Android Question B4X - Barcode to PC

[samikinikar]

Hello,

There are many examples on generating barcodes, reading barcodes and so on. Is there any way that the read values can be passed to the PC using WIFI to any other application on PC , like excel, POS, other application and so on, so that the phone acts as a barcode device.

Ex. : https://barcodetopc.com/#features

The result from the barcode is just some digits. You can use many ways to send the data right? MQTT, HTTP, Serial, etc.

I have created a B4A app which exactly do this.
This app scans the barcode from an Android smartphone and add/queue the scanned barcodes to a temporary table. A timer is activated in POS system that query the barcodes from the temporary table and insert it into the sales list.
There are 2 pieces of B4J apps. One is the POS system and another is a Web API Server where the B4A app call the API. The Web API server and POS software shares the same SQLite database.

I have tried this device :

In theory, you can use the dongle as a USB keyboard and send to it the strings from your smartphone over BLE connection. But the documentation is written in Chinese, and it's all Greek to me. I can enumerate the services, but at this time, i can't send a string to the dongle . If someone have the solution ? ???
