[JdeRobot] Problems using real Ardrone2.0

[Francisco Pérez]

Hi Javier,

Just to clarify how to launch this example, I give you all the steps you
must follot o make the real ArDrone example works:

1. Plug the battery in the ArDrone. It will automaticaly generate a custom
wifi network called ardrone_xxxx.

2. Bind your pc to that network, you will be now connected to your drone.
(NOTE: you will lose your internet connection, just for the record)

3. Once connected, you have to launch the ardroneserver component, as you
did:



and take note of the bindings made in the server side. To do that, open the
ardrone_interfaces.cfg file and look at the endpoints (don't pay attention
to the 'ws' part):



Those ports are required for the client side binding. You can see that each
interface binds to a different port, so let's take a look at the client
side.

4. Open the configuration file of the client tool, in our case
uav_viewer.cfg and check if the ports are correct. 



You must ensure that the endopoints match with the server side
(ardrone_interfaces.cfg). By default it does, but check them to be sure :)

Once you are sure that all the configuration files are ok, you can procceed
to launch the client.



and it should work.

The exception you are pointing out is rising because the server side didn't
connect properly, or just because you have a bad configuration of your .cfg
files. Please, check if you did all the steps above and let us know if you
face the same (or other) problems.

Cheers!
