Firmware for M5Stack Cardputer that passively scans networks and idicated when new open networks are present

App scans in background all networks around you and plays short three beeps whenever a new open network is discovered. For networks that were already caught that beep sounds every five minutes. After five minutes firmware removes stale old networks from the list.

On start it plays a simple boot animation!
