[Playerstage-users] GPS Proxy does not return data.

[Brandon S. <si...@sp...>]

When I suscribe to the GpsProxy gps(&robot, 0, 'r');

and I use:

robot.Read();

gps.Print();

All of the data shows up as zeroes, even though I can verify that the
numbers are not zero on the driver side.

What would cause this to occur?

The one thing I can think of is that I wrote a position and gps
multi-driver, so possibly the id's are getting mixed up when I use the
PutData() function?

Sincerely,
