# Wifi Modes --------------------------------

The WifiBackpack modules uses 2 modes for its Wifi connection.

1. Access point (AP mode) - This mode turns the ESP wifi module into an access point and be able to accept client connections and provide IP address via DHCP. This mode allows your Phone, Tablet or PC to connect to the WifiBackpack directly using wifi without the need for Wifi networks. This is useful during initial set up to connect the WifiBackpack to your network or when you want your machine to be on stand alone mode ( when showing off machine or in a trade show/classroom). Wifi module will automatically turn on this mode when it cannot find any known Wifi networks. Default SSID is Wifi-Backpack.

2. Client Station - This mode is selected when connecting your WifiBackpack module to your home or office Wireless network. This will allow you to search for available Wifi networks and join them. Wifi module will revert back to AP mode if it cannot connect to previously configured Wifi network.

After configuring click save.

2. Disconnect/reconnect power to main controller board to apply the settings. Hitting reset on the main controller will not reset the WifiBackpack. After boot up, the LCD should display the IP address of either AP mode or Station mode (if successfully connected to wireless network). In some instances the Wifibackpack boots up ahead of the Main controller/LCD and the IP address is not displayed, you can hit the reset button on the back of the wifibackpack or have some other means to determine the IP of the Wifibackpack.

If you configured the backpack for Station Mode but IP address shown is the default for AP mode then the WifiBackpack was not able to connect to the intended wireless network. Run Setup again as described above.
