ping on an interval shorter than that. Protocol-level WebSocket ping frames that client libraries send automatically do not reset the idle timer — only JSON-RPC messages do.
The server also pings every 15 seconds, so a healthy but quiet connection still carries traffic. If you see nothing at all for over a minute — no notification, no ping — assume the connection is dead and reconnect. See Handling Reconnects for the full strategy.
