![]() ![]() Use "qrcp -help" for more information about a command. l, -list-all-interfaces list all available interfaces when choosing the one to use k, -keep-alive keep server alive after transferring i, -interface string network interface to use for the server d, -fqdn string fully-qualified domain name to use for the resulting URLs However, because the scanner is emulating a keyboard it outputs keyboard keycodes, not ASCII, and so the FNC delimiter is output as an Alt + 0 2. This is an ASCII 29 code also called a Group Separator. When it scans a 2D Barcode (QR code) it outputs the scanned string which contains a FNC1 delimiter. Now your 3310g is in serail emulation mode, note new /dev/ttyACM0 or /dev/ttyUSB0 device. The scanner is set up as a keyboard emulator. You could potentially scan the QR code from the book using a webcam. Grab a Quick Start Guide, scan 'USB Serial'-mode barcode, then 'Save' barcode to make this setting permanent. It is able to recognise a number of specific types of QR code including web links, email addresses/messages, SMS messages and telephone numbers. QtQR can read QR codes from image files or from a webcam. c, -config string path to the config file, defaults to $HOME/.qrcp A graphical interface for creating and reading QR codes. Version Print version number and build information. Send Send a file(s) or directories from this host qrcp.json file in the user home directory. The application configuration is stored in a hidden. You may also choose any (0.0.0.0) as the network interface, in which case the file becomes available not only to everyone on the same network, but also from external networks (as long as the port is not blocked by your firewall or router). It's worth noting that in case you have multiple network interfaces, the first time you run qrcp it will ask you to choose the network interface to use for the file transfer (the one you need to choose is usually in this form: enp3s0 or eth0). When you run the receive command, scanning the QR code on your mobile device opens a web page that lets you pick files from your mobile device to transfer them to your desktop on which you ran qrcp. Or, to receive the files in a specific directory: To receive file from the mobile device to your desktop over Wi-Fi, in the current directory, use: To send a file to a mobile device from your desktop over Wi-Fi, run qrcp with the file as its argument, like this (example):ĭo the same to send a folder, e.g. So what about sending multiple files at once or even folders? qrcp supports that too - in such cases, it automatically creates a zip archive of the files or folders you want to transfer, and deletes the zip archive once the transfer is completed.

Once the transfer is completed, the web server is automatically stopped.įor transferring files from a mobile device to a desktop, qrcp serves a web page that can be used to choose the files you want to transfer.īoth when transferring files from a desktop to a mobile device and the other way around, a URL is shown in the terminal so you can type that instead of scanning the QR code if you wish. As a code generator for any other accounts that support authenticator apps. When the QR code is scanned, the download begins (or you can open the URL scanned by the QR app in a web browser and the download will begin then). The application binds a web server to the address of your Wi-Fi network interface on a random port (though the port can be specified if you want). It's available for Microsoft Windows, macOS and Linux. Sound interesting? This is useful for generating URL QR codes, among other things.Qrcp is a command line tool to transfer files from a desktop to a mobile device (and the other way around) over Wi-Fi, by scanning a QR code. This is a Qt based software which let’s you generate QR codes easily, scan an image file for QR codes and decode them or use your webcam to scan a printed one.
