AP Mode

AP Mode allows smartphone to access our device WIFI directly,therefore  can achieve remote control although there is no need of router connection.

Go to WIFI settings of your Smart phone/Tablet/PC and select the ssid shown below to connect our device.

SSID : GKWAVE-B4CH-xxxxxx

PW:xxxxxxxx

Default IP:192.168.4.1(Enter this IP in your browser and go for the control page)

STA Mode 

In STATION Mode our device and smart phone both are connected to the router .So user can access our device through router.

Step:1

Save your Router User name and password in Networking configuration page through AP default IP:192.168.4.1

Step:2

Once saved, our device automatically restart and connected to the STA mode.

Step:3

To find our device IP, first open your router page

Ex:192.168.1.1

Click, LAN tab on router page-Find assigned IP address for our devicewhich is corresponding to our device MAC address.

using this IP  you can access the control page.

Another and simplest way to find assigned IP through our Android APP
