Paho

Paho is a software library that provides a set of APIs for working with MQTT (Message Queuing Telemetry Transport) messaging protocol. MQTT is a lightweight, publish-subscribe network protocol that is designed for constrained devices and low-bandwidth, high-latency, or unreliable networks. Paho is developed by the Eclipse Foundation and is available under the Eclipse Public License.

The Paho library is written in C and is designed to be portable and efficient. It is used in a variety of applications, including IoT (Internet of Things) devices, mobile applications, and web applications. The library provides a simple API for publishing and subscribing to messages, as well as for managing connections to MQTT brokers.

Paho is available in several programming languages, including C, Java, Python, and JavaScript. Each language-specific implementation provides a consistent API, making it easy to switch between languages without changing the underlying code. The library is also designed to be easy to use, with a focus on simplicity and ease of integration.

Paho is widely used in the industry and is supported by a large community of developers. The library is regularly updated and maintained, with new features and bug fixes released on a regular basis. The Eclipse Foundation provides documentation, tutorials, and examples to help developers get started with Paho and MQTT.
