Does bluetooth RFID UHF reader work in keyboard emulation mode on Android OS?

Good day! Please help with a question regarding the operation of a bluetooth RFID UHF reader in keyboard emulation mode on Android OS - you need the ability to read the UHF tag number in any active input field on the device, respectively, in any application of this device.
For example, we have such a bluetooth RFID UHF reader:
https://ru.aliexpress.com/store/product/1-meter-UH...
Turn on the reader-> Open the list of active bluetooth devices on your smartphone-> See our device-> Trying to connect -> Connection failed.
To make it work, you need to download a file from the manufacturer of the reader with the apk extension to your smartphone, and then install it. Through this Chinese android application, he connects, and reads the label there. There is no way to copy the read tag number from there, the number is not highlighted, not copied, full PPC ...
But, even if, for example, you copied the number, then you need to open the Web application I need and paste this number there in order to recognize the product assigned to this tag number - a lot of unnecessary and long actions. In isolated cases - this would not be a problem, they could endure.
But in my case, although you need to read one label at a time, but many times per work shift - like a conveyor, where goods arrive one after another, at a certain interval.
Therefore, I need to be able to read the tag number directly into the active field of a notepad, web application, browser, etc. Manufacturer (Chinese) shrug, say that's all they have, like, sorry.
I tried to connect a USB RFID UHF reader to a smartphone, but of course he does not see it, although the device is powered, but there is no software for wired readers. Therefore, also a bummer.
Are there really no RFID UHF readers to work as a handheld barcode scanner??? Connected by wire or bluetooth and work for yourself, scan the tag as and wherever you want ....
Actually, I got stuck with this issue very seriously ... help me out, brothers

Answer 1

Well, there is a usb connection that suits you, you can do this. Find a UHF reader that can be connected to Arduino, with UART\SPI interface.
Take Arduino Leonardo or Pro Micro - it has usb host. Arduino will be defined as a keyboard. In an Arduino loop, poll the UHF reader and send the data via USB.

Hey! If you manage to get the code for communicating with the reader from the apk that comes with the kit, then you can wrap it in a custom android keyboard.
Those. the approach is the same as for Speech-to-Text in the standard Google keyboard, only instead of a voice that is converted to text, there will be data from the reader.
Only this is all in theory and, perhaps, the approach is not working.
