command will be sent to the first available Bluetooth device.
COMMANDS¶
- dev
- Display local devices
- inq
- Inquire remote devices. For each discovered device,
Bluetooth device address, clock offset and class are printed.
- scan
- Inquire remote devices. For each discovered device, device
name are printed.
- name <bdaddr>
- Print device name of remote device with Bluetooth address
bdaddr.
- info <bdaddr>
- Print device name, version and supported features of remote
device with Bluetooth address bdaddr.
- spinq
- Start periodic inquiry process. No inquiry results are
printed.
- epinq

- cmd <ogf> <ocf> [parameters]
- Submit an arbitrary HCI command to local device.
ogf, ocf and parameters are hexadecimal bytes.
- con
- Display active baseband connections
- cc [--role=m|s] [--pkt-type=<ptype>]
<bdaddr>
- Create baseband connection to remote device with Bluetooth
address bdaddr. Option --pkt-type specifies a list of
allowed packet types. <ptype> is a comma-separated list of
packet types, where the possible packet types are DM1, DM3,
DM5, DH1, DH3, DH5, HV1, HV2,
HV3. Default is to allow all packet types. Option --role can
have value m (do not allow role switch, stay master) or s
(allow role switch, become slave if the peer asks to become master).
Default is m.
- dc <bdaddr> [reason]

HCI error codes. Default is 19 for user ended connections. The
value must be given in decimal.
- sr <bdaddr> <role>
- Switch role for the baseband connection from the remote

- rssi <bdaddr>
- Display received signal strength information for the
connection to the device with Bluetooth address bdaddr.
- lq <bdaddr>
- Display link quality for the connection to the device with
Bluetooth address bdaddr.
- tpl <bdaddr> [type]
- Display transmit power level for the connection to the
device with Bluetooth address bdaddr. The type can be 0 for
the current transmit power level (which is default) or 1 for the
maximum transmit power level.
- afh <bdaddr>
- Display AFH channel map for the connection to the device
with Bluetooth address bdaddr.
- lp <bdaddr> [value]
- With no value, displays link policy settings for the
connection to the device with Bluetooth address bdaddr. If
value is given, sets the link policy settings for that connection
to value. Possible values are RSWITCH, HOLD, SNIFF and PARK.
- lst <bdaddr> [value]
- With no value, displays link supervision timeout for
the connection to the device with Bluetooth address bdaddr. If
value is given, sets the link supervision timeout for that
connection to value slots, or to infinite if value is
0.
- auth <bdaddr>
- Request authentication for the device with Bluetooth
address bdaddr.
- enc <bdaddr> [encrypt enable]
- Enable or disable the encryption for the device with
Bluetooth address bdaddr.
- key <bdaddr>
- Change the connection link key for the device with
Bluetooth address bdaddr.
- clkoff <bdaddr>
- Read the clock offset for the device with Bluetooth address
bdaddr.
