Có một số nguyên nhân tại sao bạn không thể kết nối đến một thiết bị Bluetooth, như điện thoại hoặc tai nghe.
Some Bluetooth devices block connections by default, or require you to change a setting to allow connections to be made. Make sure that your device is set up to allow connections.
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.
Many computers do not have Bluetooth adapters. You can buy an adapter if you want to use Bluetooth.
