# MQTT Example. # This example shows how to use the MQTT library to publish to a topic. # # 1) Copy the mqtt.py library to OpenMV storage. # 2) Run this script on the OpenMV camera. # 3) Install the mosquitto client on PC and run the following command: # mosquitto_sub -h test.mosquitto.org -t "openmv/test" -v # # NOTE: If the mosquitto broker is unreachable, try another broker (For example: broker.hivemq.com) import time, network from mqtt import MQTTClient SSID='' # Network SSID KEY='' # Network key # Init wlan module and connect to network print("Trying to connect... (may take a while)...") wlan = network.WINC() wlan.connect(SSID, key=KEY, security=wlan.WPA_PSK) # We should have a valid IP now via DHCP print(wlan.ifconfig()) client = MQTTClient("openmv", "test.mosquitto.org", port=1883) client.connect() while (True): client.publish("openmv/test", "Hello World!") time.sleep(1000)
