What is Auto AP and how do I use it? only support 3.4.16 and newer

Auto AP mode is designed to provide a setup wifi for you to connect to, if your Pi-Star device is not already on a network.

If Pi-Star does not detect a known wifi network within approximately the first 2 minutes of booting up, it will create its own wifi called Pistar-Setup. 

Using your computer/phone, you can then connect to the Pistar-Setup wifi. The password for this network is: raspberry

Once you have connected to the Pistar-Setup wifi, you will be able to pull up the dashboard. Make your wifi configuration changes. Save them, and reboot Pi-Star. It will not access the new network until you reboot.
