no wifi name

I have uploaded the code to my lolin nodemcu v3 with success. But when I switch on my Wi-Fi on my android tablet, the SSID of the nodemcu does not appear...before I upload the code, the SSID is Fairylink...so I guess it's not the board problem...maybe u can help?

Hidden (choices: YES or NO): This is important! By default, the WiFi is hidden, that means to connect to the espbug you must manually enter the ssid and password. When an attack occured, the WiFi is hidden again, so you should connect to the device automatically with the same station. However, during an attack you want the WiFi to be visible, so set this to NO.
