Subscribtion fail

[yacineTazerout]

Hi, am trying to subscribe to a Niryo simulator ros topic "/niryo_robot_hardware_interface/hardware_status" , i write a code following the RosSharp subscibers, but i am not able to get any result, i verified the subscribers with "rostopics info" and i found that i don't even subscribe, i tried to do an rostopic echo, and the ros a correctly publishing into the topic, i tried also pynirio to test if it's possible to get the HardwareStatus with it, and yes no problem with that.

Here is my question: So my question is , is the code bellow wrong, do you encoutered the same problem, do you have any suggestion or sollution

I am using the latest ROS# version available here on the master branch.

• My OS is:
• My Unity Version is: 2020.3.19f
• My ROS Distribution is: Melodic
• My Build Target Platform is: Windows, Android

Relevant Code:

using RosSharp.RosBridgeClient;
using RosSharp.RosBridgeClient.MessageTypes.NiryoRobot;
using UnityEngine.UI;

public class HardwarestatusSubscriber : UnitySubscriber<HardwareStatus>
{

    public Text text;
    public int temp;
    public bool isRecieved;

    protected override void Start()
    {
        base.Start();
    }

    protected override void ReceiveMessage(HardwareStatus message)
    {
        isRecieved = true;
        temp = message.temperatures[0];
    }
}

And this is the HardwareStatus msg :

using RosSharp.RosBridgeClient.MessageTypes.Std;

namespace RosSharp.RosBridgeClient.MessageTypes.NiryoRobot
{
    public class HardwareStatus : Message
    {
        public const string RosMessageName = "niryo_robot_msgs/HardwareStatus";

        public Header header { get; set; }
        //  Raspberry Pi board
        public int rpi_temperature { get; set; }
        //  Ned, One, ....
        public string hardware_version { get; set; }
        //  Hardware State
        public const sbyte ERROR = -1;
        public const sbyte NORMAL = 0;
        public const sbyte DEBUG = 1;
        public const sbyte REBOOT = 2;
        public sbyte hardware_state { get; set; }
        //  Motors
        public bool connection_up { get; set; }
        public string error_message { get; set; }
        public bool calibration_needed { get; set; }
        public bool calibration_in_progress { get; set; }
        public string[] motor_names { get; set; }
        public string[] motor_types { get; set; }
        public int[] temperatures { get; set; }
        public double[] voltages { get; set; }
        public int[] hardware_errors { get; set; }
        public string[] hardware_errors_message { get; set; }

        public HardwareStatus()

        {
            this.header = new Header();
            this.rpi_temperature = 0;
            this.hardware_version = "";
            this.hardware_state = 0;
            this.connection_up = false;
            this.error_message = "";
            this.calibration_needed = false;
            this.calibration_in_progress = false;
            this.motor_names = new string[0];
            this.motor_types = new string[0];
            this.temperatures = new int[0];
            this.voltages = new double[0];
            this.hardware_errors = new int[0];
            this.hardware_errors_message = new string[0];
        }

        public HardwareStatus(Header header, int rpi_temperature, string hardware_version, sbyte hardware_state, bool connection_up, string error_message, bool calibration_needed, bool calibration_in_progress, string[] motor_names, string[] motor_types, int[] temperatures, double[] voltages, int[] hardware_errors, string[] hardware_errors_message)
        {
            this.header = header;
            this.rpi_temperature = rpi_temperature;
            this.hardware_version = hardware_version;
            this.hardware_state = hardware_state;
            this.connection_up = connection_up;
            this.error_message = error_message;
            this.calibration_needed = calibration_needed;
            this.calibration_in_progress = calibration_in_progress;
            this.motor_names = motor_names;
            this.motor_types = motor_types;
            this.temperatures = temperatures;
            this.voltages = voltages;
            this.hardware_errors = hardware_errors;
            this.hardware_errors_message = hardware_errors_message;
        }
    }
}
