It is possible to download

and store a file on device. The API name is 'StartDownFile'. This API

takes the Server parameter from where you want download it(Source) and where to store

it on device(destination), may be on USB or LFD's internal memory.

pluginSef.StartDownFile(source, destination);

Define the source and destination

Source can be a server location such as: ServerIP+'/UI/TC_App/DLTEST_BIG.zip' or other memory location

Destination

can be USB Disk attached to LFD Set($USB_DIR/sda1*/ DownFileName) or Internal memory of LFD(/mtd_down/common/DownFileName

or /mtd_down/widgets/DownFileName).

In case, user wants to save the downloaded file to USB

Stick attached to LFD Set, the Destination path should be inserted very

carefully. Since the destination path can be different as per the USB Stick

being used, one need to follow the instructions below:

Case 1:

Only One usb stick is plugged in to LFD Set:

Destination Path = $USB_DIR/sda/ or $USB_DIR/sda1/

Case 2:

Two usb sticks are plugged in to LFD Set:

      Destination Path = $USB_DIR/sda/ or $USB_DIR/sda1/ or $USB_DIR/sdb/ or $USB_DIR/sdb1/

================================================================

Please refer to attached sample application code.

The preferred location on internal memory is: “/mtd_down/common/FileName.zip”.

1. Create offline.html page

2. Place it to /mtd_down/common/HospitalityBrowser/offline.html

3. Add the code below:

Example:

netPlugin.Open('Network', '1.000','Network');

  netPlugin.OnEvent = onEvent;

 function onEvent(event, data1, data2){

           switch (event)  { 

    case 2:

                 if(data1 == 0) {

                    location.href = 'file:///mtd_down/common/HospitalityBrowser/offline.html';

                 }

               break;    

            } 

        }
