sample minimqtt_simpltest.py MQTT connect error

[gddeen]

I run minimqtt_simpletest.py and get connect issues.

Error observed:
code.py output:
Connecting to AstroACN3

I'm running 6.2beta
cat boot_out.txt
Adafruit CircuitPython 6.2.0-beta.3 on 2021-03-04; Adafruit MagTag with ESP32S2

======================================================

The board has an e-ink 4.2" display hooked up at EDP_SPI, I5, 6, 7, 8

The user, me, has a single feed temperature with a value of 27

I'm available 24 hours a day...

    log=True
)

Traceback (most recent call last):
File "code.py", line 51, in
TypeError: unexpected keyword argument 'log'

[gddeen]

The boot_out.txt reads MagTag not Metro. Could this board think it is a Magtag?

[bangell]

I believe this issue was fixed today in version 5.0.5

[gddeen]

Today I got the Metro ESP32-S2 to confirm it wasn't a Magtag by loading adafruit-circuitpython-adafruit_metro_esp32s2-en_US-6.2.0-beta.4.uf2 and replacing lib directories and mpy files.

I rerun and get:

Attempting to connect to io.adafruit.com

TypeError: can't convert str to int

[ghayne]

In secrets.py
Instead of

'port' : "8883"

Try

'port' : 8883

[gddeen]

I reloaded some of my client code to connect to MQTT.
Once I perform io.connect() it gets an exception.

Is there a more directed way to debug this?
I am going to take all the bundle lib source for adafruit_io and adafruit_minimqtt
and put that in my library and liberally spread print() so I can follow the execution path.

I had in secrets:
"aio_port" : "8883"
instead of
"aio_port" : 8883

Fixed

[gddeen]

Thanks for all the help everyone.

[brentru]

Aha! We should really validate if port is an integer within this lib's init call.

I'll leave this issue open and assign myself so I can make a small tweak.
