WiFiEsp example: ConnectWPA
|
|
|
|
This example connects to an encrypted WiFi network using an ESP8266 module.
|
|
Then it prints the MAC address of the WiFi shield, the IP address obtained
|
|
and other network details.
|
|
|
|
For more details see: http://yaab-arduino.blogspot.com/p/wifiesp-example-connect.html
