Ok, I'm prepared for the RTFM response but I could really use some
fast-tracking!
1) I have an embedded Linux system based on a yocto image. So I have connman
and wpa_supplicant.
2) From my reading to date I should use connman only and avoid the complexity
of wpa_supplicant.
3) I plan to support WiFi interfaces only....Enterprise and WPA (no open
networks)
Questions:
1) I noticed there is no /etc/connman/main.conf by default. I suppose if I
create that file it will configure connman provided my syntax is correct?
2) I'm clear how to use connmanctl interactive mode to make a connection but
I'm less clear on the process for my Qt application to perform this. I believe
it would simply be a connmanctl connect call when a user configures a WiFi
SSID. As connman persists over a reboot do I only issue the connect call when
a user re-configures and on reboot provided connman and wpa_supplicant services
are up the connection will attempt to re-establish?
3) I've noticed sometimes connman connections seem "In progress"...how can I
force a connman abort and "reset" to get ready for a new command? Anyway to do
this without restarting the connman service?
4) In my WPA, I'm a bit lost regarding how provisioning files work. When my
user enters appropriate information is there a command I can call to build a
provisioning file for the connection I've established? Does connman
automatically update files like /etc/wpa_supplicant.conf?
Thanks,
-Rich

connect command via connmanctl.
