What Bluetooth version is on my Dell laptop?

I recently got curious about the Bluetooth capabilities of my Dell laptop. I understand that various devices come with different versions of Bluetooth, and I’ve been trying to figure out precisely which Bluetooth version my Dell laptop supports. Knowing the Bluetooth version is important to me because it impacts compatibility with other Bluetooth devices, such as headphones, speakers, and even my smartphone. I’ve noticed that different versions offer varying speeds, ranges, and features. This information would help me determine the efficiency and range I can expect when using Bluetooth technology. However, I’ve found it challenging to locate this specific detail, even after checking some settings and specifications. How can I definitively find out what Bluetooth version is on my Dell laptop?

I faced this issue too and finally managed to figure it out. Here’s my detailed approach:

  • Access Device Manager: Click on the Start button, type “Device Manager” in the search bar, and open it.
  • Find Bluetooth Section: Scroll down and find the “Bluetooth” section. Expand this section by clicking the small arrow.
  • Identify Bluetooth Adapter: Look for the Bluetooth device (e.g., Intel Wireless Bluetooth, Qualcomm Atheros Bluetooth). Right-click on it and select “Properties.”
  • Check Details: In the Properties window, go to the “Details” tab and, from the dropdown menu, select “Bluetooth version.” Here, you might see the LMP version (Link Manager Protocol).

  • Use LMP Table: The LMP version can be cross-referenced with a Bluetooth version table:

  • LMP 0 – Bluetooth 1.0b

  • LMP 1 – Bluetooth 1.1
  • LMP 2 – Bluetooth 1.2
  • LMP 3 – Bluetooth 2.0+ EDR
  • LMP 4 – Bluetooth 2.1+ EDR
  • LMP 5 – Bluetooth 3.0+ HS
  • LMP 6 – Bluetooth 4.0
  • LMP 7 – Bluetooth 4.1
  • LMP 8 – Bluetooth 4.2
  • LMP 9 – Bluetooth 5.0

This way, I was able to accurately find out that my laptop supported Bluetooth 4.0.

To find out the Bluetooth version on your Dell laptop, I followed these steps, and it was pretty straightforward:

  1. Open Device Manager: Press the Windows key + X to open the power user menu and select ‘Device Manager.’
  2. Expand Bluetooth Section: In Device Manager, look for the ‘Bluetooth’ section and expand it by clicking the arrow next to it.
  3. Find Bluetooth Adapter: Locate the Bluetooth adapter in the list (it might be named something like ‘Intel Wireless Bluetooth’ or ‘Qualcomm Atheros Bluetooth’), then right-click on it and select ‘Properties.’
  4. Check Driver Details: In the Properties window, go to the ‘Advanced’ tab. Here, you should find the ‘Firmware’ or ‘LMP’ version.
  5. Determine Bluetooth Version: Compare the LMP version number with a Bluetooth version table you can find online to determine which Bluetooth version your adapter supports.

For instance, if the LMP version is 6.x or 7.x, you have Bluetooth 4.0. It’s a detailed process, but it accurately reveals your Bluetooth version.

I had the same question about my Dell laptop and found a simple method to figure it out. Here’s how I did it:

  1. Search for ‘Run’: I pressed Windows + R to open the Run dialog box.
  2. Enter ‘dxdiag’: Then, I typed ‘dxdiag’ and hit Enter. It opened the DirectX Diagnostic Tool.
  3. Save Information: I clicked on ‘Save All Information’ to create a text file with all my system details.
  4. Locate Bluetooth Info: In that text file, under ‘System Information,’ I found the details about my Bluetooth adapter, including the version.

It was surprisingly easy, and I was thrilled to see all the precise details.
