蓝牙^(Bluetooth)曾经是一种新奇的尖端无线技术。对于我们这些记得过去在非常愚蠢的手机上使用 IR 端口的人来说，蓝牙^(Bluetooth)似乎是一种巫术。今天，几乎所有东西都使用 BT，它已成为我们生活中可靠、无缝的一部分。

这在很大程度上要归功于对原始版本的不断改进。在撰写本文时，蓝牙 5.1^{(Bluetooth 5.1)}已经发布。

每个版本都带来了新的功能和改进。所有版本也都向后兼容，但通常您将受限于使用的最低 BT 版本硬件支持的功能。

换句话说，如果那个花哨的新 BT 鼠标支持超高效的电源使用，但您的笔记本电脑的 BT 版本不支持，那么您正在为一项您无法使用的功能付费。

虽然外围设备通常会在包装盒上粗体显示其蓝牙^(Bluetooth)编号，但要弄清楚内置适配器的版本可能会比较棘手。幸运的是，如果您不介意在菜单中挖掘一点，您可以直接从Windows 10中获取该信息。^{(Windows 10)}

从 Windows 10 获取蓝牙版本

您要做的第一件事是打开设备管理器^{(Device Manager)}。您可以通过打开开始菜单并搜索它来找到它。

打开设备管理器。^{(Open Device Manager. )}它应该看起来像这样。

现在，展开蓝牙^{(Bluetooth )}类别。

右键单击^{(Right-click)}有问题的 BT 适配器，然后单击Properties。

在“高级^(Advanced)”选项卡下，记下LMP编号。]现在，这些是 BT 版本号和它们的 LMP号。

• LMP 0 – 蓝牙 1.0b
• LMP 1 – 蓝牙 1.1
• LMP 2 – 蓝牙 1.2
• LMP 3 – 蓝牙 2.0 + EDR
• LMP 4 – 蓝牙 2.1 + EDR
• LMP 5 – 蓝牙 3.0 + HS
• LMP 6 – 蓝牙 4.0
• LMP 7 – 蓝牙 4.1
• LMP 8 – 蓝牙 4.2
• LMP 9 – 蓝牙 5

仅仅为了获得一个版本号就很费劲了，但现在至少您可以弄清楚您的计算机具有哪些功能！

How to Find Your Bluetooth Adapter Version in Windows 10

Bluetooth used to be a new, strange and cutting-edge wireless technology. For those of us who remember using the ІR port on out very dumb phones back in the day, Bluetooth seemed like witchcraft. Today almost everything uses BT and it’s become a reliable, sеamless part of oυr lives.

That’s largely thanks to the constant improvements that have been made to the original release. At the time of writing, Bluetooth 5.1 has been announced.

Each version brings with it new features and improvements. All versions are also backwards compatible, but in general you’ll be limited to the features supported by the lowest BT version hardware in use.

In other words, if that fancy new BT mouse supports hyper-efficient power use, but your laptop’s BT version does not, you’re paying for a feature you can’t use.

While peripherals will usually state their Bluetooth number boldy on the box, figuring out the version of your built-in adapter can be tricker. Luckily you can get that information directly out of Windows 10, if you don’t mind digging a little in the menus.

Getting Your Bluetooth Version From Windows 10

The first thing you want to do is open Device Manager. You can find it by opening the start menu and searching for it.

Open Device Manager. It should look like this.

Now, expand the Bluetooth category.

Right-click on the BT adapter in question and then click Properties.

Under the Advanced tab, make a note of the LMP number.]Now, these are the BT version numbers and the LMP numbers they go with.

• 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

That’s quite a trek just to get a version number, but now at least you can figure out which features your computer has onboard!
