Pressing and releasing the (D) Mode Switch Button will toggle the device between D2D (Device-to-device) and Infrastructure mode.
In D2D or Hotspot mode the GS-911 serves as a Wifi Access point for other devices to connect to. In Infrastructure mode the GS-911 device connects to an existing Wifi Access Point.
When toggled to Infrastructure mode, the device will attempt to connect to the last successful previous connection. Otherwise it will continue scanning for previously known connections.
If sound is enabled, a succesfull connection to WiFi Infrastructure will emit 2 beeps.
