Resolve Bluetooth connection issues on Dell XPS 15

My Dell XPS 15 and Nexus 5 just don’t get along. Updating to the latest Bluetooth drivers for the Broadcom-enabled embedded chipset resolved this.

Here’s how to update your Broadcom-based Bluetooth drivers in Windows 10:

  1. Visit the Bluetooth section of the Broadcom website
  2. Expand the WIDCOMM® Bluetooth Windows® Software for Windows 10 & 8, 64-Bit section
  3. Click on the Download button to the left of the WIDCOMM® Bluetooth Windows® Software for Windows 10 & 8, 64-Bit header
  4. Open the downloaded ZIP archive (e.g. BTW_12.0.1.940_win8_10_x64.zip)
  5. Run Setup.exe within the Retail Package directory of the ZIP archive
  6. You may be prompted by Windows SmartScreen, click the More info link and the Run Anyway button within this dialog
  7. Click the Upgrade option within the WIDCOMM Bluetooth Software dialog
  8. Restart the computer when prompted

That’s it. 🙂

Fix for stuttering, lag in Bluetooth mouse on Windows 10

Here’s how I fixed the stuttering and lag issue with my Logitech MX Master working with Windows 10 Home and Pro:

  1. Open up the System screen within the Control Panel (keyboard shortcut: Win+Pause/Break)
  2. Open Device Manager from the list of links on the left panel
  3. Expand the Network adapters section to list your network adapters (e.g. WiFi, Bluetooth, VPN, etc.)
  4. Double click your WiFi network adapter to open the Device Properties dialog (in my case this is a Dell Wireless 1830 802.11ac)
  5. Switch to the Advanced tab (if you cannot see an Advanced tab then close this dialog and double click the other Network Adapters until you find one that has it)
  6. Within the Property list select Bluetooth Collaboration
  7. Change the Value of the dropdown list from Auto to Disabled
  8. Click OK to save changes

That’s it!

The WiFi network adapter will restart the device so expect to lose network access for a moment before network access is restored. Happy days.

Update 1: Yeah the above helped but didn’t fix it entirely, somehow unticking the Enable pointer shadow option within the Mouse Properties dialog (open Start then type in Mouse) makes a big difference, I do still notice some stutter when copying files or using Google Photos.

Update 2: Uninstalling the Realtek AC’97 software from Add/Remove Software and restarting did wonders on-top of the above steps. No more stutter!
