什么是端口 5683?
Port 5683 is the standard port for CoAP (Constrained Application Protocol), a lightweight RESTful protocol designed for IoT devices with limited resources. CoAP is used by sensors, actuators, and embedded devices to communicate over low-power networks like 6LoWPAN and LTE-M. It is the IoT equivalent of HTTP, providing GET/POST/PUT/DELETE semantics over UDP.
