There are two different scenarios how a Prota might be stuck in AP mode.
1. Prota wasn't connected to a network yet
In this case, a user should try to connect to Prota's SSID through the WiFi settings of the smart device (smartphone/tablet) and then set the WiFi for the Prota in the Settings app on Prota Space.
For further information, please refer to the guide.
2. User has manually entered into AP mode
If you don't want to change the WiFi, please hover over the top for about 10 seconds. When the LED on top flashes green, the Prota will reconnect to the previous network.
