...The project is designed for IoT, machine-to-machine messaging, telemetry, home automation, embedded devices, and distributed systems that need efficient event delivery. It includes the broker itself, C and C++ client libraries, and command-line tools for publishing, subscribing, request-response testing, password management, broker control, and signaling. Mosquitto is portable and can run on small devices, servers, containers, and many operating systems. Its main value is providing a mature, lightweight, widely adopted MQTT implementation for reliable messaging in constrained and production environments.

...For example, you can define a new metric to monitor the memory usage or CPU usage on your devices. This library has no dependencies on any additional libraries other than the standard C library, and therefore, can be used with any MQTT client library. This library is distributed under the MIT Open Source License. This library has gone through code quality checks including verification that no function has a GNU Complexity score over 8, and checks against deviations from mandatory rules in the MISRA coding standard. Deviations from the MISRA C:2012 guidelines are documented under MISRA Deviations. ...

The AWS IoT Device SDK for Embedded C (C-SDK) is a collection of C source files under the MIT open source license that can be used in embedded applications to securely connect IoT devices to AWS IoT Core. It contains MQTT client, HTTP client, JSON Parser, AWS IoT Device Shadow, AWS IoT Jobs, and AWS IoT Device Defender libraries. This SDK is distributed in source form and can be built into customer firmware along with application code, other libraries, and an operating system (OS) of your choice. These libraries are only dependent on standard C libraries, so they can be ported to various OS's - from embedded Real-Time Operating Systems (RTOS) to Linux/Mac/Windows. ...

The Fleet Provisioning library enables you to provision IoT devices without device certificates using the Fleet Provisioning feature of AWS IoT Core. For an overview of provisioning options available, see Device provisioning. This library has no dependencies on any additional libraries other than the standard C library, and therefore, can be used with any MQTT library. This library is distributed under the MIT Open Source License. This library has gone through code quality checks including...

The AWS IoT Jobs library helps you notify connected IoT devices of a pending Job. A Job can be used to manage your fleet of devices, update firmware and security certificates on your devices, or perform administrative tasks such as restarting devices and performing diagnostics. It interacts with the AWS IoT Jobs service using MQTT, a lightweight publish-subscribe protocol. This library provides a convenience API to compose and recognize the MQTT topic strings used by the Jobs service. The...

The AWS IoT Device Shadow library enables you to store and retrieve the current state (the “shadow”) of every registered device. The device’s shadow is a persistent, virtual representation of your device that you can interact with from AWS IoT Core even if the device is offline. The device state is captured as its “shadow” within a JSON document. The device can send commands over MQTT to get, update and delete its latest state as well as receive notifications over MQTT about changes in its...

OWLOS Open source network operating system for managing IoT devices: - does't require internet access or additional servers - ready to connect sensors, actuators, LCD, DHT, Stepper and other devices - does't require programming skills - built-in user interface - use web browser to access and manage your OWLOS nodes - built-in RESTful server - built-in MQTT client - at the same time WiFi access point and station, in any combination: - can be used autonomously - can work on a local network can work via the Internet can integrate with other nodes running under OWLOS - organizing an internal network. without using a servers available in source code
