Recently at Exadel, we encountered an interesting challenge for IoT developers. As IoT applications gain so much momentum, there are more and more options on how to develop them. For device communication, two specialized competing protocols stand out: Message Queue Telemetry Transport (MQTT) and Constrained Application Protocol (CoAP). Both are designed to be lightweight and … Read more
IoT Communication Protocols Communication protocols can be considered a language, allowing two or more devices to communicate with each other. Just like there are rules for any system, communication protocols also follow a set of rules to pass meaningful information between devices. Communication protocols are crucial in distributed systems, where different parts of the same … Read more
Currently, most IoT modules on the market support protocols such as TCP, UDP, CoAP, LwM2M, and MQTT. Among these, there are both transport layer protocols and application layer protocols, with many protocols available for different scenarios. However, when designing a product, usually only one protocol is needed, so how to choose a protocol that fits … Read more
