COUNT the only modifications you have done?

[Andre Lochner]

Hi,

I am using version v3.2.0. I used the light switch server as my starting template and I have added a level model to it. I did the same with the client and it is working fine and can subscribe to level model. I have made a mod to ACCESS_SUBSCRIPTION_LIST_COUNT is a well. I have played around with various values and at the moment I have it as follow ACCESS_MODEL_COUNT (6), ACCESS_ELEMENT_COUNT (4), ACCESS_SUBSCRIPTION_LIST_COUNT (ACCESS_MODEL_COUNT+2)

Andre Lochner said:

So it works fine when trying to bind the app key to the Generic Level client model?

[Andre Lochner]

Yes, works fine with the client model. Its only with the server model where I get this error when I assign an app key.
