May limit publisher and time to send message if look like spammer Maybe server need wait a time (short time) if detect mutiple publish messages same to one client and send a batch of messages instead of send a single message. The API description is broken down into three short chapters. k-Means is not actually a *clustering* algorithm; it is a *partitioning* algorithm. To establish websocket connection between app and device, both should be connected to same local area network (LAN) or directly connected with each other using microcontrollers hotspot. A websocket client module that implements RFC6455 (version 13) and provides a simple interface to send and receive messages. Objectives. Just for you. IO is built on top of the WebSockets API (Client side) and Node. Usually communication standards like UART/RS232 are used to establish an easy to use connection, while other standards like USB are difficult to handle and tend to be very complicated.
