sdpd -- Bluetooth Service Discovery Protocol daemon SYNOPSIS
sdpd [-dh] [-c path] [-g group] [-u user] DESCRIPTION
The sdpd daemon keeps track of the Bluetooth services registered on the host and responds to Service Discovery inquiries from the remote Bluetooth devices. In order to use any service remote Bluetooth device need to send Service Search and Service Attribute or Service Search Attribute request over Bluetooth L2CAP connection on SDP PSM (0x0001). The sdpd daemon will try to find matching Service Record in its Service Database and will send appropriate response back. The remote device then will process the response, extract all required information and will make a sep- arate connection in order to use the service. Bluetooth applications, running on the host, register services with the local sdpd daemon. Operation like service registration, service removal and service change are performed over the control socket. It is possible to query entire content of the sdpd Service Database with sdpcontrol(8) by issuing browse command on the control socket. The command line options are as follows: -d Do not detach from the controlling terminal. -c path Specify path to the control socket. The default path is /var/run/sdp. -g group Specifies the group the sdpd should run as after it initializes. The value specified may be either a group name or a numeric group ID. This only works if sdpd was started as root. The default group name is ``nobody''. -h Display usage message and exit. -u user Specifies the user the sdpd should run as after it initializes. The value specified may be either a user name or a numeric user ID. This only works if sdpd was started as root. The default user name is ``nobody''. CAVEAT
The sdpd daemon will listen for incoming L2CAP connections on a wildcard BD_ADDR. In case of multiple Bluetooth devices connected to the same host it is possible to specify which services should be ``bound'' to which Blue- tooth device. Such assignment should be done at service registration time. Requests to register, remove or change service can only be made via the control socket. The sdpd daemon will check peer's credentials and will only accept the request if the application has the same effective user ID as the ``root'' user ID. The sdpd daemon does not check for duplicated Service Records. It only performs minimal checking on the service data sent in the Service Register request. It is assumed that application must obtain all required resources such as RFCOMM channels etc., before registering the service. FILES

sdpquery -- Service Discovery Protocol query utility SYNOPSIS
sdpquery [-NRX] [-d device] -a address command [parameters ...] sdpquery [-NRX] [-c path] -l command [parameters ...] DESCRIPTION
The sdpquery utility attempts to query the specified Service Discovery Protocol (SDP) server. Remote SDP servers are identified by their address. Connection to the local SDP server is made via the control socket. The sdpquery utility retrieves complete Service Records as directed and prints each record's attribute ID/value list to standard output and error messages to standard error. The options are as follows: -a address Connect to the remote device with the specified address. The address can be specified as BD_ADDR or a name. If a name was spec- ified, the sdpquery utility attempts to resolve the name via bt_gethostbyname(3). If no remote address is given, sdpquery attempts to contact a local SDP server via the control socket. -c path Specify path to the control socket. The default path is /var/run/sdp. -d device Connect from the local device with the specified address. The device can be specified by BD_ADDR or device name. See btconfig(8) for a list of devices available. If no device is specified, the sdpquery utility will use the best available. -l Query the local SDP server via the control socket. -N Additionally display numerical values. -R Display service attributes in raw (uninterpreted) format. -X Display service attribute values in hex. The currently supported commands in sdpquery are: Browse [group] Browse for services. The group parameter is the UUID of the group to browse. If omitted, the "Public Browse Group" is used. Record handle [handle...] Retrieve the Service Record with the given handle. Multiple handles can be given. Search uuid [uuid...] Search for records matching the list of UUIDs which can be given in numerical form, or the following aliases are known: A2DP Advanced Audio Distribution Profile BNEP Bluetooth Network Encapsulation Protocol CIP Common ISDN Access Service CTP Cordless Telephony Service DUN Dialup Networking Service FAX Fax Service FTRN File Transfer Service GN Group ad-hoc Network Service HID Human Interface Device Service HF Handsfree Service HSET Headset Service L2CAP Logical Link Control and Adaptation Protocol LAN LAN Access Using PPP Service NAP Network Access Point Service OBEX Object Exchange Protocol OPUSH Object Push Service PANU Personal Area Networking User Service PNP Plug'n'Play Information Service RFCOMM RFCOMM Protocol SDP Service Discovery Protocol SP Serial Port Service SYNC IrMC Sync Client Service Note that in order for a record to match, it must contain all the UUIDs in the ServiceSearchPattern and the maximum number is 12. EXIT STATUS
The sdpquery utility exits 0 on success, and >0 if an error occurs. SEE ALSO
