About WPS on two interfaces of dual band

[annapurna bommakanti]

I run two hostapd process for each interface.
Though I have mentioned UUID in both of the hostapd configuration files,
I see that the stations are not associated. I do not see any PBC overlap.
Below is the trace:

=====>>>>>wpsStatus: 1
=====>>>>>wps_button_pushed
WPS: Checking active PBC sessions for overlap
WPS: Consider PBC session with 00:25:9c:9b:be:22

WPS: PBC walk time has expired
WPS: 0 active PBC session(s) found
WPS: Button pushed - PBC mode started (timeout=120)
