There are a number of reasons why you may not be able to connect to a
Bluetooth device, such as a phone or headset.
-
Connection blocked or untrusted
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.
-
Bluetooth hardware not recognized
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.
-
Adapter is not switched on
Make sure that your Bluetooth adapter is switched on. Open the
Bluetooth panel and check that it is not
disabled.
-
Device Bluetooth connection switched off
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.
-
No Bluetooth adapter in your computer
Many computers do not have Bluetooth adapters. You can buy an adapter
if you want to use Bluetooth.
