Create Network : Operation failed

[lebrislo]

Hello,

I'm trying since few days to implement a Mesh provisioner with your library for test purpose. According to the bluez mesh-api.txt file the CreateNetwork method is "This is the first method that an application calls to becomea Provisioner node, and a Configuration Client on a newly created Mesh Network."

I tried to do the operation with your library with the following code :

import asyncio
import logging
import secrets

from time import sleep
from bluetooth_mesh.bluez.application import Application, Element, Capabilities
from bluetooth_mesh.crypto import ApplicationKey, DeviceKey, NetworkKey
from bluetooth_mesh.messages.config import GATTNamespaceDescriptor, StatusCode
from bluetooth_mesh.models import ConfigClient, ConfigServer, HealthClient, HealthServer

class PrimaryElement(Element):
    LOCATION = GATTNamespaceDescriptor.MAIN
    MODELS = [
        ConfigClient,
        ConfigServer,
        HealthClient,
    ]

class SampleApplication(Application):
    COMPANY_ID = 0x025E
    PRODUCT_ID = 1
    VERSION_ID = 1
    ELEMENTS = {
        0: PrimaryElement,
    }

    CRPL = 32767
    PATH = "/fr/scheiber/mesh"

    @property
    def dev_key(self):
        return DeviceKey(secrets.token_bytes(16))

    @property
    def net_key(self):
        return 0, NetworkKey(secrets.token_bytes(16))

    @property
    def app_keys(self):
        return {0: ApplicationKey(secrets.token_bytes(16))}


async def main():
    # Set up logging
    logging.basicConfig(level=logging.INFO)

    # Create an event loop
    loop = asyncio.get_event_loop()

    # Create an instance of the Application class
    app = SampleApplication(loop=loop)

    try:
        # Connect to BlueZ
        await app.dbus_connect()

        app.address = 0x0001

        await app.create_network()

    except Exception as e:
        logging.error("Error occurred: %s", e)

# Run the asynchronous function
asyncio.run(main())

When I run the python file I get the following error :

INFO:SampleApplication:Connecting to org.bluez.mesh
INFO:SampleApplication:Registering application
INFO:SampleApplication:Create 5c5e3ef3-3afe-57af-b34a-9c1e9788b431

According the provided code, Do you have any idea how to solve my problem?

Thank you for your reply.
