Sure, here's a Python program that you can use on your Raspberry Pi Pico W to check for MQTT messages. It uses the `umqtt.robust` library to connect to an MQTT broker, subscribes to a topic, and listens for incoming messages. When a message is received, it sets the LED on for one second. In the loop, it also blinks the LED to indicate that it's polling. Make sure you have the `umqtt.robust` library installed on your Pico W. You can install it using the `upip` package manager.

import machine
import time
import ubinascii
from umqtt.robust import MQTTClient

# LED Setup
led = machine.Pin("LED", machine.Pin.OUT)

# WiFi Setup
# Replace with your WiFi credentials
WIFI_SSID = "YOUR_WIFI_SSID"
WIFI_PASSWORD = "YOUR_WIFI_PASSWORD"

# MQTT Setup
MQTT_SERVER = "YOUR_MQTT_BROKER_ADDRESS"
CLIENT_ID = ubinascii.hexlify(machine.unique_id())
TOPIC = "YOUR_TOPIC"

# Connect to WiFi
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect(WIFI_SSID, WIFI_PASSWORD)
while not wlan.isconnected():
    pass
print("Connected to WiFi")

# MQTT Callback
def mqtt_callback(topic, msg):
    print(f"Received message from {topic}: {msg}")
    led.value(1)  # Set LED on
    time.sleep(1)  # Keep LED on for 1 second
    led.value(0)  # Set LED off

# Connect to MQTT Broker
client = MQTTClient(CLIENT_ID, MQTT_SERVER)
client.set_callback(mqtt_callback)
client.connect()
client.subscribe(TOPIC)
print(f"Subscribed to {TOPIC}")

while True:
    client.check_msg()  # Check for incoming MQTT messages
    led.value(not led.value())  # Toggle LED
    time.sleep(0.5)  # Wait for 0.5 seconds

Here's how the program works: 1. It imports the necessary libraries and sets up the LED pin. 2. It connects to your WiFi network using the provided SSID and password. 3. It sets up the MQTT client with the broker address, a unique client ID, and the topic to subscribe to. 4. The `mqtt_callback` function is defined, which will be called when a message is received. It prints the message and sets the LED on for one second. 5. The program connects to the MQTT broker and subscribes to the specified topic. 6. In the main loop, it calls `client.check_msg()` to check for incoming MQTT messages. If a message is received, the `mqtt_callback` function will be called. 7. The LED is toggled in each iteration of the loop to indicate that the program is polling. 8. The program sleeps for 0.5 seconds before the next iteration of the loop. Make sure to replace `YOUR_WIFI_SSID`, `YOUR_WIFI_PASSWORD`, `YOUR_MQTT_BROKER_ADDRESS`, and `YOUR_TOPIC` with your actual WiFi credentials, MQTT broker address, and the topic you want to subscribe to, respectively. Note: This program assumes that you have the `umqtt.robust` library installed on your Pico W. If you don't have it installed, you can install it using the `upip` package manager. Connect your Pico W to a computer, open the Thonny IDE, and run the following command in the Thonny Shell:

import upip
upip.install("umqtt.robust")

Here's a Python program that you can use on your Raspberry Pi Pico W to check for MQTT messages. It uses the `pico-mqtt` library for MQTT communication and the built-in `machine` module to control the LED. The program runs in a non-blocking manner and blinks the LED on every loop iteration to indicate that it's polling. When it receives a message, it sets the LED solid for one second.

import time
import machine
import umqtt.robust as mqtt

# Configure MQTT client
mqtt_client = mqtt.MQTTClient(
    client_id="pico-client",
    server="broker.example.com",
    user="username",
    password="password",
    keepalive=60,
)

# LED pin
led = machine.Pin(25, machine.Pin.OUT)

# MQTT callback function
def on_message(topic, message):
    print(f"Received message on topic {topic}: {message}")
    led.value(1)  # Turn LED on
    time.sleep(1)  # Keep LED on for 1 second
    led.value(0)  # Turn LED off

# Connect to MQTT broker
mqtt_client.set_callback(on_message)
mqtt_client.connect()
mqtt_client.subscribe(topic="your/topic/here")

while True:
    led.value(not led.value())  # Toggle LED
    mqtt_client.check_msg()  # Check for incoming messages
    time.sleep(0.5)  # Adjust delay as needed

Here's a breakdown of the code: 1. Import necessary modules: `time` for time-related functions, `machine` for hardware control, and `umqtt.robust` for MQTT communication. 2. Configure the MQTT client with the appropriate broker address, credentials, and keep-alive interval. 3. Define the LED pin using `machine.Pin(25, machine.Pin.OUT)`. 4. Define an MQTT callback function `on_message` that prints the received message and sets the LED solid for one second when a message is received. 5. Connect to the MQTT broker using `mqtt_client.connect()` and subscribe to the desired topic using `mqtt_client.subscribe(topic="your/topic/here")`. 6. Enter an infinite loop that toggles the LED on every iteration to indicate polling and checks for incoming MQTT messages using `mqtt_client.check_msg()`. The `time.sleep(0.5)` adjusts the polling interval (adjust as needed). Make sure to replace `"broker.example.com"`, `"username"`, `"password"`, and `"your/topic/here"` with the appropriate values for your MQTT broker and topic. Note: This code assumes you have the `pico-mqtt` library installed on your Raspberry Pi Pico W. If not, you can install it using the Thonny IDE or by following the instructions in the [pico-mqtt GitHub repository](https://github.com/pypico/pico-mqtt).

Sure, here's a Python program that you can run on your Raspberry Pi Pico W to check for MQTT messages. It uses the `umqtt.simple` module from the MicroPython library to connect to an MQTT broker, subscribe to a topic, and receive messages. Additionally, it blinks the on-board LED on every loop iteration to indicate that it's polling, and sets the LED to solid for one second when a message is received.

import machine
import time
import network
import umqtt.simple

# Set up WiFi connection
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect('YOUR_WIFI_SSID', 'YOUR_WIFI_PASSWORD')
while not wlan.isconnected():
    pass
print("Connected to WiFi")

# Set up MQTT client
mqtt_client = umqtt.simple.MQTTClient(client_id="pico_mqtt_client", server="YOUR_MQTT_BROKER_IP", keepalive=60)

# Set up LED
led = machine.Pin(25, machine.Pin.OUT)

def on_message(topic, message):
    print(f"Received message on topic: {topic}, message: {str(message)}")
    led.value(1)  # Turn LED on
    time.sleep(1)  # Keep LED on for 1 second
    led.value(0)  # Turn LED off

def connect_and_subscribe():
    mqtt_client.set_callback(on_message)
    mqtt_client.connect()
    mqtt_client.subscribe("YOUR_TOPIC")

def main():
    connect_and_subscribe()
    while True:
        led.value(not led.value())  # Blink LED
        time.sleep(0.5)  # Delay between LED blinks
        mqtt_client.check_msg()  # Check for incoming MQTT messages

if __name__ == "__main__":
    main()

Here's what the code does: 1. It sets up a WiFi connection using the `network` module and connects to your WiFi network using your SSID and password. 2. It sets up an MQTT client using the `umqtt.simple` module and connects to your MQTT broker with your broker IP address. 3. It initializes the on-board LED (GPIO 25) using the `machine` module. 4. It defines a callback function `on_message` that is called when a message is received on the subscribed topic. This function prints the received message and turns the LED on for one second. 5. The `connect_and_subscribe` function sets the callback function for the MQTT client, connects to the broker, and subscribes to the specified topic. 6. The `main` function calls `connect_and_subscribe`, and then enters an infinite loop where it blinks the LED every 0.5 seconds and checks for incoming MQTT messages using `mqtt_client.check_msg()`. Make sure to replace the following placeholders with your actual values: - `'YOUR_WIFI_SSID'` with your WiFi SSID - `'YOUR_WIFI_PASSWORD'` with your WiFi password - `'YOUR_MQTT_BROKER_IP'` with the IP address of your MQTT broker - `'YOUR_TOPIC'` with the MQTT topic you want to subscribe to Note that this code assumes you have the MicroPython firmware installed on your Raspberry Pi Pico W, and the necessary libraries (`umqtt.simple` and `machine`) available. You may need to install additional libraries or adjust the code depending on your specific setup and requirements.

Here's a Python program that you can run on your Raspberry Pi Pico W to check for MQTT messages, blink an LED on every loop iteration, and set the LED solid for a second when a message is received:

import machine
import utime
from umqtt.robust import MQTTClient

# Set up the LED pin
led = machine.Pin(25, machine.Pin.OUT)

# MQTT broker details
BROKER = "broker.example.com"
PORT = 1883
CLIENT_ID = "pico-client"
TOPIC = "my/topic"

# Connect to the MQTT broker
client = MQTTClient(CLIENT_ID, BROKER, PORT)
client.connect()
client.set_callback(on_message_received)
client.subscribe(TOPIC)

def on_message_received(topic, message):
    print(f"Received message: {message} on topic: {topic}")
    led.value(1)  # Set LED on
    utime.sleep(1)  # Keep LED on for 1 second
    led.value(0)  # Set LED off

def poll_mqtt():
    client.check_msg()  # Check for incoming MQTT messages
    led.value(not led.value())  # Toggle LED
    utime.sleep_ms(100)  # Delay for 100ms

while True:
    poll_mqtt()

Here's how the program works: 1. Import the necessary modules: `machine` for controlling the LED, `utime` for delays, and `umqtt.robust` for the MQTT client. 2. Set up the LED pin (25) as an output. 3. Define the MQTT broker details: hostname, port, client ID, and topic to subscribe to. 4. Connect to the MQTT broker, set the callback function for incoming messages, and subscribe to the specified topic. 5. The `on_message_received` function is called when a message is received. It prints the message and topic, sets the LED on for 1 second, and then turns it off. 6. The `poll_mqtt` function checks for incoming MQTT messages using `client.check_msg()`, toggles the LED state, and adds a delay of 100ms. 7. The main loop calls the `poll_mqtt` function repeatedly. Make sure to replace `"broker.example.com"` with the hostname or IP address of your MQTT broker, and `"my/topic"` with the topic you want to subscribe to. Note: This code assumes that you have the `umqtt.robust` library installed on your Raspberry Pi Pico W. If not, you can install it using the Thonny IDE or upload the library files to your Pico's filesystem.

Sure, here's a Python program that you can run on your Raspberry Pi Pico W to check for MQTT messages. It will blink an LED on every loop iteration and set the LED solid for a second when it receives a message:

import network
import ubinascii
import machine
import time
import random
from umqtt.simple import MQTTClient

# WiFi credentials
SSID = "YOUR_WIFI_SSID"
PASSWORD = "YOUR_WIFI_PASSWORD"

# MQTT broker details
BROKER = "YOUR_MQTT_BROKER_IP"
CLIENT_ID = ubinascii.hexlify(machine.unique_id())

wlan.connect(SSID, PASSWORD)
while not wlan.isconnected():
    pass
print("Connected to WiFi")

# MQTT callback function
def on_message(topic, msg):
    print("Received message: {}".format(msg))
    LED.value(1)  # Set LED solid for a second
    time.sleep(1)
    LED.value(0)

# MQTT client setup
client = MQTTClient(CLIENT_ID, BROKER)
client.set_callback(on_message)
client.connect()
client.subscribe(TOPIC)
print("Subscribed to MQTT topic: {}".format(TOPIC))

# Main loop
while True:
    LED.value(not LED.value())  # Blink LED
    time.sleep(0.5)  # Wait for 0.5 seconds
    client.check_msg()  # Check for MQTT messages

Here's how the program works: 1. First, you need to set your WiFi credentials (`SSID` and `PASSWORD`) and MQTT broker details (`BROKER` and `TOPIC`). 2. The program connects to the WiFi network using the `network` module. 3. An MQTT client is set up using the `umqtt.simple` module. The `on_message` function is defined to handle incoming MQTT messages. 4. The LED pin (GPIO 25) is set up using the `machine` module. 5. In the main loop, the program blinks the LED and checks for MQTT messages using `client.check_msg()`. 6. When an MQTT message is received, the `on_message` function is called, and it sets the LED solid for one second. Make sure to replace `YOUR_WIFI_SSID`, `YOUR_WIFI_PASSWORD`, `YOUR_MQTT_BROKER_IP`, and `YOUR_TOPIC` with your actual values. Note: This program uses the `umqtt.simple` module, which is part of the MicroPython firmware for the Raspberry Pi Pico W. If you're using a different version of MicroPython or a different board, you may need to use a different MQTT library or make minor modifications to the code.
