From
defs.h
in
wpa_supplicant
.
These enumeration values are used to indicate the current wpa_supplicant
state. This is more fine-grained than most users will be interested in.
In general, it is better to use
NetworkInfo.State
.
Note, the order of these enum constants must match the numerical values of the
state constants in
defs.h
in
wpa_supplicant
.

Association completed.
This state is entered when the driver reports that association has been successfully completed with an AP. If IEEE 802.1X is used (with or without WPA/WPA2), wpa_supplicant remains in this state until the IEEE 802.1X/EAPOL authentication has been completed.
Trying to associate with a BSS/SSID.
This state is entered when wpa_supplicant has found a suitable BSS to associate with and the driver is configured to try to associate with this BSS in ap_scan=1 mode. When using ap_scan=2 mode, this state is entered when the driver is configured to try to associate with a network using the configured SSID and security policy.
Trying to authenticate with a BSS/SSID
This state is entered when wpa_supplicant has found a suitable BSS to authenticate with and the driver is configured to try to authenticate with this BSS.
All authentication completed.
This state is entered when the full authentication process is completed. In case of WPA2, this happens when the 4-Way Handshake is successfully completed. With WPA, this state is entered after the Group Key Handshake; with IEEE 802.1X (non-WPA) connection is completed after dynamic keys are received (or if not used, after the EAP authentication has been completed). With static WEP keys and plaintext connections, this state is entered when an association has been completed.
This state indicates that the supplicant has completed its processing for the association phase and that data connection is fully configured. Note, however, that there may not be any IP address associated with the connection yet. Typically, a DHCP request needs to be sent at this point to obtain an address.
This state indicates that client is not associated, but is likely to start looking for an access point. This state is entered when a connection is lost.
An Android-added state that is reported when a client issues an explicit DISCONNECT command. In such a case, the supplicant is not only dissociated from the current access point (as for the DISCONNECTED state above), but it also does not attempt to connect to any access point until a RECONNECT or REASSOCIATE command is issued by the client.
WPA 4-Way Key Handshake in progress.
This state is entered when WPA/WPA2 4-Way Handshake is started. In case of WPA-PSK, this happens when receiving the first EAPOL-Key frame after association. In case of WPA-EAP, this state is entered when the IEEE 802.1X/EAPOL authentication has been completed.
WPA Group Key Handshake in progress.
This state is entered when 4-Way Key Handshake has been completed (i.e., when the supplicant sends out message 4/4) and when Group Key rekeying is started by the AP (i.e., when supplicant receives message 1/2).
Inactive state (wpa_supplicant disabled).
This state is entered if there are no enabled networks in the configuration. wpa_supplicant is not trying to associate with a new network and external interaction (e.g., ctrl_iface call to add or enable a network) is needed to start association.
Interface is disabled
This state is entered if the network interface is disabled. wpa_supplicant refuses any new operations that would use the radio until the interface has been enabled.
A pseudo-state that should normally never be seen.
Scanning for a network.
This state is entered when wpa_supplicant starts scanning for a network.
No connection to wpa_supplicant.
This is an additional pseudo-state to handle the case where wpa_supplicant is not running and/or we have not been able to establish a connection to it.
Returns
true
if the supplicant state is valid and
false
otherwise.
