# SendTo



Project of **SJTU-CS339 Computer Networks**.



## Introduction



SendTo is an end-to-end file transfer application, which supports device detection by UDP and Bluetooth and file transferring by TCP.



SendTo 是一款端到端的文件传输应用。它支持局域网设备感知（UDP协议）、近距离设备感知（蓝牙），并可以传输任意大小的文件（TCP协议）。



## Features



* Multiple device perception methods

* Transfer files of any size



## Build & Run



If you just want to use it, feel free to skip to **Usage **section.



* IDE: Qt Creator 4.15.0(Community)

* Kits: Desktop Qt 5.12.11 MSVC 2015 64bit (MSVC is necessary. Without MSVC Bluetooth is not supported)

* Operating System: Windows 10, 11



## Usage



The executable file is in [Executable](https://github.com/guanrenyang/SendTo/tree/master/Executable) folder. You just need to double click on the `SendTo.exe` file to use it. All runtime dependencies have been packaged in the folder.



### Device Selection



SendTo provides three ways to specify a device:



* In LAN (by UPD broadcasting)

* Nearby (by Bluetooth)

* Specify an IP address



#### In LAN



In LAN mode could detect devices in the same local area network.



Click the "局域网" button(the 1st in the yellow rectangle) to switch to **In LAN** mode. Click the "重新扫描" button(the one in red rectangle) to do a scan. After that, select a device in the drop down box(upper in the red rectangle).

#### Nearby



**Nearby** mode could detect devices around, which works in the similar way as **In LAN** mode.



Click the "蓝牙" button(the 2nd in the yellow rectangle) to switch to **Nearby** mode. Click the "重新扫描" button(the one in red rectangle) to do a scan. After that, select a device in the new window.

#### Specify an IP address



SendTo allows you to specify an IP address to send to.



Click the "指定接收者" button (the 3rd in the yellow square) and enter the receiver's IP address in the corresponding editable text box. 



The local IP address is also displayed on this interface. If you are the receiver, you can tell it to the sender.

### Files Selection



* Drag and drop: SendTo provides a drag-and-drop interface for selecting files, just drag files and drop them on the box in the lower half of the window(in big red rectangle)

* Double click delete: The file to be sent will be displayed in the box in the lower half of the window, double-click the file name to delete the file from the list
