Listen_event not trigger

[m.arthur]

Hi, I am trying to use the listen_event to get the camera capabilities when the app connect to the drone. however, the listener is never trigger. below is my code snippet, could you help to take a look? thanks!!

import time
import os
import olympe
from olympe.messages import camera

olympe.log.update_config({"loggers": {"olympe": {"level": "INFO"}}})
DRONE_IP = os.environ.get("DRONE_IP", "192.168.53.1")

def print_event(event):
    if isinstance(event, olympe.ArsdkMessageEvent):
        max_args_size = 60
        args = str(event.args)
        args = (args[: max_args_size - 3] + "...") if len(args) > max_args_size else args
        print(f"{event.message.fullName}({args})")
    else:
        print(str(event))


class CameraCapabilitiesListener(olympe.EventListener):
    @olympe.listen_event(camera.camera_capabilities())
    def onCameraCapabilities(self, event, scheduler):
        print_event(event)

def test_listener():
    drone = olympe.Drone(DRONE_IP)
    

    with CameraCapabilitiesListener(drone) as listener:
        drone.connect()
        time.sleep(100)

if __name__ == "__main__":
    test_listener()

Hi,

Only event messages may be monitored with a listener. The camera.capabilities message you are using here is part of the camera2.Event.State event message that you should be using instead.

Thank you for your reply. Do you mean I should use camera2.Event.State instead? however, we are using anafi and anafi thermal, does camera2 feature also support these two models?
