This document provides information about the AWS IoT Device SDK v2 for Python. If you have any issues or feature requests, please file an issue or pull request. This SDK is built on the AWS Common Runtime, a collection of libraries (aws-c-common, aws-c-io, aws-c-mqtt, aws-c-compression, aws-c-http, aws-c-cal, aws-c-auth, s2n ...) written in C to be cross-platform, high-performance, secure, and reliable. The libraries are bound to Python by the awscrt package (PyPI) (Github).

QUESTION
In a python application that uses the aws iot device sdk for python v2 (v1.7.1) I am running into an issue where I cannot update the device shadow.
After starting the program, the DeviceShadowManager will attempt to get the latest shadow state and set it locally.
If a delta state is present the DeviceShadowManager will merge the last reported state and delta state and publish it.
That works. However, when the manager subscribes for updates, after the initial setup, I am running into an error,
where when the desired state changes, the manager cannot update the reported state. Here is the error:

QUESTION
I'm setting up an AWS IoT MQTT connection from a Python environment using Python package awsiotsdk. I have followed this example https://github.com/aws/aws-iot-device-sdk-python-v2/blob/main/samples/pubsub.py and gotten the demo publish/subscribe to work, so I have all the pieces.
The only difference from the demo is that in my environment the certificates all reside in memory rather than on disk. A hack solution would be to write them to a temp location on disk and follow the example.
I would prefer to simply instantiate the appropriate AWS authentication class which can accept a file-like object rather than a string filename. However following the code only leads me to c-binding dead ends.
How can I create an MQTT client using in-memory certificates?
...ANSWER
Answered 2021-Jan-31 at 01:43As far as I've been able to determine, this is simply not possible. My solution is to use the tempfile package to create a temporary directory which I write the cert to and then reference when I create my MQTT client. It's not elegant, but it keeps me from needing to manage the certs as an external dependency (which is what I wanted to avoid).
QUESTION
I'm following the pubsub.py example code for AWS IoT using MQTT here. In particular I'm connecting to MQTT using the awsiotsdk.
That example works ok, but it connects to MQTT as a generic client, not as a specific device.
I would like to connect to MQTT to publish and subscribe as a specific device. In particular I want to be able to query for connected devices and see this device show up.
In the demo code I see that --client-id is included. By default it uses a UUID to generate a unique client ID for the demo. I've tried setting the client-id to the thing ARN arn:aws:iot:us-west-2:123456789012:thing/test
What I want/expect to see is the following search show the connected thing. The query comes back empty while the pubsub demo is running. The fact that it's empty tells me that the pubsub example is connecting as an MQTT client, not as a device. How do I connect as a device?
ANSWER
Answered 2021-Jan-26 at 00:07The clientId must equal the Thing name of a Thing registered in the Registry.
The connectivity status data is indexed only for connections where the client ID has a matching thing name.

ANSWER
Answered 2021-Jan-22 at 16:19For custom credentials file path set environment variables AWS_CONFIG_FILE and AWS_CREDENTIAL_FILE
For default profile set environment variable AWS_PROFILE with AWS profile name you would like to select as default. In order to use at runtime, this AWS profile name must be present in your AWS credentials file with valid configurations.
If you use only one AWS region, then you can also set environment variable AWS_DEFAULT_REGION. At times it saves few lines of code, where you might need to specify a AWS region.
