Test control messages have no effect

Hi,
deactivate sending control msgs in the manual_control client, and then it works ;-)

@fabianoboril Hi, I just tried what you suggested, it does disable the keyboard but the control command is still not working. Any hints on how to solve it? Thanks!
An interesting observation: if I send an unreasonably high steering angle, the ros bridge indicates an error: [ERROR] [1547232927.476727, 708.026874]: Max steering angle reached, clipping value
This means that the bridge is accepting the command, but they just don't have any effect on the vehicle.

Hi,
are you publishing the ackermann msg as described in the README, i.e.
rostopic pub /carla/ego_vehicle/ackermann_cmd ackermann_msgs/AckermannDrive "{steering_angle: 0.0, steering_angle_velocity: 0.0, speed: 10, acceleration: 0.0, jerk: 0.0}" -r 10

Do you use the rosbridge with the PID controller mode, or with throttle/brake input mode? (See https://github.com/carla-simulator/ros-bridge/blob/master/config/settings.yaml --> controlmode)?

Can you provide the data published via the ego_vehicle_control_info topic? Thank you.

Hi,
and maybe try PR #31 ;-)

[yangydavid]

The PR helped. Thanks

I can't find the solution to #31 Could you send me a screenshot of it because I encountered the same problem which is there is no control of the ego_vehicle after type in the Ackermann_control command.
