azure/azure-iot-sdk-python

A Python SDK for connecting devices to Microsoft Azure IoT services

azure-iot-device

The Azure IoT Device SDK for Python enables Python developers to easily create IoT device solutions that seamlessly connect to the Azure IoT Hub ecosystem.

• If you're looking for the azure-iot-hub library, it is now located in the azure-iot-hub-python repository

• If you're looking for the v1.x.x client library, it is now preserved in the v1-deprecated branch.

Installing the library

The Azure IoT Device library is available on PyPI:

pip install azure-iot-device

Python 3.7 or higher is required in order to use the library

Using the library

API documentation for this package is available via Microsoft Docs.

See our quickstart guide for step by step instructions for setting up and using an IoTHub with devices.

You can also view the samples repository to see additional examples of basic client usage.

Critical Upcoming Changes Notice

Certificates

All Azure IoT SDK users are advised to be aware of upcoming TLS certificate changes for Azure IoT Hub and Device Provisioning Service that will impact the SDK's ability to connect to these services. In October 2022, both services will migrate from the current Baltimore CyberTrust CA Root to the DigiCert Global G2 CA root. There will be a transition period beforehand where your IoT devices must have both the Baltimore and Digicert public certificates installed in their certificate store in order to prevent connectivity issues.

Devices with only the Baltimore public certificate installed will lose the ability to connect to Azure IoT hub and Device Provisioning Service in October 2022.

To prepare for this change, make sure your device's certificate store has both of these public certificates installed.

For a more in depth explanation as to why the IoT services are doing this, please see this article.

MQTT is not delivering the system properties: correlation_id and message_id

• OS and version used: Debian 8.9

• Python runtime used: Python 2.7.9

• SDK version used: 1.0.37

Description of the issue:

MQTT is not delivering the system properties: correlation_id and message_id
After correlation_id and message_id were set in IoTHubMessage, the reply message delivered to IoTHub does not contain correlation_id and message_id properties. Please, see the example below,

Code sample exhibiting the issue:

info_json = "{ 'channel' : 'httpResp', 'status' : 'HTTP/1.1 200 OK', 'headers' : { "'Server' : 'nginx/1.11.4', 'Content-type' : 'application/json', 'Transfer-Encoding' : 'chunked' , 'Connection' : 'keep-alive' }, 'body' : { 'data' } "

msg = IoTHubMessage(bytearray(info_json, 'utf8'))

Method 1

msg.correlation_id = 'value1'
msg.message_id = 'value2'

Method 2

msg_prop = msg.properties()
msg.pop.add('correlationId','value1')
msg.pop.add('messageId','value2')

client.send_event_async(msg, send_confirmation_callback, message_counter)

None of these methods work, the message sent does not contains the properties: correlation_id and message_id.

NOTE: For method 2, I used other possibilities of keys like: correlation_id, correlationId, CorrelationId, CorrelationIds

For our application is required and mandatory reply the correlation_id and message_id

Please, what can be done in order to fix this issue?

Console log of the issue:

No errors, the message is sent correctly, but, correlation_id and message_id are not delivered in the message

AMQP Support Document

Hi,

I didn't find any official document which demonstrates Azure IoT Hub AMQP support similar to MQTT Support Doc.

Can you please share the details of it.

AMQP transport failed to establish connection with service.

I have written a simple Python script with the following logic, summary it initiated the iothub_client once and loops forever. After some time, it seems to stop working, presumably when the authentication (using "iotHubClient = IoTHubClient(connection_string, protocol)" and the AMQP protocol) needs regenerate a SAS token.

Other than running "iotHubClient = iothub_client_init()", which seems inefficient, I suggest that the Python code not have to worry about it and the C code try to re-authenticate.

def main():
    global iotHubClient, UDP_IP, UDP_PORT

   
    try:
        sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        sock.bind((UDP_IP, UDP_PORT))

        iotHubClient = iothub_client_init()

        while True:
            data, addr = sock.recvfrom(1024) # buffer size is 1024 bytes
            data = data.replace('\r\n', '')
            try:
              UDPMessage = data.split(':')
              if UDPMessage[0] == "TempUpdate":
                message = '{ "event": "%s", "sensor": "%s", "temperature": %3.2f}' % (UDPMessage[0], UDPMessage[1], float(UDPMessage[2]))
                print message
                IoTmessage = IoTHubMessage(bytearray(str(message), 'utf8'))
                iotHubClient.send_event_async(IoTmessage, send_confirmation_callback, message)
            except:
              print data
            
    except IoTHubError as e:
        print("Unexpected error %s from IoTHub" % e)
        return
    except KeyboardInterrupt:
        print("IoTHubClient sample stopped")``

Build IoT SDK Python Samples failed in VS 2017

Hi,

I was trying to build python SDK on my windows 10 dev machine. I was not able to build the Python SDK samples even after i tried to upgrade the VS solutions to use VS 2017 latest build tools. when i execute a build using build.cmd i get the following error:

What are the packages need to be installed before running this script?

Please help me,

What are the packages need to be installed before running this script?

Because, when run the script I get this error,

ModuleNotFoundError Traceback (most recent call last)
in ()
11 from iothub_client import IoTHubClient, IoTHubClientError, IoTHubTransportProvider, IoTHubClientResult
12 from iothub_client import IoTHubMessage, IoTHubMessageDispositionResult, IoTHubError, DeviceMethodReturnValue
---> 13 from iothub_client_args import get_iothub_opt, OptionError

ModuleNotFoundError: No module named 'iothub_client_args'

I only have these packages at the moment

1. azure_iothub_device_client
2. azure_iothub_service_client

Thanks

I have tried a bunch of different things to make it work but I can't seem to get around this error. I am running Windows 10 (version 1703, build 15063.483) with Anaconda 4.3.14. I created an environment that contains the following packages:

> conda list
# packages in environment at C:\Users\sbran\Anaconda3\envs\azureiot:
#
azure-iothub-device-client 1.1.19.0                  <pip>

Here's the command I ran:

Note: The connection string above was just for a test device that I have deleted before posting this issue.

I both tried cloning the entire repository and running the sample from within the samples directory as well as downloading the three necessary files individually. Neither approach seems to work.

I am quite confused about the reference to the C:\Users\zolvarga\Documents directory printed in the output. This directory does not exist on my computer but it seems like it might on one of your developers' PCs (@zolvarga). How can this sort of reference sneak into production code? I don't understand that.

I hope you can help me debug this issue. Please let me know if you need any other diagnostics output from me.

Hi Guys,

After using both 2.7.13 and 3.6.1 and installing by python -m pip install azure-iothub-device-client and trying to run the sample, I get the following error message:

...Desktop\azure-iot-sdk-python\device\samples>python iothub_client_sample.py

    print ( "IoT Hub for Python SDK Version: %s" % iothub_client.__version__ )
AttributeError: 'module' object has no attribute '__version__'

It's the same message for both versions of Python.
Am I doing something fundamentally wrong?

Python HTTP Protocol Not Working for receiving messages.

From @asebak on December 3, 2016 22:45

When using AMQP the python library works fine for both sending and receiving messages. When using HTTP and configuring with a timeout and minimum polling period, messages are not received. I didn't set any certificates so not sure if that could be an issue from my side.

Copied from original issue: Azure/azure-iot-sdks#1011

Sample Program for Receiving C2D messages in Python

@schirag1993

We are working on it and the Python Service Client will be in the next release.
Also moving this issue to the Python repo: https://github.com/Azure/azure-iot-sdk-python

Thanks,

Unable to find remote helper for 'https'

Hi I've been following the instructions to run the python samples that connect with Azure IoT Hub using an Arduino YUN. When I execute this line:

git clone --recursive https://github.com/Azure/azure-iot-sdk-python.git

I always get this answer: "fatal: Unable to find remote helper for 'https' "

If I use "git" instead "https" it runs, but fails while it is cloning, this is the output taken from Putty:

Console log of the issue:

Mention somewhere in the doc the IoTHub Mgmt package

I generated and released the IoTHub Mgmt package from the Swagger file. I made a tiny quickstart here.

Should this doc/package mentioned somewhere in this repo?

Opposite question, do you want more than a reference here for your repo?

Unable to import client cert

Ubuntu 14.04
python 2.7
Master branch

I am unable to locate the following module which is referenced in the samples. I have built using the release.sh and installed into my venv

  from iothub_client_cert import CERTIFICATES

I can import the other modules, such as from iothub_client import IoTHubClient,

File missing

The file https://github.com/Azure/azure-iot-sdk-python/blob/doc/get_started/python-run-sample.md referenced in the device/readme.md is missing

General Question - Threading Model

Is there any documentation concerning the threading model used by this sdk?

In particular I'm curious how the callbacks are serviced? Is there a single IO thread which is handling these callbacks? I am assuming that is what drives the use of global variables in the examples?

Are issues we should be aware of with the threading model and the GIL?

Thanks!

Getting "No module named iothub_client" error

• Linux raspberrypi 4.4.50+ #970 Mon Feb 20 19:12:50 GMT 2017 armv6l GNU/Linux
• Python 2.7.9
• I don't see the SDK version anywhere. It is the current git code as of March 22, 2017

Description of the issue:

I followed these unix instructions (defaulted to python 2.7) to compile the SDK on my Pi: https://github.com/Azure/azure-iot-sdk-python/blob/master/doc/python-devbox-setup.md. When complete, I tried the sample:

python iothub_client_sample.py -c HostName=myhub.azure-devices.net;DeviceId=RaspberryPiZero;SharedAccessKey=MyKey -p amqp

I got an "ImportError: No module named iothub_client" error

I recompiled and see that I am getting an error with the compilation. I have attached the build log.

azure_iothub_device_client for Raspbian Jessie is not found

Hi,

I was trying to run "iot_hub_client_sample.py" sample app from my Pi Zero. It seems that there is no build for Raspbian Jessie for his package. Is there any workaround for this?

I want to be able to run python apps that integrates with IoT Hub from my Pi Zero W device. Any direction is appreciate it.

Thanks.

Error when building Python SDK on RPi 2 (Raspbian)

Hi,
I'm trying to connect my Raspberry Pi 2 (running Raspbian Wheezy) to my MS IoT hub. Process:

1. I first fetched the Python SDK to the Pie with:

git clone --recursive https://github.com/Azure/azure-iot-sdk-python.git

The installed Python version is 2.7.3.

2. Then I ran through the setup of the Python SDK successfully (including a cmake-3.2.2 update).

3. Moved on to compiling the Python SDK by following this guide: https://github.com/Azure/azure-iot-sdk-python/blob/master/doc/python-devbox-setup.md#linux

Problem: The build gets stuck at 97% (see error printout below). The guide I linked to above actually describes that the build could get stuck at 98% (when building Python client library iothub_client.so) due to lack of memory. I checked this and yes, I had memory issues, so I increased the swapfile size to 1 GB as suggested in the guide. This increase of memory gives me some 100MB memory margin, but I still get the exact same error message at 97% (see the printout below).

Any tips or suggestions on how to get this resolved?

Error printout:
pi@raspberrypi ~/azure-iot-sdk-python/build_all/linux $ sudo ./build.sh ... ...

Error in sample from Windows

• OS and version used: Windows 10

• Python runtime used: Python 3.4.3

• SDK version used: azure-iothub-device-client 1.1.16.0

Description of the issue:

I installed successfully through pip the azure-iothub-device-client (1.1.16.0) but when I try to import iothub_client (as in the samples given in the project) I get the error below.

Code sample exhibiting the issue:

import iothub_client

Compiled from git clone --recursive https://github.com/Azure/azure-iot-sdk-python.git
Copied iothub_client.so from device samples folder to my own folder.
Tests all say OK when it built

Code:

self.iotClient = IoTHubClient(connString, IoTHubTransportProvider.AMQP_WS)
self.iotClient.set_option("messageTimeout", "5")

Console log of the issue:

It looks like maybe there could be something left over from compiling or setting up, I did try a fresh git clone into a different folder and the issue persists.
I ran both setup.sh and build.sh.
Any step to clear this out?

PLAT_ARCH in linux release not working

UBUNTU 14.04
PYTHON 2.7

In release.sh I was forced to change to PLAT_ARCH which is passed to --plat-name

Is this expected or an issue with my environment?

if [[ "$(uname -m)" = "x86_64" ]] ; then
    PLAT_ARCH="linux_x86_64"
else
    PLAT_ARCH="linux32"

If I do not make the change I receive ... is not a supported wheel on this platform.

Timeout not working as expected with MQTT

Ubuntu 14.04
Master Branch
Python 2.7.6

Protocol: MQTT

Timeouts are taking longer than I expect, in the example below my expectation is 5 seconds for timeout. I believe I am setting the timeout setting properly.

I am testing this by allowing the code to proceed all the way to the first print statement, where I have a breakpoint. I then disconnect my eth0 and wait for the timeout.

Code Snippet

        self.client.set_option("messageTimeout", 5)

        .....

        print time.time()
        self.client.send_event_async(event, send_confirmation_callback, 1)
        
        while WAITING_ON_RESPONSE:
            time.sleep(.250)

        print CONFIRMATION_RESULT
        if CONFIRMATION_RESULT == IoTHubClientConfirmationResult.MESSAGE_TIMEOUT:
            print "timeout"
            print time.time()

Looking for Python sample code to get device historical messages from iothub

Hi,

I am working on a task to get historical D2C device messages from iothub with Python language. I wasn't able to find any helpful example code from internet. Can someone provide me some example code?

Closed issue Azure/azure-sdk-for-python#1131.

Thank you very much in advance!

Problem importing iothub_client in Windows

Hi,

I have just installed Python 3.6.0 in a Windows 10 machine.
I have then installed the iothub-client package using the command: pip install iothub-client
The installation completed successfully. However, when I try importing the package I get the following error:

import iothub_client
Traceback (most recent call last):
File "", line 1, in
File "C:\Python36-32\lib\site-packages\iothub_client_init_.py", line 1, in
from .iothub_client import *
ImportError: DLL load failed: The specified module could not be found.

Any help is much appreciated.
Thanks,
Pedro

• OS and version used: Any

• Python runtime used: 2.7

• SDK version used: IoT Hub SDK for C, version 1.1.12

Description of the issue:

Build error when disabling AMQP and service client support. An example scenario where disabling those might be wanted is when building on a Raspberry Pi and just wanting to use the device client with MQTT.

Code sample exhibiting the issue:

Example cmake flags that trigger the issue:

Console log of the issue:

The issue is two-fold.

The first error is:

Grouping device-to-cloud messages into batches

The documentation says batching is possible for up to 256KB (https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-devguide-messaging). However, I can't find the right endpoint in the preliminary API nor in the REST documentation. The C# API has implemented such a call. Am I missing something?

AMQP SASL Documentation

Hello, I've seen the other issue related to documentation. This is a similar request.

Following https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-devguide-security

Is it required to encode the SAS token when using SASL-Plain?

I'll note I have looked at https://github.com/Azure/azure-iot-sdk-python/tree/master/device/samples but did not see any usage of sas tokens only the policy keys.

Python IoTHub package should be under Microsoft banner

Hello,

The IoTHub package should be also owned by the Microsoft account. We are "One microsoft", and this helps people to have confidence and allows them to find all Microsoft packages in one page.

Account is managed by @zooba and @brettcannon , we do not claim ownership or something, it's just a way to group packages unto the Microsoft banner.
