Hi,
\n
I can set the IP etc on my interface and apply to the bus:
\n
        from sdbus_async.networkmanager import NetworkManagerSettings, NetworkConnectionSettings\n\n# Ideally want to look up by device eth1\n        connection_paths = await NetworkManagerSettings().get_connections_by_id(self.connection_id)\n        if not connection_paths:\n            raise Exception(f\"No connection found with id {self.connection_id}\")\n\n        connection_manager = NetworkConnectionSettings(connection_paths[0])\n        connection_profile = await connection_manager.get_profile()\n        settings = connection_profile.to_settings_dict()\n        \n        return settings, connection_manager\n\nasync def _network_linux_apply(self):\n        from sdbus_async.networkmanager.settings import ConnectionProfile\n        settings, connection_manager = await self._network_linux_profile()  \n        ipv4 = settings['ipv4']\n        ipv4['address-data'][0]['address'] = self.ap_ip\n        ipv4['address-data'][0]['prefix'] = sum([bin(int(x)).count('1') for x in self.netmask.split('.')])\n        ipv4['gateway'] = self.gateway\n        ipv4['dns-data'][0] = self.dns \n        new_connection_profile = ConnectionProfile.from_settings_dict(settings)\n        await connection_manager.update(new_connection_profile.to_dbus())\n        await connection_manager.save()\n\n
\n
However to get the device to use the new IP, I have to issue nmcli connection up 'Wired connection 2'
\n
How can this command by sent via the python AP?
\n
Thanks in advance

Thanks so much .. that did the job! You don't need to deactivate on the linux I'm using.

Here is the update code should anyone else need it:
\n
    async def _network_linux_apply(self):\n        from sdbus_async.networkmanager.settings import ConnectionProfile\n        settings, connection_manager = await self._network_linux_profile()  \n        ipv4 = settings['ipv4']\n        ipv4['address-data'][0]['address'] = self.ap_ip\n        ipv4['address-data'][0]['prefix'] = sum([bin(int(x)).count('1') for x in self.netmask.split('.')])\n        ipv4['gateway'] = self.gateway\n        ipv4['dns-data'][0] = self.dns \n        new_connection_profile = ConnectionProfile.from_settings_dict(settings)\n        await connection_manager.update(new_connection_profile.to_dbus())\n\n        from sdbus_async.networkmanager import NetworkManagerSettings, NetworkManager\n        connection_paths = await NetworkManagerSettings().get_connections_by_id(self.connection_id)\n        await nm.activate_connection(connection_paths[0])\n
