How to get zoom level via DJIBridge
已完成Consider the code:
def on_connect(client, userdata, flags, rc):
print("Connected with result code " + str(rc))
# Subscribing in on_connect() means that if we lose the connection and
# reconnect then subscriptions will be renewed.
client.subscribe("sys/#")
client.subscribe("thing/#")
def on_message(client: mqtt.Client, userdata, msg: mqtt.MQTTMessage):
if msg.topic.endswith("osd") and msg.topic.startswith("thing"):
pprint.pprint(message)
This presents the following output:
