The Eclipse Foundation announced new releases of two open-source Internet of things (IoT) projects based on the OASIS Message Queue Telemetry Transport or MQTT standard protocol.
Eclipse announced the release of Eclipse Paho 1.1 and Eclipse Mosquitto 1.4, which both implement the client and broker for the OASIS MQTT standard.
Both project releases continue the momentum enjoyed by the Eclipse IoT open-source community and the adoption of the MQTT standard by IoT solution providers, said Ian Skerrett, vice president of marketing for the Eclipse Foundation.
Eclipse IoT is an open-source community focused on building open-source technology for IoT developers, Skerrett said. The community has 15 different open-source projects that implement popular IoT standards, such as MQTT, Lightweight M2M, and CoAP, and IoT frameworks that developers can use to accelerate development of IoT solutions.
MQTT is a popular IoT messaging protocol that has been adopted by several IoT solution providers. It is a lightweight publish/subscribe messaging transport that is well-suited for connecting small devices to the Internet. It requires a small footprint on the client and minimal bandwidth for the messages, and adapts well to unreliable network connections. MQTT 3.1.1 was ratified as an OASIS standard in November.
“In the last year, we have seen tremendous interest in the Eclipse IoT community, and in particular Paho and Mosquitto,” Mike Milinkovich, executive director of the Eclipse Foundation, said in a statement. “Forty developers contributed to the new Paho and Mosquitto releases, demonstrating incredible interest for these projects and MQTT in general.”
The Eclipse Foundation said the Paho project provides open-source client implementations of open and standard messaging protocols aimed at new, existing and emerging applications for machine‑to‑machine (M2M) and IoT.
Paho 1.1 implements the MQTT client specification. New to the 1.1 release are support for Microsoft .NET, WinRT and Android clients; C and C++ libraries for embedded clients; and updated versions of the Java, Python, and JavaScript clients to conform to the MQTT 3.1.1 standard. Paho 1.1 is available for download here.
Mosquitto provides a lightweight server implementation of the MQTT and MQTT-SN protocols, written in C. Mosquitto 1.4 implements the MQTT broker specification. New to the 1.4 release are easier integration with Websites via support for WebSockets; improved security by providing more flexible support for TLS v1.2, 1.1 and 1.0 plus support for ECDHE-ECDSA family ciphers; and better interoperability between MQTT brokers via improved bridge support, including wildcard Transport Layer Security (TLS) certificates and conformance to MQTT 3.1.1. Mosquitto 1.4 is available for download here.
Paho and Mosquitto are being used by companies and enterprises to add support for MQTT in IoT solutions. The projects’ open-source licenses allows for royalty-free use of the technology.
For example, Bluewind is using Mosquitto and Paho MQTT tools and libraries to build a new coffee machine for Illy. Dc-square GmbH is using Eclipse Paho as the client library of choice of most of its HiveMQ MQTT broker customers. Logi.cals GmbH is using MQTT to connect different target systems of its Soft-PLC runtime system, also known as logi.RTS. Eclipse Paho and the Mosquitto MQTT-broker enabled it to jump-start the development of products for both the IoT world as well as for the industrial sector. And SSV Software Systems GmbH uses the Eclipse Paho libraries and the Eclipse MQTT broker Mosquitto to provide a highly secured IoT platform.
