msgpack not working with AWS

[ShawnSchaerer]

found that msgpack would fail when sending data to topics using AWS and mosquito client locally. I had to change the code to

msg_dict = self._deserialize(mqtt_msg.payload)

msg_dict = json.loads(mqtt_msg.payload)

in _create_ros_message(self, mqtt_msg):

Have you seen this? I am willing to do a PR on this

@ShawnSchaerer Sorry for replying late. You can use json as a serializer/deserializer by specifying it in config file (or rosparam) like following.

serializer: json:dumps
deserializer: json:loads

Or you can just comment out this setting. Json is a default serializer for mqtt_bridge.
