Pyconman demo.py throwing error when establishing a new connection.
Hello, I am facing an issue when running pyconnman demo example.
Error ( With try catch block in demo.py at service_connect() function ) :-
Unable to complete: (<class 'dbus.exceptions.DBusException'>,

did not send a reply, the message bus security policy blocked the reply, the reply
timeout expired, or the network connection was broken.',), <traceback object at 0xb6002b70>)

Where the connection has already been established previously It's working for the Python Demo Script.
It's throwing the error for establishing a new connection.
Also When I use connmanctl for the Same network it's working without any problem.
PyPI version out of date
The version of pyconnman hosted on PyPI does not contain the latest fixes. Most notably the dependency on python-dbus is missing.
Change properties with pyconnman
Hi,
For a project I would like to use pyconnman to read and write the Ethernet properties.
On this moment I am able to read the properties with pyconnman, but I am not able to write new values.
For example how can I change the Gateway and IP address of an IPv4 connection?
The current code I tried is:
service = pyconnman.service.ConnService('/net/connman/service/ethernet_00142d63183c_cable')
ip = service.get_property('IPv4')
ip_conf = service.get_property('IPv4.Configuration')
print(service.get_property('IPv4'))
ip.update({dbus.String('Gateway'): dbus.String('192.168.10.222')})
ip_conf.update({dbus.String('Gateway'): dbus.String('192.168.10.222')})
ip_conf.update({dbus.String('Address'): dbus.String('192.168.10.240')})
ip.update({dbus.String('Address'): dbus.String('192.168.10.240')})
But this has no effect on the Ethernet properties. When I check with connmanctl the properties are not affected.
Thank you in advance for your help.
Best regards,
Gerard
Release for Python 3
Hi,
are you gonna make a release on pypi to include the python3 support?
Cheers

Not working when connecting for the first time?
I'm running into an issue when using the demo.py example or my own script and connecting to a wifi network for the first time. For example:
CONN> list-services
CONN> agent-start /test/agent ssid=myNetwork passphrase=myPassphrase
CONN> service-connect /net/connman/service/wifi_xxxxx__managed_psk
This eventually results in an error:
Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken
However, if I use connmanctl to manually connect at least once, it does work. For example:
connmanctl connmanctl> agent on
connmanctl> connect wifi_xxxxx__managed_psk Agent RequestInput wifi_xxxxx__managed_psk
Passphrase = [ Type=psk, Requirement=mandatory ] Passphrase? myPassword
connmanctl> Connected wifi_xxxxx__managed_psk
Now it will connect, and I can use the same demo.py script to disconnect or reconnect. But for any new wifi network, I have to use connmanctl first (which creates the /var/lib/connman/wifi* folder with the saved settings)
Any idea why this would be the case and how I might get around the problem?
Invalid Arguements
I've been trying to resurrect this code and I'm having trouble using the agent to get WPA connections working. I've been able to successfully use the node.js version of connman so I know it's not the network. I'm getting an Invalid Arguments as described here: https://github.com/liamw9534/pyconnman/blob/master/pyconnman/service.py#L421, but I don't know what arguments would be invalid. I've logged just about everything and when a Passcode is requested, it properly responds with the correct passcode, it just seems to be in an invalid format. Any thoughts or advice would be much appreciated!
add dependency on dbus-python
When installing via pip, I need to also install dbus-python or I cannot import pyconnman. It would be convenient to just add that dependency in setup.py. I can make a pull request if you like.
