Documentation on how to use Bluetooth functionality #413

Open simoneruffini opened 9 months ago

simoneruffini commented 9 months ago

Hi I don't understand how the bluetooth functionality works, is there some documentation? Does it emulate a virtual keyboard?
I see from dmesg that when my android device connects to my host linux PC, it creates a virtual input in /dev/input/eventxx but I can't use it.
I tried using libinput debug-events /dev/input/eventxx but it returns nothing when I scan a qr code.
Is it possible that it doesn't work because I'm running wayland?

Unfortunately there is no documentation at the moment, and this is a feature I don't use myself 😬

Bluetooth functionality was added with https://github.com/markusfisch/BinaryEye/pull/363 by @KamaleiZestri, who may be able to shed some light on this?

But I really doubt that Wayland is a factor here 🤔

Bluetooth functionality was added with the RFCOMM protocol with UUID 8a8478c9-2ca8-404b-a0de-101f34ab71ae, so the device it is connected to will have to run a server of some kind to properly connect and send the scans.

My initial use case only involved Windows, so I ended up writing something quick that only works on Windows. Trying to get time soon to rewrite it for both Windows and Linux.

If anybody is interested I've written a basic tool which seems to work In Rust https://github.com/sean666888/bin_eye_bt_receiver It only works on Linux, as far as I know, and only works with Xorg for the keyboard output stuff, but it seems to work when I tested it. For the time being you will have to compile it yourself if you want it and you will need to install these libraries "sudo apt install libdbus-1-dev pkg-config libxdo-dev" A lot of the code is copy, paste from examples on the various libraries I used I'm currently trying to clean it up.It's good practice for doing stuff in rust.

Hi. Is there any option to work BinaryEye from Realme X3 Superzoom device with Windows 11 laptop via Bluetooth? I need to scan codes with phone and send to host which is laptop. I have already configured "Forward scans with Bluetooth" and set my laptop as a host but after scanning code app shows "Could not connect to a Bluetooth device".

Generally, i want BinaryEye to open automatically via Bluetooth on my laptop web browser order in BaseLinker after scanning generated order code.
