\subsection ctrl_iface_P2P_FIND P2P_FIND
Start P2P device discovery. Optional parameter can be used to specify
the duration for the discovery in seconds (e.g., "P2P_FIND 5"). If the
duration is not specified, discovery will be started for indefinite
time, i.e., until it is terminated by P2P_STOP_FIND or P2P_CONNECT (to
start group formation with a discovered peer).
The default search type is to first run a full scan of all channels
and then continue scanning only social channels (1, 6, 11). This
behavior can be changed by specifying a different search type: social
(e.g., "P2P_FIND 5 type=social") will skip the initial full scan and
only search social channels; progressive (e.g., "P2P_FIND
type=progressive") starts with a full scan and then searches
progressively through all channels one channel at the time with the
social channel scans. Progressive device discovery can be used to find
new groups (and groups that were not found during the initial scan,
e.g., due to the GO being asleep) over time without adding
considerable extra delay for every Search state round.
\subsection ctrl_iface_P2P_STOP_FIND P2P_STOP_FIND
Stop ongoing P2P device discovery or other operation (connect, listen
mode).
\subsection ctrl_iface_P2P_CONNECT P2P_CONNECT
Start P2P group formation with a discovered P2P peer. This includes
group owner negotiation, group interface setup, provisioning, and
establishing data connection.
P2P_CONNECT <peer device address> <pbc|pin|PIN#>
[label|display|keypad] [persistent] [join|auth] [go_intent=<0..15>]
Start P2P group formation with a discovered P2P peer. This includes
optional group owner negotiation, group interface setup, provisioning,
and establishing data connection.
The <pbc|pin|PIN#> parameter specifies the WPS provisioning
method. "pbc" string starts pushbutton method, "pin" string start PIN
method using an automatically generated PIN (which will be returned as
the command return code), PIN# means that a pre-selected PIN can be
used (e.g., 12345670). [label|display|keypad] is used with PIN method
to specify which PIN is used (label=PIN from local label,
display=dynamically generated random PIN from local display,
keypad=PIN entered from peer device label or display). "persistent"
parameter can be used to request a persistent group to be formed.
"join" indicates that this is a command to join an existing group as a
client. It skips the GO Negotiation part.
"auth" indicates that the WPS parameters are authorized for the peer
device without actually starting GO Negotiation (i.e., the peer is
expected to initiate GO Negotiation). This is mainly for testing
purposes.
The optional "go_intent" parameter can be used to override the default
GO Intent value.
\subsection ctrl_iface_P2P_LISTEN P2P_LISTEN
Start Listen-only state. Optional parameter can be used to specify the
duration for the Listen operation in seconds. This command may not
be of that much use during normal operations and is mainly designed
for testing. It can also be used to keep the device discoverable
without having to maintain a group.
\subsection ctrl_iface_P2P_GROUP_REMOVE P2P_GROUP_REMOVE
Terminate a P2P group. If a new virtual network interface was used for
the group, it will also be removed. The network interface name of the
group interface is used as a parameter for this command.
\subsection ctrl_iface_P2P_GROUP_ADD P2P_GROUP_ADD
Set up a P2P group owner manually (i.e., without group owner
negotiation with a specific peer). This is also known as autonomous
GO. Optional persistent=<network id> can be used to specify restart of
a persistent group.
\subsection ctrl_iface_P2P_PROV_DISC P2P_PROV_DISC
Send P2P provision discovery request to the specified peer. The
parameters for this command are the P2P device address of the peer and
the desired configuration method. For example, "P2P_PROV_DISC
02:01:02:03:04:05 display" would request the peer to display a PIN for
us and "P2P_PROV_DISC 02:01:02:03:04:05 keypad" would request the peer
to enter a PIN that we display.
\subsection ctrl_iface_P2P_GET_PASSPHRASE P2P_GET_PASSPHRASE
Get the passphrase for a group (only available when acting as a GO).
\subsection ctrl_iface_P2P_SERV_DISC_REQ P2P_SERV_DISC_REQ
Schedule a P2P service discovery request. The parameters for this
command are the device address of the peer device (or 00:00:00:00:00:00
for wildcard query that is sent to every discovered P2P peer that
supports service discovery) and P2P Service Query TLV(s) as hexdump.
For example, "P2P_SERV_DISC_REQ 00:00:00:00:00:00 02000001" schedules
a request for listing all supported service discovery protocols and
requests this to be sent to all discovered peers. The pending requests
are sent during device discovery (see \ref ctrl_iface_P2P_FIND).
This command returns an identifier for the pending query (e.g.,
"1f77628") that can be used to cancel the request. Directed requests
will be automatically removed when the specified peer has replied to
it.
\subsection ctrl_iface_P2P_SERV_DISC_CANCEL_REQ P2P_SERV_DISC_CANCEL_REQ
Cancel a pending P2P service discovery request. This command takes a
single parameter: identifier for the pending query (the value returned
by \ref ctrl_iface_P2P_SERV_DISC_REQ), e.g.,
"P2P_SERV_DISC_CANCEL_REQ 1f77628".
\subsection ctrl_iface_P2P_SERV_DISC_RESP P2P_SERV_DISC_RESP
Reply to a service discovery query. This command takes following
parameters: frequency in MHz, destination address, dialog token,
response TLV(s). The first three parameters are copied from the
request event. For example,
"P2P_SERV_DISC_RESP 2437 02:40:61:c2:f3:b7 1 0300000101".
\subsection ctrl_iface_P2P_SERVICE_UPDATE P2P_SERVICE_UPDATE
Indicate that local services have changed. This is used to increment
the P2P service indicator value so that peers know when previously
cached information may have changed.
\subsection ctrl_iface_P2P_SERV_DISC_EXTERNAL P2P_SERV_DISC_EXTERNAL
Configure external processing of P2P service requests: 0 (default) =
no external processing of requests (i.e., internal code will reject
each request), 1 = external processing of requests (external program
is responsible for replying to service discovery requests with
\ref ctrl_iface_P2P_SERV_DISC_RESP).
\subsection ctrl_iface_P2P_REJECT P2P_REJECT
Reject connection attempt from a peer (specified with a device
address). This is a mechanism to reject a pending GO Negotiation with
a peer and request to automatically block any further connection or
discovery of the peer.
\subsection ctrl_iface_P2P_INVITE P2P_INVITE
Invite a peer to join a group or to (re)start a persistent group.
\subsection ctrl_iface_P2P_PEER P2P_PEER
Fetch information about a discovered peer. This command takes in an
argument specifying which peer to select: P2P Device Address of the
peer, "FIRST" to indicate the first peer in the list, or "NEXT-<P2P
Device Address>" to indicate the entry following the specified peer
(to allow for iterating through the list).
\subsection ctrl_iface_P2P_EXT_LISTEN P2P_EXT_LISTEN
Enable/disable extended listen timing. Without parameters, this
command disables extended listen timing. When enabling the feature,
two parameters are used: availibility period and availability interval
(both in milliseconds and with range of 1-65535).
