Bluetooth Mesh: Mesh Proxy not relaying data properly?

[CSparn]

Hi,
I'm trying to setup a mesh network with one proxy node and at least one relay node. As provisioner I'm using NRf mesh app for Android. All nodes are running in Qemu on RaspberryPis using a modified version of mesh shell app from tests folder.

What I'm doing:

1. Start the proxy node (mesh init)
2. Start advertising (pb-gatt)
3. Provision the proxy with NRf app (working well)
4. Start the relay node (mesh init)
5. Start advertising (pb-gatt or pb-adv)
6. Try tp provision the relay node with NRf app (working partially)

Now there is coming up a problem. Like I understood it it possible to provision the relay not either directly over the NRf app using pb-gatt (working without getting the composition data) or to provision the relay node relayed over the proxy with gatt and pb-adv? But when trying to use pb-adv over gatt proxy no unprovisioned device is shown in NRf mesh app. Is it possible that this is not workoing with the app?

If I'm using the direct provisioning over pb-gatt, I see the node in the NRf app, but I can not configure it, even if I am connected to the gatt proxy. So the question is why this is not working? Is there missing any code that I have to run on proxy side to relay the information to the NRf app? Or are there any options missing in the config file that I forgot?

My config file looks like this:
prj.zip

If anyone knows why this is not working or has an idea for a working test set I'm very thankful.

Hi,

I could find a solution for this by chance. The following things are important:

1. The Mesh Proxy feature and relaying data with it ist not working with internal bluetooth adapter of the RaspberryPi! But when using a bluetooth dongle and connect it to the Pi it is working. (I will open a bug report for that.)
2. The config CONFIG_BT_MESH_GATT_PROXY has to be set to y.
3. The config CONFIG_BT_MESH_GATT_PROXY_ENABLED can be set to y. If not the proxy feature has to be enabled over the NRf app before data can be relayed over the proxy.
