hciconfig -h

hciconfig [-a]

hciconfig [-a] <hciX> [command [command parameters]]

hciconfig is used to configure Bluetooth devices. <hciX> is the name of a Bluetooth device installed in the system. If <hciX> is not given, hciconfig prints name and basic information about all the Bluetooth devices installed in the system. If <hciX> is given but no command is given, it prints basic information on device <hciX> only. Basic information is interface type, BD address, ACL MTU, SCO MTU, flags (up, init, running, raw, page scan enabled, inquiry scan enabled, inquiry, authentication enabled, encryption enabled).

With no win:int, prints inquiry scan window and interval. Otherwise, sets inquiry scan window to win slots and inquiry scan interval to int slots.

pageparms [win:int]

With no win:int, prints page scan window and interval. Otherwise, sets page scan window to win slots and page scan interval to int slots.

pageto [to]

With no to, prints page timeout. Otherwise, sets page timeout to to slots.

afhmode [mode]

With no mode, prints out the current AFH mode. Otherwise, sets AFH mode to mode.

aclmtu <mtu:pkt>

Sets ACL MTU to to mtu bytes and ACL buffer size to pkt packets.

scomtu <mtu:pkt>

Sets SCO MTU to to mtu bytes and SCO buffer size to pkt packets.

putkey <bdaddr>

This command stores the link key for bdaddr on the device.

delkey <bdaddr>

This command deletes the stored link key for bdaddr from the device.

commands

Display supported commands.

features

lm [mode]

With no mode , prints link mode. MASTER or SLAVE mean, respectively, to ask to become master or to remain slave when a connection request comes in. The additional keyword ACCEPT means that baseband connections will be accepted even if there are no listening AF_BLUETOOTH sockets. mode is NONE or a comma-separated list of keywords, where possible keywords are MASTER and ACCEPT . NONE sets link policy to the default behaviour of remaining slave and not accepting baseband connections when there are no listening AF_BLUETOOTH sockets. If MASTER is present, the device will ask to become master if a connection request comes in. If ACCEPT is present, the device will accept baseband connections even when there are no listening AF_BLUETOOTH sockets.
