How can I find out what version of bluetooth my laptop supports?
Is there a place in Windows I can see this? I want to know if it supports bluetooth 3, and the specs are difficult to find!
First, go to Control Panel and open "Device Manager" (or just search for it from the Start Menu). From there, click the dropdown next to Bluetooth and locate the Bluetooth adapter for your device. (It will be the item that does not have "Enumerator" in its name.) In my case, it's "Bluetooth USB Module":
Right-click this item and select "Properties". Then go to the "Advanced" tab and note the LMP (link management protocol) version displayed for the device:
The LMP versions correspond to Bluetooth versions as follows:
- LMP 0.x - Bluetooth 1.0b
- LMP 1.x - Bluetooth 1.1
- LMP 2.x - Bluetooth 1.2
- LMP 3.x - Bluetooth 2.0 + EDR
- LMP 4.x - Bluetooth 2.1 + EDR
- LMP 5.x - Bluetooth 3.0 + HS
- LMP 6.x - Bluetooth 4.0
- LMP 7.x - Bluetooth 4.1
- LMP 8.x - Bluetooth 4.2
- LMP 9.x - Bluetooth 5.0

Right click on "My Computer" (desktop) -> Device manager -> expand to see the bluetooth driver. In my case it is "Bluetooth v3.0".
Go to Device Manager > Bluetooth > Right Click on {your_bluetooth_device} > Properties > Details tab > Bluetooth Radio LMP version > Value field.
In my case it was 0A (HEX) -> 10 (decimal) which means Bluetooth 5.1 if you match against this Link Manager Protocol Versions list.
