2023-03-17 18:20:02 -0500 | marked best answer | [ROS2] asyncio await with timeout a service call in a callback Hi! I am trying to use the asyncio syntax to await for a service to complete inside a callback function of a Node. A dummy node to test this: You can test it with That code works just fine. The callback function doesn't block any other callback functions and it returns the result of the service. Now If I want to add a timeout to that future with I tried everything, spawning a new event_loop in a separate thread, calling I tried this alternative approach: Now I get the error: Does anyone know how to handle this? Any asyncio and rclpy expert for advice? I want to stick with a Singlethreaded executor [UPDATE] PD: If I use the async_timeout package and the alternative approach for spinning the node it works, but I still don't want to depend on an external package |
