# 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.


# Connect using AP mode for initial setup  --------------------


Upon initial power of the WifiBackpack it is set up for AP mode, this allows you to directly connect to it using any smartphone, Tablet or PC with Wifi. You can also change the mode to Client Station (to connect to your Wifi network) by using the web control setup.


1. Power on the LCD with WifiBackpack. Wait for 15 seconds for Wifi module to initialize AP mode. By this time the main 3D printer controller and LCD has initialized and will display the IP address of the WifiBackpack. Default IP address for AP mode is 192.168.0.1


2. Open your Smartphone, Tablet or PCs Wifi and look for SSID named "Wifi-Backpack". Connect to it using default password 12345678


3. Once connected, open a browser and the captive portal should automatically redirect you to the main web control page. For IOS devices wait for the captive portal to redirect, no need to open any browser. If captive portal fails to redirect, open a browser and point to 192.168.0.1


4. You should see the main web control page at this stage and should be able to control the printer. Formatting may be different than shown, small screen devices will re-arrange the windows.



5. Run initial setup by clicking on Blue horizontal lines on the upper right corner of the page then click "Setup" on the drop down menu. This will also allow you to configure your module for Client Station mode and connect to your Wireless Network.


6. Click Start Setup.



7. Select Firmware on Main controller board, select Baud Rate configured on Main Controller(must match or will prevent UART communications) and select ESP name (you can leave this as is).  Click SET to apply the changes.



8. Define ESP role - For AP mode leave as is. Change other entries as needed. Default Password for access point is 12345678. Click SET to apply the changes.



9. Define ESP role - To connect to your Wireless Network change to Client Station. Click SET. Click on the magnifying glass icon to select available wireless networks. Click SET after selecting. Provide password to join then click SET. Click continue.



10. Select YES for both for WifiBackpack



11. Finish Setup




# Configure Preferences --------------------

 

1. The Preferences page will setup details about your printer. Click on the horizontal blue bars at the upper right hand corner of the page. Select "Preferences". 

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 192.168.0.1 for AP mode then the WifiBackpack was not able to connect to the intended wireless network. Run Setup again as described above.
