I'll be pleased to help, if you can't get it to work for the first time.
(please don't give bad rating if your router/firewall/network doesn't permit connections between your Android and PC)

How it works:
> PC listener creates a socket connection
> Broadcasts a UDP message on port 22633 (so this port should be allowed on your PC/Network)
> Android pp looks for the message and detects PC's IP address
> App establishes TCP connection to PC
> Any Barcode scanned is sent to PC over this connection
