hcid - Bluetooth Host Controller Interface Daemon

hcid [ -n ] [ -f config-file ]

This manual page documents briefly the hcid daemon, which manages all the Bluetooth devices. hcid itself does not accept many command-line options, as most of its configuration is done in the hcid.conf file, which has its own man page. hcid can also provide a number of services via the D-BUS message bus system.
