It is used to control equipment accessible via WiFi in a special mode - each controlled device has its own WPA2-protected WiFi AP with hidden ESSID.
The controlled device remains silent until the controller connects to it. When the system works, the controller needs to connect to various controlled devices in a sequence. It can be easily done with:
Code: Select all
wlan.connect('essid', 'password')
