You are welcome and I am happy that I could help!

No it isn't very intuitive. It took me also some time to figure this out 😉

Thank you very much!

I must say that the issue was simple but not very intuitive!

I ran into the same issue after testing BLE-Mesh.

In the app you are only able to select one group at once.

If you want to add another group to the existing, you have to click on "Subscribe" again and then add the wished group.

It should look like this:

Furthermore do a pristine build, after you add the following setting: CONFIG_BT_MESH_MODEL_GROUP_COUNT =3

If you don't already know this video here https://youtu.be/Jt2ui22fBjM?si=gpM0BV5mOqJGGdrY I can highly recommend to watch it.

The app on the phone is nRF Mesh v3.3.2

Thanks.

Which version of the SDK, which device etc. is this? Are you working on a custom board or a DK?

Hi,

in nRF MESH app on my phone:

1) I select the node

2) Then select the model of the element that I want to subscribe

3) Then select "Subscribe"

4) Then select an existing group: here there is a menu with a list of all my groups, but I can select ONLY one group and not multiple groups

I don't know how better explain these operations

I don't see why this shouldn't work.

Can you please give a more detailed description of your setup and steps to reproduce this.

I was not able to reproduce. Although I haven't tested using android.

I have set CONFIG_BT_MESH_MODEL_GROUP_COUNT =3 in prj.conf. (I have three groups in my application)

Then I have rebuilt the project, but when I use tha app I can subscribe only to a single group, as before.

Is there some other variable that I have to set?

The app shouldn't deny you subscribing to multiple groups, but the Mesh node might only support subscribing to one.

Could you check what the CONFIG_BT_MESH_MODEL_GROUP_COUNT is set to in your application?

Hi,

I am using the phone (nRF Mesh app) to configure a mesh node to subscribe to multiple groups.

As I said, I have nRF Mesh app (vers. 3.3.2) installed on my android phone, but it seems that this app permits to subscribe only to a single group.

Hi.

You should be able to subscribe to multiple groups.

Are you using the phone to configure a mesh node to subscribe to multiple groups? Or do you want the phone to subscribe to multiple groups?
