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 logi‐
	      cal OR. Also, setting an empty string "" pattern will match any device found.

       Usage  > pattern [value]

   auto-connect
       Set/Get auto-connect filter.

       Connect to discovered devices automatically if pattern filter has been set and it matches the device address or	name
       and the device is connectable.

       Usage  > auto-connect [on/off]

   clear
       Clears discovery filter.

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