The CoAP protocol is an IoT protocol that supports communication between constrained devices operating in constrained networks. Therefore, the CoAP protocol is designed to be very lightweight and uses the UDP protocol for data transmission, making it well-suited for constrained network environments. CoAP operates in a manner similar to HTTP, allowing operations on abstract resources … Read more
Author: EMQ Technology With the development and popularization of IoT technology, more and more smart devices are equipped with network connectivity and data transmission capabilities. Due to the complexity and diversity of IoT scenarios, factors such as hardware conditions at the device end, network stability, traffic limitations, device power consumption, and the number of devices … Read more
Author: HFK_Frank Original link: https://blog.csdn.net/acongge2010/article/details/79142380 MQTT Protocol MQTT (Message Queuing Telemetry Transport) was originally developed by IBM as an instant messaging protocol. The MQTT protocol is designed for communication between remote sensors and control devices with limited computing power operating in low bandwidth and unreliable networks. The advantage of the MQTT protocol is that it … Read more
