Device Discovery
p2p_find [timeout in seconds] [type=<social|progressive>] \
- [dev_id=<addr>] [delay=<search delay in ms>]
+ [dev_id=<addr>] [dev_type=<device type>] \
+ [delay=<search delay in ms>]
The default behavior is to run a single full scan in the beginning and
then scan only social channels. type=social will scan only social
delay to be used between search iterations (e.g., to free up radio
resources for concurrent operations).
+The optional dev_type option can be used to specify a single device type
+(primary or secondary) to search for, e.g.,
+"p2p_find dev_type=1-0050F204-1".

p2p_listen [timeout in seconds]

- [go_intent=<0..15>] [freq=<in MHz>] [ht40] [provdisc]
+ [go_intent=<0..15>] [freq=<in MHz>] [ht40] [vht] [provdisc]
Start P2P group formation with a discovered P2P peer. This includes
optional group owner negotiation, group interface setup, provisioning,
P2P implementations that require this to allow the user to accept the
connection.
-p2p_group_add [persistent|persistent=<network id>] [freq=<freq in MHz>] [ht40]
+p2p_group_add [persistent|persistent=<network id>] [freq=<freq in MHz>]
+ [ht40] [vht]
Set up a P2P group owner manually (i.e., without group owner
negotiation with a specific peer). This is also known as autonomous
step. If the WPS provisioning step has been completed, the group is not
terminated.
+p2p_remove_client <peer's P2P Device Address|iface=<interface address>>
+
+This command can be used to remove the specified client from all groups
+(operating and persistent) from the local GO. Note that the peer device
+can rejoin the group if it is in possession of a valid key. See p2p_set
+per_sta_psk command below for more details on how the peer can be
+removed securely.

Service Discovery
p2p_serv_disc_req
peers (note: this can result in long response frames). The pending
requests are sent during device discovery (see p2p_find).
-Only a single pending wildcard query is supported, but there can be
-multiple pending peer device specific queries (each will be sent in
-sequence whenever the peer is found).
+There can be multiple pending peer device specific queries (each will be
+sent in sequence whenever the peer is found).
This command returns an identifier for the pending query (e.g.,
"1f77628") that can be used to cancel the request. Directed requests
Invitation
p2p_invite [persistent=<network id>|group=<group ifname>] [peer=address]
- [go_dev_addr=address] [freq=<freq in MHz>] [ht40]
+ [go_dev_addr=address] [freq=<freq in MHz>] [ht40] [vht]
+ [pref=<MHz>]
Invite a peer to join a group (e.g., group=wlan1) or to reinvoke a
persistent group (e.g., persistent=4). If the peer device is the GO of
used to override the GO device address for Invitation Request should
it be not known for some reason (this should not be needed in most
cases). When reinvoking a persistent group, the GO device can specify
-the frequency for the group with the freq parameter.
+the frequency for the group with the freq parameter. When reinvoking a
+persistent group, the P2P client device can use freq parameter to force
+a specific operating channel (or invitation failure if GO rejects that)
+or pref parameter to request a specific channel (while allowing GO to
+select to use another channel, if needed).
Group Operations
Send a P2P Presence Request to the GO (this is only available when
acting as a P2P client). If no duration/interval pairs are given, the
request indicates that this client has no special needs for GO
-presence. the first parameter pair gives the preferred duration and
+presence. The first parameter pair gives the preferred duration and
interval values in microseconds. If the second pair is included, that
-indicates which value would be acceptable.
+indicates which value would be acceptable. This command returns OK
+immediately and the response from the GO is indicated in a
+P2P-PRESENCE-RESPONSE event message.
Parameters
(DIRECT-<two random characters>). For example, postfix of "-testing"
could result in the SSID becoming DIRECT-ab-testing.
+p2p_set per_sta_psk <0/1>
+
+Disabled(default)/enables use of per-client PSK in the P2P groups. This
+can be used to request GO to assign a unique PSK for each client during
+WPS provisioning. When enabled, this allow clients to be removed from
+the group securily with p2p_remove_client command since that client's
+PSK is removed at the same time to prevent it from connecting back using
+the old PSK. When per-client PSK is not used, the client can still be
+disconnected, but it will be able to re-join the group since the PSK it
+learned previously is still valid. It should be noted that the default
+passphrase on the GO that is normally used to allow legacy stations to
+connect through manual configuration does not change here, so if that is
+shared, devices with knowledge of that passphrase can still connect.
+
set <field> <value>
Set global configuration parameters which may also affect P2P
Set country code (this is included in some P2P messages).
+set p2p_search_delay <delay>
+
+Set p2p_search_delay which adds extra delay in milliseconds between
+concurrent search iterations to make p2p_find friendlier to concurrent
+operations by avoiding it from taking 100% of radio resources. The
+default value is 500 ms.
