This advanced, industrial-grade TCP/IP network stack is designed specifically for deeply embedded real-time and IoT applications. Azure RTOS NetX Duo is a dual IPv4 and IPv6 network stack, while Azure RTOS NetX is the original IPv4 network stack, essentially a subset of Azure RTOS NetX Duo.

Documentation for this library can be found here: http://docs.microsoft.com/azure/rtos/netx-duo

The master branch has the most recent code with all new features and bug fixes. It does not represent the latest General Availability (GA) release of the library.

Each official release (preview or GA) will be tagged to mark the commit and push it into the Github releases tab, e.g. v6.1-rel.

NetX Duo has a couple of dependencies that are included as submodules. To clone the repo:

$ git clone https://github.com/azure-rtos/netxduo.git
$ git submodule update --init

NetX Duo includes Azure IoT Middleware for Azure RTOS (a.k.a IoT Middleware), a platform specific library that acts as a binding layer between the Azure RTOS and the Azure SDK for Embedded C.

The IoT Middleware also includes Azure services integrations for:

The Device Update for IoT Hub ^{Public Preview} is an Azure services for IoT solution to enable the over-the-air (OTA) easily. The IoT Middleware provides the module with simple APIs for device builder easily adding the OTA feature. Additional APIs, docs and sample projects can be found on the feature/adu branch.

The Azure Defender for IoT security module provides a comprehensive security solution for Azure RTOS devices. Azure RTOS now ships with the Defender for IoT security module built-in and provides coverage for common threats and potential malicious activities. The security module is part of the Azure IoT Middleware for Azure RTOS (addons/azure_iot/). As the device connects to Azure IoT hub, Defender for IoT collectors gather network connectivity information and sends it to the Defender for IoT service for analysis. For details on how the security module works and the type of information it collects, refer to Azure Defender for IoT security module section in the Azure IoT document.

Azure RTOS provides OEMs with components to secure communication and to create code and data isolation using underlying MCU/MPU hardware protection mechanisms. It is ultimately the responsibility of the device builder to ensure the device fully meets the evolving security requirements associated with its specific use case.
