circuitphyton 5.x and version 3.1.0

I am getting an issue when i update my minimqtt library that i haven't had in the past. the .mpy file gives this error
AttributeError: 'module' object has no attribute 'set_socket'

import adafruit_minimqtt as MQTT
MQTT.set_socket(socket, esp) <-----

if i grab the .py file from GitHub, it works as it should. Do I need to do anything using .mpy file?

@bangell What code.py are you running - could you copy and paste it below?

[bangell]

@brentru, i am using the example minimqtt_adafruitio_wifi.py

import board
import busio
from digitalio import DigitalInOut
import neopixel
from adafruit_esp32spi import adafruit_esp32spi

WiFi

Get wifi details and more from a secrets.py file

try:
from secrets import secrets
except ImportError:
print("WiFi secrets are kept in secrets.py, please add them there!")
raise

If you are using a board with pre-defined ESP32 Pins:

esp32_cs = DigitalInOut(board.ESP_CS)
esp32_ready = DigitalInOut(board.ESP_BUSY)
esp32_reset = DigitalInOut(board.ESP_RESET)

If you have an externally connected ESP32:

esp32_cs = DigitalInOut(board.D9)

esp32_ready = DigitalInOut(board.D10)

esp32_reset = DigitalInOut(board.D5)

spi = busio.SPI(board.SCK, board.MOSI, board.MISO)
esp = adafruit_esp32spi.ESP_SPIcontrol(spi, esp32_cs, esp32_ready, esp32_reset)
"""Use below for Most Boards"""
status_light = neopixel.NeoPixel(
board.NEOPIXEL, 1, brightness=0.2
) # Uncomment for Most Boards
"""Uncomment below for ItsyBitsy M4"""

status_light = dotstar.DotStar(board.APA102_SCK, board.APA102_MOSI, 1, brightness=0.2)

Uncomment below for an externally defined RGB LED

import adafruit_rgbled

from adafruit_esp32spi import PWMOut

RED_LED = PWMOut.PWMOut(esp, 26)

GREEN_LED = PWMOut.PWMOut(esp, 27)

BLUE_LED = PWMOut.PWMOut(esp, 25)

status_light = adafruit_rgbled.RGBLED(RED_LED, BLUE_LED, GREEN_LED)

wifi = adafruit_esp32spi_wifimanager.ESPSPI_WiFiManager(esp, secrets, status_light)

Feeds

Setup a feed named 'photocell' for publishing to a feed

photocell_feed = secrets["aio_username"] + "/feeds/photocell"

photocell_feed = "/feeds/photocell"

Setup a feed named 'onoff' for subscribing to changes

#onoff_feed = secrets["aio_username"] + "/feeds/onoff"
onoff_feed = "/feeds/onoff"

Code

Define callback methods which are called when events occur

pylint: disable=unused-argument, redefined-outer-name

def connected(client, userdata, flags, rc):
# This function will be called when the client is connected
# successfully to the broker.
print("Connected to Adafruit IO! Listening for topic changes on %s" % onoff_feed)
# Subscribe to all changes on the onoff_feed.
client.subscribe(onoff_feed)

def disconnected(client, userdata, rc):
# This method is called when the client is disconnected
print("Disconnected from Adafruit IO!")

def message(client, topic, message):
# This method is called when a topic the client is subscribed to
# has a new message.
print("New message on topic {0}: {1}".format(topic, message))

Connect to WiFi

print("Connecting to WiFi...")
wifi.connect()
print("Connected!")

Initialize MQTT interface with the esp interface

MQTT.set_socket(socket, esp)

Set up a MiniMQTT Client

mqtt_client = MQTT.MQTT(
broker="io.adafruit.com",
username=secrets["aio_username"],
password=secrets["aio_key"],
)

Setup the callback methods above

mqtt_client.on_connect = connected
mqtt_client.on_disconnect = disconnected
mqtt_client.on_message = message

Connect the client to the MQTT broker.

print("Connecting to Adafruit IO...")
mqtt_client.connect()

photocell_val = 0
while True:
# Poll the message queue
mqtt_client.loop()

# Send a new message
print("Sending photocell value: %d..." % photocell_val)
mqtt_client.publish(photocell_feed, photocell_val)
print("Sent!")
photocell_val += 1
time.sleep(5)

Looks like the code was refactored into a subfolder which will change the imports currently being used in the examples:

Adafruit_CircuitPython_MiniMQTT/examples/minimqtt_simpletest.py

Line 9 in 4f01403

import adafruit_minimqtt as MQTT

and also guides?

Adafruit CircuitPython 5.3.0 on 2020-04-29; Adafruit PyPortal with samd51j20
>>> import adafruit_minimqtt as MQTT
>>> dir(MQTT)

@caternuson I'm going to update examples to import correctly and check against existing learn guides today.

Fixed in #41, released in 3.1.1.
