Bluetooth wireless technology has become an indispensable part of how devices communicate with one another today, from pairing your wireless headphones to connecting keyboards or even smartwatches. But not all Bluetooth devices are created equal. Each version of Bluetooth—from 1.0 to the current 5.4—brings improvements in range, speed, energy efficiency, and compatibility.
So, how can you determine which Bluetooth version is supported on your Windows computer or device? Whether you've encountered compatibility issues with your peripherals or you’re simply curious, this guide will walk you through the process and help you decode the cryptic “LMP” (Link Manager Protocol) numbers into their corresponding Bluetooth versions.
Let’s simplify the mystery of Bluetooth and uncover what’s hiding under the hood of your Windows device.
Bluetooth versions aren’t just numbered upgrades for show. Each iteration introduces new features:
The LMP number represents the highest Bluetooth Core Specification your device supports.
For example:
Fix: Verify your system’s LMP version and upgrade to USB Bluetooth external adapters that support newer versions, if needed.
Fix: Update your Bluetooth drivers in Device Manager or try moving the device closer.
Fix: Upgrade the Bluetooth module, or check if the accessory’s codecs are supported.
If you’ve discovered your Bluetooth version already—ask yourself: is it time for an upgrade? With Bluetooth tech evolving rapidly, maybe now’s the time to future-proof your setup.

So, how can you determine which Bluetooth version is supported on your Windows computer or device? Whether you've encountered compatibility issues with your peripherals or you’re simply curious, this guide will walk you through the process and help you decode the cryptic “LMP” (Link Manager Protocol) numbers into their corresponding Bluetooth versions.
Let’s simplify the mystery of Bluetooth and uncover what’s hiding under the hood of your Windows device.
Why Bluetooth Versions Matter
Bluetooth versions aren’t just numbered upgrades for show. Each iteration introduces new features:- Speed & Data Transfer: Later versions (like Bluetooth 5.0) offer faster data rates and broader bandwidth.
- Range Improvements: Bluetooth 4.0 and onwards brought significant enhancements to connectivity distance.
- Energy Efficiency: Versions equipped with Bluetooth Low Energy (LE)—starting with 4.0—consume considerably less power, ideal for IoT devices and wearables.
- Compatibility: Some accessories require a minimum version to function properly. For example, a Bluetooth 5.0 accessory might work on older Bluetooth specifications but likely with reduced functionality.
How to Check Your Bluetooth Version on Windows
Windows doesn’t display your Bluetooth version front and center, but with a little detective work in Device Manager, you’ll find exactly what you’re looking for. Here’s the step-by-step breakdown:1. Open Device Manager
- Right-click on the Start menu (or press
Win + X) and select Device Manager from the list. - Device Manager is your Windows control hub for analyzing and managing all system hardware.
2. Expand the Bluetooth Section
- In the Device Manager window, locate Bluetooth and click the arrow ▶ to expand it.
- You’ll see a list of Bluetooth-related devices, including your system's Bluetooth radio (critical for identifying the version).
3. Identify Your Bluetooth Radio
Look for a device name that references the Bluetooth radio module from a manufacturer. It might be named something like:- Intel(R) Wireless Bluetooth(R)
- Realtek Bluetooth Adapter
- Qualcomm Atheros Bluetooth Module
4. Access Bluetooth Radio Properties
- Once you’ve identified your Bluetooth radio, right-click on it and select Properties.
- In the Bluetooth adapter's Properties window, switch to the Advanced tab.
5. Locate the LMP Version (Link Manager Protocol)
Under the Advanced tab, you’ll see a section called Bluetooth Radio Information. Look for a field labeled “Firmware Version,” followed by an LMP number.The LMP number represents the highest Bluetooth Core Specification your device supports.
Decoding Your Bluetooth Version
| Here’s how to map the LMP number to the associated Bluetooth version: | LMP Version | Bluetooth Core Specification |
|---|---|---|
| LMP 0 | Bluetooth 1.0b (Withdrawn) | |
| LMP 1 | Bluetooth 1.1 (Withdrawn) | |
| LMP 2 | Bluetooth 1.2 (Withdrawn) | |
| LMP 3 | Bluetooth 2.0 + EDR (Withdrawn) | |
| LMP 4 | Bluetooth 2.1 + EDR (Deprecated) | |
| LMP 5 | Bluetooth 3.0 + HS (Deprecated) | |
| LMP 6 | Bluetooth 4.0 | |
| LMP 7 | Bluetooth 4.1 | |
| LMP 8 | Bluetooth 4.2 | |
| LMP 9 | Bluetooth 5.0 | |
| LMP 10 | Bluetooth 5.1 | |
| LMP 11 | Bluetooth 5.2 | |
| LMP 12 | Bluetooth 5.3 | |
| LMP 13 | Bluetooth 5.4 | |
| LMP 14 | Bluetooth 6.0 (Predicted/Upcoming) |
- If LMP 9 is listed, your device supports Bluetooth version 5.0.
Troubleshooting Common Bluetooth Issues
Here are a few issues you might encounter, along with quick fixes:1. Accessory Not Pairing
Cause: The accessory requires a newer Bluetooth Core Specification your system doesn’t support.Fix: Verify your system’s LMP version and upgrade to USB Bluetooth external adapters that support newer versions, if needed.
2. Spotty or Dropped Connections
Cause: This could be related to device interference, outdated drivers, or a weaker Bluetooth specification.Fix: Update your Bluetooth drivers in Device Manager or try moving the device closer.
3. Poor Audio Quality
Cause: A mismatch in Bluetooth profiles (e.g., outdated profiles like SBC instead of aptX/HD codecs).Fix: Upgrade the Bluetooth module, or check if the accessory’s codecs are supported.
What If I Want to Upgrade My Bluetooth Version?
If your Bluetooth version feels outdated, there’s still hope:- Option 1: Update Drivers – Sometimes driver updates can unlock newer features or tweak compatibility!
- Option 2: Add a Bluetooth Dongle – Affordable USB adapters can provide support for Bluetooth 5.0 or 5.3 on almost any Windows laptop or desktop.
- Option 3: Hardware Upgrade – Integrated Bluetooth modules (especially in older laptops) may require a replacement or a motherboard upgrade for enhancements.
Conclusion
Knowing your Bluetooth version and its compatibility with modern devices can save you time, frustration, and money. Whether you're troubleshooting or ensuring that your upcoming purchase works seamlessly, identifying the LMP version of your Bluetooth is a simple process that gives you valuable insight into your PC's technical capabilities.If you’ve discovered your Bluetooth version already—ask yourself: is it time for an upgrade? With Bluetooth tech evolving rapidly, maybe now’s the time to future-proof your setup.
