AWS IoT SDK based on the AWS Common Runtime

AWS IoT Device SDK for Python v2

The AWS IoT Device SDK for Python v2 connects your Python applications and devices to the AWS IoT platform. It handles the complexities of secure communication, authentication, and device management so you can focus on your IoT solution. The SDK makes it easy to use AWS IoT services like Device Shadows, Jobs, and Fleet Provisioning.

Supported Platforms: Linux, Windows 11+, macOS 14+

Note: The SDK is known to work on older platform versions, but we only guarantee compatibility for the platforms listed above.

Features

The primary purpose of the AWS IoT Device SDK for Python v2 is to simplify the process of connecting devices to AWS IoT Core and interacting with AWS IoT services on various platforms. The SDK provides:

• Integrated service clients for AWS IoT Core services
• Secure device connections to AWS IoT Core using MQTT protocol including MQTT 5.0
• Support for multiple authentication methods and connection types
• Support for manual publish acknowledgement for control over QoS 1 PUBACK delivery

Supported AWS IoT Core services

• The AWS IoT Device Shadow service manages device state information in the cloud.
• The AWS IoT Jobs service sends remote operations to connected devices.
• The AWS IoT fleet provisioning service generates and delivers device certificates automatically.

Installation

The recommended way to use the AWS IoT Device SDK for Python v2 in your project is to install it from PyPI.

Minimum Requirements

To develop applications with the AWS IoT Device SDK for Python v2, you need:

• Python 3.8+

See detailed setup instructions for more information.

Installing from PyPI

macOS and Linux:

python3 -m pip install awsiotsdk

Windows:

python -m pip install awsiotsdk

Building from source

See the Development Guide for detailed instructions on building from source and using local builds.

Getting Started

To get started with the AWS IoT Device SDK for Python v2:

1. Install the SDK - See the Installation section for installation details

2. Choose your connection method - The SDK supports multiple authentication methods including X.509 certificates, AWS credentials, and custom authentication. MQTT5 User Guide connection section and MQTT5 X509 sample provide more guidance

3. Follow a complete example - Check out the samples directory

4. Learn MQTT5 features - For advanced usage and configuration options, see the MQTT5 User Guide

Samples

Check out the samples directory for working code examples that demonstrate:

• Basic MQTT connection and messaging
• AWS IoT Device Shadow operations
• AWS IoT Jobs
• AWS IoT Fleet provisioning: basic and with CSR

The samples provide ready-to-run code with detailed setup instructions for each authentication method and use case.

Specifics

Mac-Only TLS 1.3

By default, macOS uses Apple Secure Transport as the TLS implementation, which supports up to TLS 1.2. To enable TLS 1.3 on macOS, set the environment variable AWS_CRT_USE_NON_FIPS_TLS_13=1 before running your application. This switches the TLS backend to s2n-tls with aws-lc at runtime.

[!IMPORTANT] Enabling AWS_CRT_USE_NON_FIPS_TLS_13 trades FIPS compliance and macOS Keychain/PKCS#12 integration for TLS 1.3 support. This variable has no effect on Linux or Windows.

Mac Keychain

When using the default Apple Secure Transport backend, once a private key is used with a certificate, that certificate-key pair is imported into the Mac Keychain. All subsequent uses of that certificate will use the stored private key and ignore anything passed in programmatically. When a stored private key from the Keychain is used, the following will be logged at the "info" log level:

static: certificate has an existing certificate-key pair that was previously imported into the Keychain.
 Using key from Keychain instead of the one provided.

Getting Help
