Joystick control cuts out

[shawnhanna]

Joystick control, even when we are standing near the robot, often will cut out.

It appears to be worst when running w/o moving your fingers at all (i.e. not updating the throttle values, I assume?)

I haven't yet tried playing too much with the update rate option. Maybe it needs to be set lower

I'm not sure about outside of my branches, but this is a "feature" in the phone server, not the tablet. It isn't cutting out. Any time you press the joystick, the function that runs on the phone server in response starts a "time out" of sorts. If the phone does not receive new joystick inputs, it sets the signals to zero. This prevents a runaway condition.

I think Chris removed this some time ago in a cleanup branch, but I never incorporated that change into my branches.

Maybe I'm misunderstanding this but the tablet joystick is constantly sending out values when the joystick is not at origin. So shouldn't the phone constantly be getting twist values so it doesnt time out?

Oh I'm wrong.

Only when its moved does it update the thrust and rudder. We should should switch to a joystick listener to uses the MotionEvent.ACTION_DOWN instead of ACTION_MOVE so it constantly runs while youre holding the joystick.

I fixed this in a commit somewhere... Sincerely, Christopher Tomaszewski (973) 641-0694
