allthingtalk socket

[almeos]

Hello,
Does someone has ever tried to connect a fipy to 'orange.allthingstalk.com', because I do not manage to connect a socket, it allways shows the error "[Errno 113] ECONNABORTED"
I have a fipy + expansion board with a orange SIM card.

>>> lte.connect()
>>> lte.isconnected()
True
>>> address = socket.getaddrinfo('api.allthingstalk.io',8891)
>>> print(address)
[(2, 1, 0, '', ('40.68.172.187', 8891))]
>>> s = socket.socket()
>>> s = ssl.wrap_socket(s)
>>> s.connect(address[0][-1])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: [Errno 113] ECONNABORTED
>>> 

On the other hand, I manage to connect socket to 'google':

>>> lte.connect()
>>> lte.isconnected()
True
>>> address = socket.getaddrinfo('www.google.com', 443)
>>> print(address)
[(2, 1, 0, '', ('172.217.17.36', 443))]
>>> s = socket.socket()
>>> s = ssl.wrap_socket(s)
>>> s.connect(address[0][-1])
>>> 

It would be great if I had a solution. Thank you in advance

One minor addition I wanted to make.. If AllThingsTalk uses the MQTT protocol, you should not use the HTTP request I was suggesting, but switch to the MQTTClient library from micropython

@Gijs Thank you for your investment. I am going to work with your answer and will inform you as soon as I have a result.
Best regards

Hi
Sorry, my experience is limited with allthingstalk. I believe you should connect to port 80, and then send a HTTP request (GET / POST depending on your settings)
I found this online: https://docs.allthingstalk.com/developers/api/get-started/first-device/
It seems you have to attach the autorization in the headers, and implement your JSON data where i mention data.

When searching, I also found a Python library for allthingstalk, maybe that is compatible with micropython, but Im not sure.. That might make things easier.

In this example, I manually construct the HTTP header and data, such that it will be received properly by AllThingsTalk: (Sorry I did not test this for mistakes in the HTTP, it is merely what it should look like)

import socket

s = socket.socket()
address = socket.getaddrinfo('api.allthingstalk.io',80)[0][-1]

s.connect(address)

s.send(b'GET /device/token HTTP/1.0\r\n\r\n Authorization: Bearer maker:token \r\n "Content-Type: application/json" data'

@Gijs Thank you for your answer.
It seems to connect with port 80.

>>> s = socket.socket()
>>> address = socket.getaddrinfo('40.68.172.187',80)
>>> print(address)
[(2, 1, 0, '', ('40.68.172.187', 80))]
>>> s.connect(address[0][-1])
>>> s.send(b'R5VBDxxxxxxxxrmROhNnpSgD\nmaker:4SRXQxxxxxxxx1VeVtzN6xSghrrwi5pzkpqgTQq\n{"Test01":{"value":1}}')
93
>>> 

I do not have any response on "https://orange.allthingstalk.com/"

Do I use the right format of micro python command to send the value of Test01?

Hi,

I get this as well for api.allthingstalk.io on port 8891, but it does not happen on port 80. I believe the connection is being refused as the port is not open?
