AP+Client Mode (For experienced users only)

Module is able to connect to an existing WiFi station (e.g. your home network). By entering the configuration interface, you can set the AP+Client mode. In this mode you can find your network and connect to it. In this way, module can be accessed from any device, that is connected to the same network, even via an ethernet cable.
If you are connected to an existing WiFi station, the module will receive second IP address. You can find such IP address in the configuration interface.
You can connect to the interface from the second IP address when accessing from your network. You can also access the internet or module at the same time.

  2. Enter the WiFi Client section in the web interface.
  3. Click the „Switch to AP+Client mode“ (if not already).

  5. In the WiFi Association select Wi-Fi network you want to connect.
  6. Enter password of the Wi-Fi network (if required).
  7. Click the Connect button and wait for the success notification.
  8. Remember the address that will appear in the „WiFi address“ entry – this IP address should be used to connect the module through the network you are connected to.

3.1 Auto Turn-Off feature

To allow operation of the Wifi-Link module during a flight you can enable the Auto Turn-Off feature. This feature will automatically turn off the module if no device will connect to it (at the Access Point created by the module) or if the module itself will not connect to any infrastructure (any other WiFi network that pilot can program).

After power up of the model the module will start counting the time. If there is no connection until configured period of time the Status LED will turn Off which mean that the module is completely turned off. Then it is completely safe to fly with the model.
