Non of those seems suitable to me. The first is the API spec and the other are tests. Maybe raise an issue with the community to see where examples like this could fit?

Good idea !

Thank you! Using this I was also able to turn my Sylvania A19 T-C-MD84F bulb on and off. I was having a lot of trouble provisioning them before, and ended up getting /data/user/0/com.ledvance.smartplus/files/Network_*.meshdata from my phone, so I can use the network that Sylvania's app already created. I used https://github.com/NickstaDB/SerializationDumper/releases/tag/1.13 to extract keys and the device address. Configuring the network to work with that was somewhat complicated. But then I simply started with the test-mesh join step here, and after following these instructions I could simply set the Sylvania bulb as the target and control it.

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 (discover-unprovisioned on)

The discover-unprovisioned on works on PI-1 (like in the above example)
but on PI-2 it returns nothing .....
Same system on both side, same stack, same version

Perhaps I'm not proceeding the right way.
If an expert in the community could help me that would be great !!!

Find below my test case.

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

Hi Vincent, if I remember correctly (which might not be the case), your expectation to see the unprovisioned device on both PIs is not correct. There can be only one "provisioner" on the mesh. By calling "create" on PI2 you are actually creating a new network.

I hope this helps.

dreamlayers commented Sep 30, 2024

Yes, provisioning is the action of joining a device to a network. The device can only be a member of one network at a time. Typically devices can only be discovered unprovisioned when they've been reset, like after rapidly turning a light bulb off and on some number of times. You certainly can use one device from two different computers, but both of those computers must be part of the same network. This can be accomplished by copying the relevant keys from one computer to the other. I did this to control a Sylvania light bulb that had been provisioned via Sylvania's app on my phone. After my computer became part of the same network, I was able to control the light bulb.
