We also use websocket ping/pong to make sure the connection is alive. The client sends a ping every 5 seconds, and the server replies with a pong. The server does not send pings. Note: QWebSocket and QWebSocketServer handles ping requests internally, which means they automatically send back a pong response to the peer.

So far everything works as expected. Jan 24, 2017 · ping/pong works as specified in the RFC. An endpoint can send a ping frame via ws.ping() at any time after the connection is established.

WEBSOCKET_PING: The other side sent a ping message. WEBSOCKET_PONG: The dynamic memory model should be chosen, if the data buffers change or more than one parallel websockets are required. The static memory model is suitable for a fixed data buffer organisation (e.g. ping-pong buffering).
