NAME

       bluetoothctl-scan - Scan Submenu

SYNOPSIS

       bluetoothctl [--options] [scan.commands]

SCAN COMMANDS

   uuids
       Set/Get UUIDs filter.

       Usage  # uuids [all/uuid1 uuid2 ...]

   rssi
       Set/Get RSSI filter, and clears pathloss.

       This sets the minimum rssi value for reporting device advertisements.

       The value is in dBm.

       If one or more discovery filters have been set, the RSSI delta-threshold imposed by starting discovery by
       default will not be applied.

       Usage  # rssi [rssi]

       Example
              # rssi -60

   pathloss
       Set/Get Pathloss filter, and clears RSSI.

       This sets the maximum pathloss value for reporting device advertisements.

       The value is in dB.

       If one or more discovery filters have been set, the RSSI delta-threshold imposed by starting discovery by
       default will not be applied.

       Usage  # pathloss [pathloss]

       Example
              # pathloss 4

   transport
       Set/Get transport filter.

       Transport parameter determines the type of scan.

       The default is auto.

       Possible values:

       • "auto": interleaved scan

       • "bredr": BR/EDR inquiry

       • "le": LE scan only

       If   "le"   or   "bredr"   Transport   is   requested   and   the   controller  doesn't  support  it,  an
       org.bluez.Error.Failed error will be returned.

       If "auto" transport is requested, the scan will use LE, BREDR, or both,  depending  on  what's  currently
       enabled on the controller.

       Usage  # transport [auto/bredr/le]

   duplicate-data
       Set/Get duplicate data filter.

       Disables duplicate detection of advertisement data.

       When enabled, PropertiesChanged signals will be generated for ManufacturerData and ServiceData every time
       they are discovered.

       Usage  # duplicate-data [on/off]

   discoverable
       Set/Get discoverable filter.

       Makes the adapter discoverable while discovering.

       If the adapter is already discoverable, setting this filter won't have any effect.

       Usage  # discoverable [on/off]

   pattern
       Set/Get pattern filter.

       Discover devices where the pattern matches either the prefix of the address or the device name, which  is
       a convenient way to limit the number of device objects created during a discovery.

       When set, it disregards device discoverable flags.

       Note   The pattern matching is ignored if there are other clients that don't set any pattern, as it works
              as a logical OR. Also, setting an empty string "" pattern will match any device found.

       Usage  # pattern [value]

   clear
       Clears discovery filter.

       Usage  # clear [uuids/rssi/pathloss/transport/duplicate-data/discoverable/pattern]
