33 .Nd Bluetooth Service Discovery Protocol daemon
43 daemon keeps track of the Bluetooth services registered on the host
44 and responds to Service Discovery inquiries from the remote Bluetooth devices.
46 In order to use any service remote Bluetooth device need to send Service
47 Search and Service Attribute or Service Search Attribute request over
48 Bluetooth L2CAP connection on SDP PSM (0x0001).
51 daemon will try to find matching Service Record in its Service Database
52 and will send appropriate response back.
53 The remote device then will process the response, extract all required
54 information and will make a separate connection in order to use the service.
56 Bluetooth applications, running on the host, register services with
60 Operation like service registration, service removal and service change are
61 performed over the control socket.
62 It is possible to query entire content of the
68 command on the control socket.
70 The command line options are as follows:
71 .Bl -tag -width indent
73 Do not detach from the controlling terminal.
75 Specify path to the control socket.
79 Specifies the group the
81 should run as after it initializes.
82 The value specified may be either a group name or a numeric group ID.
86 The default group name is
89 Display usage message and exit.
91 Specifies the user the
93 should run as after it initializes.
94 The value specified may be either a user name or a numeric user ID.
98 The default user name is
105 will listen for incoming L2CAP connections on a wildcard BD_ADDR.
107 In case of multiple Bluetooth devices connected to the same host it is
108 possible to specify which services should be
110 to which Bluetooth device.
111 Such assignment should be done at service registration time.
113 Requests to register, remove or change service can only be made via the
117 daemon will check peer's credentials and will only accept the request if
118 the application has the same effective user ID as the
124 daemon does not check for duplicated Service Records.
125 It only performs minimal checking on the service data sent in the Service
127 It is assumed that application must obtain all required resources such
128 as RFCOMM channels etc., before registering the service.
