jessie moved my WiFi cheese

Since I last brought up wifi on a BBB rev c apparently a new way has become standard for configuring wifi. connmanctl With a couple BBB rev C that I have run Wheezy on with Edimax USB wifi dongles receiving a DHCP ip v4 address after modifying /etc/network/interfaces. I'm trying to flash a jessie image on those same rev C BBBs and dongles and bring up wifi. I've tried all of these three images

.

bone-debian-8.4-lxqt-4gb-armhf-2016-05-13-4gb.img

and

BBB-blank-debian-8.5-lxqt-4gb-armhf-2016-06-19-4gb.img

and

bone-debian-8.5-iot-armhf-2016-06-19-4gb.img

Am I using the correct image? Did I miss some RTFM?

I just uncomment the flasher line in uEnv.txt and boot. No messing with holding buttons down anymore right? Seems to work.

With both images I get the following running connmanctl Which doesn't look like what I've seen in threads here in the Google Groups BBB forum.

A quick ifconfig first

I noticed a syntax on this connmanctl cheat sheet on github. I invoked the wifi scan differently. Previously in interactive mode the wifi scan came back immediately without receiving "Scan completed for wifi"

These comments / issues found on that cheat sheet didn't inspire confidence.,

Comments / Issues
WiFi driver + connman-1.17 + beaglebone appears to be buggy with connmanctl disable/enable
Connmanctl connect seems buggy, potential it calls enable?

root@beaglebone:~# time connmanctl scan wifi
Error /net/connman/technology/wifi: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

I found in a thread "connman issues on latest Debian 8.4 release?" similar problems. I tried turning tethering off and connmanctl reported "Scan completed for wifi" this time, but still didn't report any access points. This thread reports the user had wifi connection on 8.3. If I find an image I'll try it and report back.

I'm not understanding that the wifi is having trouble in debian 8.4. Don't a majority of users enable wifi? I wonder how many folks per month flash their BBB with a new image?
