esp8266 module -AP mode

esp8266 STATION mode

WI-FI Modes

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

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