hciattach - attach serial devices via UART HCI to BlueZ stack
hciattach [OPTIONS] <tty>
<type|id> [speed] [flow] [sleep]
[bdaddr]
hciattach -1
hciattach(1) is used to attach a serial UART to the
Bluetooth stack as HCI transport interface.
- -i
- Send break
- -n
- Don't detach from controlling terminal.
- -p
- Print the PID when detaching.
- -t timeout
- Specify an initialization timeout. Default is 5 seconds.
- -s speed
- Specify an initial speed instead of the hardware default.
- -l
- List all available configurations.
- -r
- Set the HCI device into raw mode. The kernel and bluetooth daemon will
ignore it.
- -h,
--help
- Show help options
- show
- This specifies the serial device to attach. A leading /dev can be omitted.
Examples: /dev/ttyS1 ttyS2
- type|id
- The type or id of the Bluetooth device that is to be
attached, i.e. vendor or other device specific identifier. Currently
supported types are

- speed
- The speed specifies the UART speed to use. Baudrates higher than
115200bps require vendor specific initializations that are not implemented
for all types of devices. In general the following speeds are supported:
Supported vendor devices are automatically initialised to
their respective best settings.
| 9600 |
| 19200 |
| 38400 |
| 57600 |
| 115200 |
| 230400 |
| 460800 |
| 921600 |
- flow
- If the flow is appended to the list of options then hardware flow
control is forced on the serial link (CRTSCTS). All above mentioned
device types have flow set by default. To force no flow control use
noflow instead.
- sleep|nosleep
- Enables hardware specific power management feature. If sleep is
appended to the list of options then this feature is enabled. To disable
this feature use nosleep instead. All above mentioned device types
have nosleep set by default.
Note: This option will only be valid for hardware which
support hardware specific power management enable option from host.
- bdaddr
- The bdaddr specifies the Bluetooth Address to use. Some devices (like the
STLC2500) do not store the Bluetooth address in hardware memory. Instead
it must be uploaded during the initialization process. If this argument is
specified, then the address will be used to initialize the device.
Otherwise, a default address will be used.
