Channel & Data Support

​
Connection Handling

  1. Ping/Pong Mechanism:
    • Server sends a ping every 10 seconds.
    • If no pong is received within 20 seconds, the connection is automatically closed.
    • Ensure your WebSocket client responds to pings with pongs — most libraries handle this automatically, but verify your implementation.
  2. Planned Disconnections (Deployments & Reboots):
    • System reboots or deployments may temporarily disconnect active connections.
    • Your application should automatically reconnect on disconnection. Use exponential backoff to avoid overwhelming the server during widespread disconnections.
