Hi,

Im trying to unravel the problem I have with communicating with the ardrone using ardrone_automation.

I have the ardone connected via wifi and it is visable, no ethernet connected. I have had the ardone running on this computer previously using another application (closed long ago). Drone is on and connected via wifi.

When I try to communicate I get:

nigel@nigel-Satellite-P100:~$ rosnode list

ERROR: Unable to communicate with master!

I have installed all the program as per your instructions and when I go to run it I get the following problem:

nigel@nigel-Satellite-P100:~$ rosrun ardrone_autonomy ardrone_driver

Wait authentification

===================+> 192.168.1.1

This is my hosts file: 127.0.0.1 localhost

127.0.1.1 nigel-Satellite-P100

The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback

fe00::0 ip6-localnet

ff00::0 ip6-mcastprefix

ff02::1 ip6-allnodes

ff02::2 ip6-allrouters

I think I made it worse using:

$ export ROS_HOSTNAME=localhost

$ export ROS_MASTER_URI=http://'localhost:11311' ('added so as not to post link')

Please help !
