hcid8

Usage

Overview

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.

Options

-n

Don't fork to run daemon in background.

-d

Enable debug information output.

-s

Enable internal SDP server.

-m mtu-size

Use specific MTU size for SDP server.

-f config-file

Use alternate configuration file instead of /etc/bluetooth/hcid.conf
