[Java-player-users] P/S 2.1, Javaclient2 and PTZInterface

[Maria S. <mar...@go...>]

Hi,

I think I've read similar questions on the list but no answers to them 
so I try again:

I understood that P/S 2.1 and Javaclient are to some extend but not 
fully compatible, right!?
So with these software versions I simply try to control a pan-tilt-unit. 
My problem is that I can read from the ptz once, then move it to a 
desired position and then I can never read from it again, it loops 
forever... surely this can't be a version problem!?

Here's the (very simple) code:


/        // read actual position data
        System.out.println(robot.readAll());
                   
        while (!head.isDataReady()) {           
            robot.readAll();
        }
       
        PlayerPtzData data = head.getData();
       
        float acttilt = data.getTilt();
        float actpan = data.getPan();

        System.out.println("actual pos ["+actpan+","+acttilt+"]");
        System.out.println("moving to ["+pangoal+","+tiltgoal+"]");

        // create a data structure that contains new position data and 
pass to ptz-interface
        PlayerPtzCmd direction = new PlayerPtzCmd();

        direction.setPan(pangoal);
        direction.setTilt(tiltgoal);
      
        head.setPTZ(direction);

        // now read new/actual position data
        System.out.println(robot.readAll());
       
        while (!head.isDataReady()) {   
            robot.readAll();
        }
       
        PlayerPtzData nextData = head.getData();
        actpan = nextData.getPan();
        acttilt = nextData.getTilt();
        System.out.println("final pos ["+actpan+","+acttilt+"]");
/


If anyone can help me here, that would be great.

Thanks,
Maria

As you allready know, P/S2.1 and the actual Javaclient are not compatible at
all. The messages sent by the PS server have been modified since 2.0.5 so
the javaclient proxies are trying to decode diferent size messages. This
leads to strange behaviours, basically due to the fact that javaclient is
unable to decode those messages.

I guess you can read and send the first command but no more because somehow
those messages have not been changed, or at least not too much, but this is
a lotery ...

We will release a new version ASAP, but unfortunately right now we simply
have no more than 24 hours a day. We are trying to get 36h/day days but days
are not cooperating ... ;)

Bests
Leo

Hi Leo,
many thanks for your reply!
Before I got your message I somehow managed to control the PTZ and 
bascially set it to any position I want, though it still is impossible 
to read from it. Well, for my purposes that was sufficient... though of 
course it is not satisfactory state at all.
I'm sure you guys work very hard on the new version, so many thanks for 
that in advance! I just thought I'd let you know what effects I noticed 
so far...
cheers, maria
