Incorrect MAC address on windows logs

[Algorithmonaut]

Hey, thanks a lot for this tool!

I tried setting it up multiple times, deleting the BlueVein cfg and the bluetooth adapter's folder on linux before. I also tried pairing all the devices on linux first, and pairing all the devices on windows first. Still, it didn't worked.

When inspecting the logs on windows, here is what I see:

[2026-01-31 16:43:39] [BlueVein] Service installed successfully!

As you can see, CE:NT:RA:LI:RK is not a valid MAC address. I don't know if this is the root of my issue, or if this is inert.

Anyway, note that I'm using Atlas OS (a modded version of Windows, this may be what makes you program not work for me), Arch, and that may bluetooth adapter is the external TP-Link UB500.

I will boot back to Linux and update you on the content of the cfg.

Also note that the service is currently enabled on Windows, but not on linux.

Sorry if my issue is unclear.

Thanks!

Here is the content of the bluevein.json:

{
  "98:03:8E:6A:75:4D": {
    "devices": {
      "CE:NT:RA:LI:RK": {
        "mac_address": "CE:NT:RA:LI:RK",
        "classic": {
          "link_key": "ADA8D0FBDAA371EB24B988FDCC5EBDA9",
          "key_type": 4,
          "pin_length": 0
        }
      }
    }
  }
}

Note that when I paired the devices over Arch, everything was set up correctly in the json, but the keys weren't imported to windows.

I will try one last time, pairing the devices on linux first, and will provide window's logs

Here is the bluevein.json after pairing all devices on linux, will go back to windows and check the logs:

Here is the json (the wrong mac address reappeared after booting on windows, so the issues is clearly on windows' side):

Still does not work

Here are a part of the logs on Linux:

Sorry if my issue is confusing, and sorry for all the comments due to switching back and forth between linux and windows
