this is a little File Browser for the OdroidGo via the Webbrowser.
You can choose between Accespoint mode or connect to an existing Wifi:
The Web File Browser will create an Access Point with,
SSID: odroidgo
PSK: odroidgo
Webadress: http://192.168.4.1 (if you connected to the access point)
or
it will connect to the Wifi which was defined in the WIFI.TXT in the SD-Card root directory.
Webadress: http://displayedIPonOdroidGo or http://ordroidgo.local
WIFI.TXT
Code: Select all
MyWifiName
MyWifiPSK
You can create folders, delete and upload new files.
