I cannot connect my Bluetooth device

有些蓝牙设备会默认拦截连接，或要求您更改设置才能允许建立连接。确保将您的设备设置为允许连接。

Your Bluetooth adapter or dongle may not have been recognized by the computer. This could be because drivers for the adapter are not installed. Some Bluetooth adapters are not supported on Linux, so you may not be able to get the right drivers for them. In this case, you will probably have to get a different Bluetooth adapter.

Make sure that your Bluetooth adapter is switched on. Open the Bluetooth panel and check that it is not disabled.

Check that Bluetooth is turned on on the device you are trying to connect to, and that it is discoverable or visible. For example, if you are trying to connect to a phone, make sure that it is not in airplane mode.

很多计算机都不具备蓝牙适配器。如果您想要使用蓝牙，可以购买适配器。
