Connect Python, Javascript and Micropython based devices to Arduino Cloud

Development Tools Cloud IoT
1

Hi!

We are really excited to announce that now it is possible to connect seamlessly to the IoT Cloud devices that use Python, Micropython and Javascript. This can be done using the new "Manual Setup Device" workflow that can be triggered when Adding a new Device.

You can read the full story here or check the article in the documentation to learn how to get started.

Your feedback is highly appreciated, so please, share with us your projects, improvement ideas, etc.

This looks to be a great upgrade, but I'm having trouble getting it going. In the first instance I thought I'd give this a test drive with my Windows laptop running Python 3.11.4. I tried to load the Python package using the suggested "pip install arduino-iot-cloud-py" but got the error message below. Any ideas as to what the problem might be?

ERROR: Could not find a version that satisfies the requirement arduino-iot-cloud-py (from versions: none)
ERROR: No matching distribution found for arduino-iot-cloud-py

Hi @robertics. It looks like there is an error in the documentation. The package name is arduino_iot_cloud, not arduino-iot-cloud-py. So you should use this command:

pip install arduino_iot_cloud
5

That got me a lot closer, but I think there is a dependency issue. Simply running

pip install arduino_iot_cloud

Raises an error:

So I then ran pip install swig which tried to load, but also failed indicating that it can't find swig.

@robertics, I tried the same but then downloaded swig and manually added it to the path on my Windows machine. I downloaded the zip from Download swigwin-4.1.1.zip (SWIG).
That got a little further once I did but then it failed on

      Deprecated command line option: -modern. Ignored, this option is now always on.

which is possibly to do with -I/usr/include/openssl.
I tried changing to to "-Ic:\program files\openssl-win64\include" but got
c:\Program Files\Openssl-Win64\include\openssl\e_os2.h(255) : Error: Unable to find 'stdint.h'

@dbraken, you did better than me. I think this all points to a wider installation issue that will need to be sorted out by the developers.

I had another go on a Raspberry Pi 4B running Python 3.9.2 and the example worked.

I did take the precaution of loading the swig module before doing anything else. That loaded without issue. I then loaded the arduino-iot-cloud module.

To be clear I ran the following:

pip install swig
pip install arduino-iot-cloud

I tried the above on a different Raspberry Pi 4B running Python 3.8.0 and a Raspberry Pi Zero 2 W running Python 3.9.2. They both worked.

I returned to the Windows laptop with swig added to the path as suggested by @dbracken, but that still failed at the same point as before. I tried it in a Windows PowerShell and also in a virtual environment in VSCode. I beleave in both cases swig is installed and on the search paths because the full help message is returned in response to entering "swig -help" at the command lines. But in both cases the pip install arduino_iot_cloud results in an error message saying "ModuleNotFoundError: No module named 'swig'".

I have now submitted a fix for the error:

Thanks Arduino Team, that will address the typo that we are all aware of (thanks to your much earlier comment) but it does not address M2Crypto not being able to find the OpenSSL source files (which I have in C:\usr\include\openssl)

After seeing your post above, I started again with a fresh installation of Python 3.11.4 on windows 10, pip install wheel, installed swig and put it in the path, downloaded OpenSSL and have it in the location above but I cannot install arduino-iot-cloud. What am I missing? If somebody has installed this on Windows 10/11, please let us know how your process differs.

I agree that this must be addressed if the tutorial is to be of any use for many of those who it is intended to serve.

Even though my level of technical expertise is significantly higher than what should be considered the prerequisite for following such a tutorial, I was unable to find any reasonable way to install all the dependencies on my Windows machine.

@dbeamonte_arduino would you mind following up on this and help the content team to make the tutorial and/or Python package into something the target user has any hope of using on Windows?

I just tried to install swig then arduino-iot-cloud to the global installation of Python 3.11.4 (i.e. not a virtual env) on a Windows 11 laptop. I got the same net result as @dbracken.


PS C:\Users\account\Documents> pip install arduino-iot-cloud

Hi all! Pip needs a little help to get the dependencies installed. Here's how I got to install it on macOS:

  • pip install swig
  • brew install openssl
  • pip install --global-option=build_ext --global-option="-I/usr/local/opt/openssl/include" m2crypto
  • pip install arduino-iot-cloud

On Windows something like this should work:

  • pip install swig
  • choco install openssl
  • pip install --global-option=build_ext --global-option="-IC:\Program Files\OpenSSL-Win64\include" m2crypto
  • pip install arduino-iot-cloud

If that doesn't work, please take a look here: INSTALL.rst · master · m2crypto / m2crypto · GitLab

Thnx, I followed your macOS steps above and I'm also/still getting an error claiming that the swig module cannot be found. But it's there, see attached screen shot. Any suggestions?

Hello everyone!

The arduino-iot-cloud package has been updated recently. Previously, the M2Crypto package was needed for authentication, but you can now use basic authentication (Device ID & Secret Key that is obtained during device config).

To use it, the swig package also needs to be installed (using pip install swig). Installation of has been tested on both Mac & Windows and is now working. Hopefully this will resolve the issues that you guys are having.

I have made some small modifications to the documentation, such as adding the swig installation instructions. Also, thank you @ptillisch for updating the incorrect installation instructions.

Note: you may need to delete/uninstall the arduino-iot-cloud package and re-install it, this was the case for me.

That's a solution for Windows 11 running Python 3.11.5 - confirmed.

Happy it worked @robertics, please feel free to share the results of your project at any time, I'd be interested to see how it worked out :slight_smile:
