I am new to connman and I'm trying to get WiFi working. I previously had it somewhat working but then realized the connman README suggests enabling some WPA supplicant compiler options. After doing so I am now seeing problems when I attempt to power on WiFi. When I enable the power for the WiFi device it fails to create the interface within the supplicant. I think this then causes some problems in connman because the parts of the code have the interface marked as powered, yet if you attempt to scan it returns there is no power (error -ENOLINK or -67). So it seems some of the subsystems (Technology API) think the device is powered. Then lower level structures indicate it is off (driver->powered, in the scan routines).
My questions are: 1. Why will WiFi no longer power on/create the interface in the supplicant? What am I doing wrong? 2. Does this failure uncover some inconsistencies in tracking the power state in connman? More info: 1. My connman build is from commit: 3a92f7ef6945a8a24ebaf4bc191fdf51ea33d7b9<http://git.kernel.org/cgit/network/connman/connman.git/commit/?id=3a92f7ef6945a8a24ebaf4bc191fdf51ea33d7b9>(9/30/2013) 2. My HW is a Boundary Devices iMX nitrogen6x board with a TI-wl1271 WiFi chip. 3. I have verified WiFi does work on this HW using wpa_cli commands without the connman. 4. Previously worked inconsistently with 1.17 of the connman--with different unknown problems. So I thought I'd update connman to a more recent build. This also gave problems so I rebuilt wpa_supplicant with the new compiler options, and here I am. 5. My system does not have the nl80211 driver installed/built. It previously worked with wext support. 6. When I power on the WiFi device I do get the DBus signal indicating the "powered" property changed to true. 7. I start the connmand using: connmand -d -n -W wext & Any help would be MUCH appreciated.
