Connect Your Smartphone

Download the Barcode to PC to Your Smartphone

1. Download the Barcode to PC application to your smartphone from the Play Store or App Store.

2. Open the application on your smartphone.

3. If your smartphone and server device use the same network, your smartphone should seamlessly connect to your server device where you are running the Barcode to PC 'server'.
   
   

   When you first use your smartphone as a scanner device, you need to decide whether you will use QR codes or barcodes for identification in the future.
   For QR codes, an #LS Prefix must be set (for the 'Barcode to PC scanning application' ) for the devices to function correctly.
   See How to Set up the #LS Prefix for your Scanner.

   
   

   Even if your computer has a wired connection, your smartphone should automatically connect to the device as long as both are connected (wired or wirelessly) to the same internet access point.

Possible causes of connection problems

1. The smartphone application's version does not match the desktop application's version.

   Solution

   To avoid version incompatibility issues, leave the Enable automatic updates to switch on inside the Info tab.

   According to the provider, at least the first numbers of the smartphone and desktop versions should be the same. For example, the v3.0.0 smartphone version is compatible with the v3.2.0 desktop version. 

2. Your server computer is not discoverable. 

   Solution

   Refer to the guide featured on the Barcode to PC's website to make your computer discoverable on trusted networks.

   Server Computer Has Wired Connection

   Inside Network & Internet settings, select Ethernet from the side menu.

3. Your firewall is blocking the smartphone application.

   Solution

   First, add the Barcode to the PC server executable to the firewall exceptions and allow connection to ports 57891 TCP and 5353 UDP. Then, follow the steps in the firewall settings guide featured on the Barcode to PC's website.

   Opening Port 5353 UDP Is Not Necessary

   According to Barcode to PC's FAQ, allowing connection to port 5353 UDP is not essential. If you do not accept connections on this port, you must manually add the server to the smartphone.
