AWS IoT Device Support for LoPy

[jomifo]

Hi @daniel, I am also having issues with your aws demo.

When I break out of the loop and test the connection manually I get OSError -32512

DEVICE_ID = "lopy-gateway"
HOST = "[redacted].iot.us-east-2.amazonaws.com"
TOPIC_DOWNLOAD = "Download"
TOPIC_UPLOAD = "Upload"
from simple import MQTTClient
connection = MQTTClient(DEVICE_ID, server=HOST, port=8883)
connection.connect(ssl=True, certfile='/flash/cert/lopy-gateway.cert.pem', keyfile='/flash/cert/lopy-gateway.private.key', ca_certs='/flash/cert/root-CA.crt')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "simple.py", line 77, in connect
OSError: -32512

I have tested from my desktop using the Python AWSIoTPythonSDK module from AWS with the same credentials successfully.

I could send my code if that would help.

Thanks for any insight.

@daniel Could you please confirm your AWS IoT demo still works for you?
I am using the latest firmware and when trying to connect to the MQTT broker using the REPL, I get OSError 0-

>>> connection.connect(ssl=True, certfile='/flash/cert/lopy-gateway.cert.pem', keyfile='/flash/cert/lopy-gateway.private.key', ca_certs='/flash/cert/root-CA.crt')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "simple.py", line 79, in connect
OSError: 0
>>>                                          
>>> 
>>> import os
>>> os.uname()
(sysname='LoPy', nodename='LoPy', release='1.0.1.b1', version='v1.8.6-265-g5722083 on 2016-12-22', machine='LoPy with ESP32')

@jomifo I'll be performing some tests this morning and get I'll get back with an update shortly.

Cheers,
Daniel

@jomifo I can confirm that the issue is there, we also get the exception with OSError 0. We'll investigate it and provide and solution on tomorrow's release.

@daniel - I tried this in the latest release (1.1.0.b1) and am now getting a different OSError. Just wondering if you were able to address this in the latest release and verify your AWS IoT demo works so I know if it is something on my end. Thanks.

@jomifo we are also experiencing that error and it is caused by the changes made to integrate the Bluetooth stack. We are still investigating the exact root cause. Apologies for the the delay.

[jomifo]

@daniel No problem. Thanks for the quick confirmation reply.

@gertjanvanhethof no, we are still busy trying to solve it. It's going to have to wait for the next release.

Hello Daniel, dear all,

I used your code and could do interaction with a custom mosquitto MQTT broker + Let's encrypt certificate (so using TLS on port 8883 and server authentication) from my WiPy. Still using the older firmware from Dec 16th which works fine with TLS + certificates.

Many thanks for the great work!

@daniel Just checking... this is still an open issue, correct? Thanks.

@daniel also interested in a working sample code.

@jomifo I have made a mini guide for this issue: https://forum.pycom.io/topic/908/umqtt-aws-iot
