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.
