- * This example demonstrate how to use asynchronous client & server APIs
- * in order to establish tcp socket connections in client server manner.
- * server is running (on port 7050) on one ESP, acts as AP, and other clients running on
- * remaining ESPs acts as STAs. after connection establishment between server and clients
- * there is a simple message transfer in every 2s. clients connect to server via it's host name
- * (in this case 'esp_server') with help of DNS service running on server side.
- *
- * Note: default MSS for ESPAsyncTCP is 536 byte and defualt ACK timeout is 5s.
