sdpquery —
Service Discovery Protocol query utility
  
    | sdpquery | [ -NRX] [-ddevice]-aaddress command
      [parameters ...] | 
  
    | sdpquery | [ -NRX] [-cpath]-lcommand [parameters ...] | 
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:
  - -aaddress
- Connect to the remote device with the specified address. The address can
      be specified as BD_ADDR or a name. If a name was specified, the
      sdpqueryutility attempts to resolve the name via
      bt_gethostbyname(3).
      If no remote address is given,sdpqueryattempts
      to contact a local SDP server via the control socket.
- -cpath
- Specify path to the control socket. The default path is
      /var/run/sdp.
- -ddevice
- 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
      sdpqueryutility 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.
    
  
- Recordhandle [handle...]
- Retrieve the Service Record with the given handle.
      Multiple handles can be given.
    
  
- Searchuuid [uuid...]
- Search for records matching the list of UUIDs which can be given in
      numerical form, or the following aliases are known:
