wow should i use mip.install? (trying to connect with adafruit server whith a micropython board)

[camp-easy]

hi everyone, im using this code to make callback whit mqtt broker with adafruit server :

import cellular
import machine
import time

cellular.gprs("", "", "") # ("apn_name","username","password")

led_topic = "/feeds/stato"
sensor_topic = "/feeds/temperature"

led = machine.Pin(27,machine.Pin.OUT)

time_period = 6

Import mqtt (download client if necessary)

try:
from umqtt import simple
except ImportError:
import mip
mip.install("micropython-umqtt.simple")
from umqtt import simple

def cb(led_topic, msg): # Callback function
print('Received Data: Topic = {}, Msg = {}'.format(led_topic, msg))
recieved_data = str(msg,'utf-8') # Recieving Data
if recieved_data=="0":
led.value(0)
if recieved_data=="1":
led.value(1)

Report location

name = "a9g-micropython-board"
server = "io.adafruit.com"
port = 1883
username = ""
password = ""

client = simple.MQTTClient(name, server, port, username, password )
client.connect()

client.set_callback(cb) # Callback function
client.subscribe(led_topic) # Subscribing to particular topic

def send_sensor():
msg = "100"
print('Sending Data: Topic = {}, Msg = {}'.format(sensor_topic, msg))
client.publish(sensor_topic, msg)

while True:
for x in range(time_period):
for x in range(10):
client.check_msg()
time.sleep(0.1)
send_sensor()

but it's not working and i receive thi serror:

OSError: [Errno 110] ETIMEDOUT

does anyone know how to fix that? thank you in advance for the support

Please enclose code in triple backticks ("`" characters). That preserves indentation. Then show the traceback which will tell us which line of code is causing the error.

Lastly please don't spam multiple messages about the same problem. I and others have already explained that the line

mip.install("micropython-umqtt.simple")

is incorrect, e.g. here and here.
