BTATTACH(8)

NAME
btattach - attach serial lines as Bluetooth HCI interfaces

SYNOPSIS
btattach [-dFfoPp] [-i speed] [type] tty speed
btattach -t [-dFfoPp] tty

DESCRIPTION
btattach is used to assign a tty line to a Bluetooth Host Controller Interface using the btuart(4) or bcsp(4) line disciplines, and can optionally initialize the line for a given device type before activating the line discipline.

Supported types are:
bcm2035
    Broadcom BCM2035
bcsp
    Generic BCSP (BlueCore Serial Protocol)
bgb2xx
    Philips BGB2xx module
btuart
    Generic UART (this is the default)
csr Cambridge Silicon Radio Casira serial adapter, or Brainboxes serial dongle (BL642)
ericsson
    Ericsson based modules
digi
    Digianswer based cards
st  ST Microelectronics minikits based on STLC2410/STLC2415
stlc2500
    ST Microelectronics minikits based on STLC2500
swave
    Silicon Wave kits
texas
    Texas Instruments modules
unistone
    Infineon UniStone (PBA31308) modules

When the line discipline is activated, btattach detaches and sleeps until it receives a SIGHUP.

The command line options are as follows:

-d  debug mode. print initialization IO and do not detach.

-F  Disable flow control.

-f  Enable flow control.

-i speed
    Specify an alternate speed for the Bluetooth module to use during the initialization phase.

-o  Enable odd parity.

-P  Disable parity.

-p  Enable parity (even parity).

-t  Test mode.

Only the super-user may attach a Bluetooth HCI interface.

Test mode tries to guess the speed using the received link-establish packet from HCI, or btuart(4), if there is no response.
