This repository contains code for the Azure IoT SDKs for Python. This enables python developers to easily create IoT device solutions that seamlessly connect to the Azure IoT Hub ecosystem.
If you're looking for the v1.x.x client library, it is now preserved in the v1-deprecated branch.
This repository contains the following libraries:

Coming Soon: Azure IoT Device Provisioning Service Library
Pip installs are provided for all of the SDK libraries in this repo:

Device Client Library (azure-iot-device)
| Features | Status | Description |
|---|---|---|
| Authentication | ✔️ | Connect your device to IoT Hub securely with supported authentication, including symmetric key, X-509 Self Signed, and Certificate Authority (CA) Signed. SASToken authentication is not currently supported. |
| Send device-to-cloud message | ✔️ | Send device-to-cloud messages (max 256KB) to IoT Hub with the option to add custom properties. |
| Receive cloud-to-device messages | ✔️ | Receive cloud-to-device messages and read associated custom and system properties from IoT Hub, with the option to complete/reject/abandon C2D messages. |
| Device Twins | ✔️ | IoT Hub persists a device twin for each device that you connect to IoT Hub. The device can perform operations like get twin tags, subscribe to desired properties. |
| Direct Methods | ✔️ | IoT Hub gives you the ability to invoke direct methods on devices from the cloud. The SDK supports handler for method specific and generic operation. |
| Connection Status and Error reporting | ✖️ | Error reporting for IoT Hub supported error code. *This SDK supports error reporting on authentication and Device Not Found. |
| Retry policies | ✖️ | Operations which fail with a transient error and dropped connections will be retried with a fixed 10 second interval. There is currently no way to change this behavior. |
| Upload file to Blob | ✔️ | A device can initiate a file upload and notifies IoT Hub when the upload is complete. |
Note: IoT Edge for Python is scoped to Linux containers & devices only. Learn more about using Linux containers for IoT edge on Windows devices.

| TPM Individual Enrollment | ➖ | Provisioning via Trusted Platform Module. |
| X.509 Individual Enrollment | ✔️ | Provisioning via X.509 root certificate. Please review the samples folder and this quickstart on how to create a device client. |
| X.509 Enrollment Group | ✔️ | Provisioning via X.509 leaf certificate). Please review the samples folder on how to create a device client. |
| Symmetric Key Enrollment | ✔️ | Provisioning via Symmetric key attestation). Please review the samples folder on how to create a device client. |
IoTHub Service Library (azure-iot-hub)
| Features | Status | Description |
|---|---|---|
| Identity registry (CRUD) | ✔️ | Use your backend app to perform CRUD operation for individual device or in bulk. |
| Cloud-to-device messaging | ✔️ | Use your backend app to send cloud-to-device messages, and set up cloud-to-device message receivers. |
| Direct Methods operations | ✔️ | Use your backend app to invoke direct method on device. |
| Device Twins operations | ✔️ | Use your backend app to perform device twin operations. *Twin reported property update callback and replace twin are in progress. |
| Query | ✔️ | Use your backend app to perform query for information. |
| Jobs | ✖️ | Use your backend app to perform job operation. |
Feature is Coming Soon
| Features | Status | Description |
|---|---|---|
| CRUD Operation with TPM Individual Enrollment | ✖️ | Manage device enrollment using TPM with the service SDK. |
| Bulk CRUD Operation with TPM Individual Enrollment | ✖️ | Bulk manage device enrollment using TPM with the service SDK. |
| CRUD Operation with X.509 Individual Enrollment | ✖️ | Manages device enrollment using X.509 individual enrollment with the service SDK. |
