[mesh-cfgclient] 'discover-unprovisioned on' does not detect nodes available on other system

[vincentPlanat]

Hi,

I'm testing mesh using 2 raspberry PI 5 on which I've recompile & install the latest 5.77 version
I try a basic test where on
PI-1 I join (mesh-cfgclient) a node
PI-2 I try to discover it

I can discover the node on PI-1 but not on PI-2 .... ?
Same system on both side, same stack, same version

Find below my test case.
If an expert in the community could help me that would be great !!!

Regards

On both PI
sudo systemctl disable bluetooth
sudo systemctl stop bluetooth
in /etc/bluetooth/main.conf, AutoEnable=false then reboot

On PI-1
Terminal-1
sudo rm -rf ~/.config/meshcfg/config_db.json
sudo rm -fr /root/.config/meshcfg/config_db.json
sudo rm -rf /var/lib/bluetooth/mesh
sudo mkdir /var/lib/bluetooth/mesh
sudo /usr/libexec/bluetooth/bluetooth-meshd -nd --debug

Terminal-2
sudo mesh-cfgclient
create

Terminal-3
pyhton3 test-mesh
join
==> here I get: Joining with UUID 346d6b0cf5b8446d9beff2078ec9bfdf

Terminal-2
discover-unprovisioned on
list-unprovisioned
==> Here I get:
Unprovisioned devices:
#1 UUID: 346D6B0CF5B8446D9BEFF2078EC9BFDF, RSSI 0, Server: 0001

Up to here all looks fine

On the PI-2, I try to discover the the un provisioned node active on the PI-1
PI-2 & PI-1 have the same 5.77 bluez stack recompile

On PI-2
Terminal-1
sudo rm -rf ~/.config/meshcfg/config_db.json
sudo rm -fr /root/.config/meshcfg/config_db.json
sudo rm -rf /var/lib/bluetooth/mesh
sudo mkdir /var/lib/bluetooth/mesh
sudo /usr/libexec/bluetooth/bluetooth-meshd -nd --debug

Terminal-2
sudo mesh-cfgclient
create
discover-unprovisioned on
list-unprovisioned
Unprovisioned devices:

====>>>
The problem is that my list-unprovisioned on PI-2 / Terminal-2 does not retrieve anything

I see nevertheless, on PI-2 (see meshd logs below) some beacon activity, but I don't understand why I can get them on the list-unprovisioned

Thanks very much for your support
Regards
