Qt6 CoAP client module

Constrained Application Protocol (CoAP) is an IoT protocol that is specifically designed for M2M data exchange between constrained devices (such as microcontrollers) in constrained networks. The interaction model of CoAP is similar to the client/server model of HTTP, but unlike HTTP, it uses datagram-oriented connectionless transport such as UDP, which leads to a very low overhead and allows UDP broadcast and multicast to be used for addressing. At the same time it provides lightweight reliability mechanisms and security. Qt CoAP implements the client side of CoAP. By default, the transport layer uses QUdpSocket and QDtls for security. Alternative transports can be used by implementing the QCoapConnection interface.
