FAQ

Check the configuration of the bluetooth stack. This hcid.conf file^[1] can be used as an example configuration file for the bluetooth stack.

Bluetooth devices on your computers must be in inquiry mode, i.e. they must be discoverable. You can check this with:

$ hciconfig

In the output must be a line like this:

UP RUNNING PSCAN ISCAN

If this is not the case (although it should be when you used the configuration file above), you can enable inquiry mode with:

$ hciconfig hciX iscan

where X is the number of the Bluetooth decive to configure (0 for the first)

Also check the bluetooth configuration of your mobile device: Is bluetooth enabled? Is your device allowed to set up connections with your computer?

If all this does not help, have a look at this problem discussion.

↑ On Ubuntu/Debian systems you can find the file hcid.conf in /etc/bluetooth/
