How to install the bluetooth on a dell latitude e6540

"Hi @ Sunny Singh

Here’s a link to all the drivers for your laptop.

Select the operating system and then scroll down to find the drivers. You may have to click on a Show All downloads box to find the ones you want.

You need to go into Device Manager in your laptop and check what make and model Bluetooth adapter is installed in your laptop as there are two different drivers available.

They are either a Dell Wireless 1707/1506/1601 WiFi/Bluetooth Driver or an Intel 6235 Bluetooth Application"
