Unfortunately, there is no support for wildcards at the moment. I'm guessing that implementation shouldn't be too hard, but right now, you would need to specify all topics in advance. However, you could probably just pre-specify more topics than you would ever need without affecting performance too much, I guess. |

In my project I need to map telemetry data from multiple MQTT topics to corresponding ROS topics. Each drone publishes its data to a unique MQTT topic (e.g., fleet/drone1/telemetry, fleet/drone2/telemetry , etc.). My goal is to bridge these MQTT topics to corresponding ROS topics (e.g., /drone1/telemetry, /drone2/telemetry) without knowing the number of drones in advance.
Config file:
Do I need to manually specify every single topic or is it possible to use wildcards (+) to dynamically subscribe to topics like fleet/+/telemetry ?
