BluFang: Rename Bluetooth Devices and See
What They're Actually Doing

Windows gives every Bluetooth device a name. Sometimes it's the product name. Sometimes it's a model number. Sometimes it's just "LE-Bose AE2" or "Bluetooth Device (RFCOMM Protocol TDI)" and you have no idea what it is anymore.

I have a dozen Bluetooth devices paired to my PC — headphones, a keyboard, a mouse, speakers, a game controller, a couple of things I've forgotten about — and half of them show up in Settings as something unhelpful. You can't rename them from the Bluetooth settings page. You can dig into Device Manager and edit the friendly name in the registry, but that's a multi-step hunt through HKLM that nobody wants to do repeatedly.

Just want the download? The BluFang tool page has the features, install steps, and FAQ in one place.

BluFang is a PowerShell script that lists all your paired Bluetooth devices, lets you rename any of them, and — while it's at it — shows you the connection details that Windows hides: signal strength, battery level, Bluetooth version, manufacturer, device class, and more.

What You See

Run BluFang and you get an interactive menu of every paired Bluetooth device. For each one, BluFang pulls:

• Friendly name — the one you can rename
• Bluetooth version — e.g., 5.2, 4.0+LE
• Manufacturer — Apple, Sony, Bose, Jabra, Logitech, etc. — resolved from the manufacturer code
• Device class — Audio/Video → Headphones, Peripheral → Gamepad, etc.
• Signal strength — RSSI in dBm
• Battery level — if the device reports it
• Connection status — connected or paired-only

This is all data that Windows has in the registry and WMI but doesn't surface anywhere in the UI.

Renaming

Select a device from the menu, type a new name, and BluFang writes it to the registry. The change takes effect immediately — no reboot, no re-pairing. Name your headphones "Sony WH-1000XM5" instead of "LE_WH-1000XM5". Call your keyboard "Keychron K2" instead of "Bluetooth Keyboard". Whatever makes sense to you.

Requirements

• Windows 10/11
• PowerShell 5.1 or 7+
• Must run as Administrator (registry writes to HKLM require elevation)
