SSID = "NETGEAR84"
PASSWD = ""

def do_connect():
sta_if = network.WLAN(network.STA_IF)
if not sta_if.isconnected():
print("connecting to network.....")
sta_if.active(True)
sta_if.connect(SSID, PASSWD)
while not sta_if.isconnected():
pass
print("network config:",sta_if.ifconfig())


do_connect()


SERVER = "192.168.1."
CLIENT_ID = "ESP8266"
TOPIC = "t_h"


client = MQTTClient(CLIENT_ID,SERVER)
client.connect()

d = dht.DHT22(machine.Pin(14))

These files arfe not always included in the build. You can find them in the micropython-lib:

https://github.com/micropython/micropyt ... /robust.py
https://github.com/micropython/micropyt ... /simple.py

You have to create a directory name umqtt on you board and copy these files to that directory. I do not know, which board you are using, so the method for copying varies.

you also need to create a __init__.py in that umqtt folder (an empty file).

I created the mqtt folder inside the esp8266 in the folder I inserted the empty __init__.py file but after doing this it is as if the card had stopped working to connect to the card I use the picocom command from the mac terminal but doing so now gives me terminal ready but no I can write nothing and if I press the reset button on the board it does not reset correctly because it no longer executes the two files boot.py and main.py if I did it before the creation of __init__.py everything worked correctly I already tried to clear the memory of the card and reinstall micropython but nothing has changed what could have happened?
