Hi everyone. I am trying to use Matlab with MavRos inorder to command a drone in Gazebo. The drone is equipped with a virtual Pixhawk oard running PX4. I can retrieve information aout some sensors. My problem is I cannot call the rosservices. Matlab has Rosservice function. It implements 'list', info', 'type' and 'url' but not 'call', the most important to me. Can I bypass the problem? Thanks

Hello Luca,
The rosservice function is designed to give introspection information from the network about available services. For actual setting up of service clients and servers, you can use the rossvcclient and rossvcserver functionality. See here for a comprehensive example.

Hi,
The docs don't mention how to call a service, they just mention the following:
- Create a service server
- Create a service client
For example a service that already exist is called /mavros/cmd/arming
What I normally do is
- rospy.wait_for_service('/mavros/cmd/arming')
- armService = rospy.ServiceProxy('/mavros/cmd/arming', mavros_msgs.srv.CommandBool)
- armService(True)
Any idea on how to do it in MATLAB?

See the last link I provide in my answer, when they call the "call" function. This is what performs the actual service call. In MATLAB, the call to services is synchronous, so there is no need to "wait for" it to complete.
