/* Very basic example showing usage of access point mode and the DHCP server.
|
|
|
|
The ESP in the example runs a telnet server on 172.16.0.1 (port 23) that
|
|
outputs some status information if you connect to it, then closes
|
|
the connection.
|
|
|
|
This example code is in the public domain.
