Context Connecting two devices using a TCP (Transmission Control Protocol) socket allows them to exchange data reliably over a network. TCP ensures that data packets are delivered in order and without loss, which makes it suitable for applications such as chat systems, file transfers, or real-time communication. Description Using HarmonyOS Network Kit , you can establish a TCP socket connection between your smartwatch and another device (such as a computer) within the same local network.
