9 hcitool [-h]
10 hcitool [-i <hciX>] [command [command parameters]]
11
14 hcitool is used to configure Bluetooth connections and send some spe‐
15 cial command to Bluetooth devices. If no command is given, or if the
16 option -h is used, hcitool prints some usage information and exits.
17
19 -h Gives a list of possible commands
20 -i <hciX>
22 The command is applied to device hciX , which must be the name
23 of an installed Bluetooth device. If not specified, the command
24 will be sent to the first available Bluetooth device.
25
27 dev Display local devices
28 inq Inquire remote devices. For each discovered device, Bluetooth
30 device address, clock offset and class are printed.
31 scan Inquire remote devices. For each discovered device, device name
33 are printed.
34 name <bdaddr>
36 Print device name of remote device with Bluetooth address
37 bdaddr.
38 info <bdaddr>
40 Print device name, version and supported features of remote
41 device with Bluetooth address bdaddr.
42 spinq Start periodic inquiry process. No inquiry results are printed.
44 epinq Exit periodic inquiry process.
46 cmd <ogf> <ocf> [parameters]
48 Submit an arbitrary HCI command to local device. ogf, ocf and
49 parameters are hexadecimal bytes.
50 con Display active baseband connections
52 cc [--role=m|s] [--pkt-type=<ptype>] <bdaddr>
54 Create baseband connection to remote device with Bluetooth
55 address bdaddr. Option --pkt-type specifies a list of allowed
56 packet types. <ptype> is a comma-separated list of packet
57 types, where the possible packet types are DM1, DM3, DM5, DH1,
58 DH3, DH5, HV1, HV2, HV3. Default is to allow all packet types.
59 Option --role can have value m (do not allow role switch, stay
60 master) or s (allow role switch, become slave if the peer asks
61 to become master). Default is m.
62 dc <bdaddr> [reason]
64 Delete baseband connection from remote device with Bluetooth
65 address bdaddr. The reason can be one of the Bluetooth HCI
66 error codes. Default is 19 for user ended connections. The value
67 must be given in decimal.
68 sr <bdaddr> <role>
70 Switch role for the baseband connection from the remote device
71 to master or slave.
72 cpt <bdaddr> <packet types>
74 Change packet types for baseband connection to device with Blue‐
75 tooth address bdaddr. packet types is a comma-separated list of
76 packet types, where the possible packet types are DM1, DM3, DM5,
77 DH1, DH3, DH5, HV1, HV2, HV3.

84 Display link quality for the connection to the device with Blue‐
85 tooth address bdaddr.
86 tpl <bdaddr> [type]
88 Display transmit power level for the connection to the device
89 with Bluetooth address bdaddr. The type can be 0 for the cur‐
90 rent transmit power level (which is default) or 1 for the maxi‐
91 mum transmit power level.
92 afh <bdaddr>
94 Display AFH channel map for the connection to the device with
95 Bluetooth address bdaddr.
96 lp <bdaddr> [value]
98 With no value, displays link policy settings for the connection
99 to the device with Bluetooth address bdaddr. If value is given,
100 sets the link policy settings for that connection to value.
101 Possible values are RSWITCH, HOLD, SNIFF and PARK.
102 lst <bdaddr> [value]
104 With no value, displays link supervision timeout for the connec‐
105 tion to the device with Bluetooth address bdaddr. If value is
106 given, sets the link supervision timeout for that connection to
107 value slots, or to infinite if value is 0.
108 auth <bdaddr>
110 Request authentication for the device with Bluetooth address
111 bdaddr.
112 enc <bdaddr> [encrypt enable]
