8. ICU4C – Unicode Library

The C and C++ languages and many operating system environments do not provide full support for Unicode and standards-compliant text handling services. Even though some platforms do provide good Unicode text handling services, portable application code can not make use of them. The ICU4C libraries fills in this gap. ICU4C provides an open, flexible, portable foundation for applications to use for their software globalization requirements. ICU4C closely tracks industry standards, including Unicode and CLDR (Common Locale Data Repository). The ICU license is intended to allow ICU to be included both in free software projects and in proprietary or commercial products. Since ICU 58, ICU is covered by the Unicode license which is very similar to the previous ICU license.

9 JSMN – JSON parser in C

jsmn (pronounced like 'jasmine') is a minimalistic JSON parser in C. It can be easily integrated into resource-limited or embedded projects. Most JSON parsers offer you a bunch of functions to load JSON data, parse it and extract any value by its name. jsmn proves that checking the correctness of every JSON packet or allocating temporary objects to store parsed JSON fields often is an overkill.

10. MQTT-C – JSON parser in C

MQTT-C is an MQTT v3.1.1 client written in C. MQTT is a lightweight publisher-subscriber-based messaging protocol that is commonly used in IoT and networking applications where high-latency and low data-rate links are expected. The purpose of MQTT-C is to provide a portable MQTT client, written in C, for embedded systems and PC's alike.

11. MQTT – Eclipse Mosquitto

Eclipse Mosquitto is an open source (EPL/EDL licensed) message broker that implements the MQTT protocol versions 5.0, 3.1.1 and 3.1. Mosquitto is lightweight and is suitable for use on all devices from low power single board computers to full servers. The MQTT protocol provides a lightweight method of carrying out messaging using a publish/subscribe model. This makes it suitable for Internet of Things messaging such as with low power sensors or mobile devices such as phones, embedded computers or microcontrollers. The Mosquitto project also provides a C library for implementing MQTT clients, and the very popular mosquitto_pub and mosquitto_sub command line MQTT clients.

Mosquitto is part of the Eclipse Foundation, is an iot.eclipse.org project and is sponsored by cedalo.com.
