I'm not sure I've understood what you describe as an issue here.. The eloop pselect calls are expected to time out if there are no pending events for the process. > What is really interesting is that a kill -1 on the wpa_supplicant > process determines a reconfiguration and the and the scanning process > is started (http://pastebin.com/QmmHTsmV).

This logs seems to show expected wpa_supplicant behavior.. If you want to scan for networks on Android, you'll need something to issue the scan command. Normally, this would be the Wi-Fi framework. Since you are running wpa_supplicant manually with custom configuration, Wi-Fi framework may not be able to support such a case. > > P.S.: Just for reference, I also attach the wpa_supplicant messages > > from a successful authentication (when wpa_supplicant is used > > automatically by the Android framework): http://pastebin.com/mbMXc2ie And this one is showing the Android framework requesting a scan and wpa_supplicant executing it. -- Jouni Malinen PGP id EFC895FA _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
