The .srv file syntax is basically unchanged, but we do have to modify the definition. Since ROS2 does not allow you to return a boolean from a service callback, we must track success and failure ourselves. Add a success member to the response in LocalizePart.srv:In ROS1, it was possible to make a (synchronous) service call from a callback. In ROS2, in a derived node class, if I do the following: create a service client using "create_client" within a callback function (e.g. a timer callback) call async_send_request() on the client and then: call get() on the future that is returned It will block forever.I want to get a native rti DDS 5.3.1 application running with ROS2 eloquent.
