Hi.

I want to create one Android application that emulate the use of Barcode Scanners.
Transform Android phone into a Windows WiFi barcode scanner.
Emulate keyboard and pass escape characters.
Send barcodes to any Windows application as keyboard inputs.
Also the need to work as a keyboard to any windows application.
I understand need to use B4A and B4J to manage it.

Any idea how to work on that project.
Any walkthrough advise?

Thank you.

you can use AsyncStreams to send data between phone and pc via wifi connection.

[B4X] Network + AsyncStreams + B4XSerializator

Better implementation, based on B4XPages: https://www.b4x.com/android/forum/threads/b4x-b4xpages-network-asyncstreams-b4xserializator.119011/#content New video tutorial: This is a simple and important example. It demonstrates several good practices related to network...

what exactly do you want to do?
why do you want to emulate the keyboard?
do you want to control another application from your b4j app?

i wrote long time ago (5 years) a NES game pad emulator that is installed on an android device and send commands to a b4j server that performs keyboard presses emulations.

you may have a look at it, i think this is what you are looking for:

NES GamePad for Android

Wanna play retro NES games on your PC? Why not turn your Smartphone to an NES gamepad and play with it? Try NES GamePad for Android via b4a+b4j. GamePad is not 100% working, i have not put to much effort on it I just wanted to get something working for my kids to show them what i was playing...

or
use this idea to send the digital signature and client data to a server or PC

[example] [B4X] Control the desktop with your phone

This example shows how simple it is to create network solutions with B4J, B4A and B4i. In this case the network communication is based on UDP. It implements a remote desktop mouse, where the Android device or iOS device control the desktop mouse. The B4J app uses jAWTRobot library to control...
