Hi,
I'm in the process of developing a Yocto-based embedded solution (Wi-Fi only, similar
to Raspberry Pi Zero W) with connman as the network manager. This solution needs to pass
Apple's Bonjour Conformance Tests, and I've been having some difficulties getting
the current version (1.38) of connman to pass.
I've set the AddressConflictDetection option to true in connman's main.conf which
helps me get through most of the IPv4LL tests, but the hot-plug tests (where you have to
force the Wi-Fi interface to disassociate from the AP) are failing.
Thoughts?

I find a similar thing. If I reboot my router, connman never rejoins the
wifi SSID. I have to reboot or restart connman to get it to reconnect. I
thought that my php scripts may be interfering with it, but have noted this
behavior. I have not taken enough time to diagnose it, yet.

I have also seen the problem of WiFi not reconnecting until ConnMan is
restarted. For me, it happens after re-association to the same SSID
(performed automatically). After this happens, if the WiFi connection is
lost (AP is cycled), ConnMan does not detect any changes to the connected
service and continues to show that it is "Online", even when it isn't.
ConnMan never re-associates to the AP and can only be recovered by
restarting ConnMan.
I'm not sure if it is related, but I am running ConnMan with
SingleConnectedTechnology=true.
I also have been unable to figure out the root cause of the issue.

I am using iwd to manage the wireless side. Maybe that is it? I have not
tried with wpa_supplicant to see if it follows or not.

It might be that the auto connect algorithm doesn't decide to reconnect

Hi Daniel,
Here is a log file capture of when it does not reconnect automatically. I
have added a row of *'s to mark the location, but I've included the whole
log for completeness. Also, I've copied the contents of the main.conf file.
------------------------
$ cat /etc/connman/main.conf
[General]
FallbackTimeservers = 0.pool.ntp.org, 1.pool.ntp.org, 2.pool.ntp.org,
3.pool.ntp.org
FallbackNameservers = 8.8.8.8, 8.8.4.4
AllowHostnameUpdates = true
PreferredTechnologies = wifi,ethernet
SingleConnectedTechnology = true
BackgroundScanning = true

Just ran into this again, today when my son rebooted the router, all WiFi
Pis lost their connection and did not reconnect. Anything we can do to
help diagnose this?
Does the setting 'background scanning' do anything if you are using iwd?
Could that be why it doesn't reconnect?
'connmanctl scan' does not work with iwd...

No, it should not. As long ConnMan lists gets of station, there nothing
we need to tweak on wpa_supplicant or iwd. So if 'connmanctl services'
lists the service, all should be okay.

I think it's missing the autoconnect flag.
'connmanctl scan' does not work with iwd...
Hmm, which version of iwd and ConnMan are you using. Versions before
ConnMan 1.38 do not work with recent iwd versions.
Thanks,
Daniel

connmanctl config <service> --autoconnect yes
it appears so:
~# connmanctl services wifi_b827eb52ccd0_73706733_managed_psk
/net/connman/service/wifi_b827eb52ccd0_73706733_managed_psk

IPv4.Configuration = [ Method=dhcp ]
IPv6 = [ Method=auto, Address=2601:241:4200:28d:ba27:ebff:fe52:ccd0,

Proxy.Configuration = [ ]
mDNS = False

When querying it via iwctl, though it shows that it is not set:
# iwctl known-networks spg3 show
Known Network: spg3
--------------------------------------------------------------------------------
Settable Property Value
--------------------------------------------------------------------------------
Name spg3

* AutoConnect no
and I cannot seem to be able to set it

~# iwctl known-networks spg3 show
Known Network: spg3
--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
Name spg3
Hidden
* AutoConnect no
If I edit the /var/lib/iwd/spg3.psk file to change the AutoConnect value
from 'false' to 'true', it immediately changes back.
Is connman controlling this?
?

Hmm, which version of iwd and ConnMan are you using. Versions before
ConnMan 1.38 do not work with recent iwd versions.
I built the latest connman from git (just in case?) and iwd is the 'latest'
from Arch.
connman-git 1.38.r11.g82699007-1
iwd 1.8-1
Oh, scanning does work now with iwd from connman! Sorry for mentioning it.
I guess that 'feature' came with an upgrade to iwd from 1.7 to 1.8.
Woo Hoo and thanks! This simplifies our PHP scripts.
This behavior of not reconnecting when the router is rebooted is noted on
an RPiB3+ running aarch64, an armv6 install on the RPi_Zero and on an armv7
install on a RPiB3.
All have Autoconnect=true
Thanks,
Daniel
3:45 p.m.
~# connmanctl services wifi_b827eb52ccd0_73706733_managed_psk

Okay. So in the case it does not reconnect, does ConnMan list the WiFi
services at all? I try to reproduce this evening.
If I edit the /var/lib/iwd/spg3.psk file to change the AutoConnect
value
from 'false' to 'true', it immediately changes back.
Is connman controlling this?
Yes, if you use iwd with ConnMan together, the auto connection of iwd
will be disabled by ConnMan.

Could it be, that ConnMan just not getting notified that the link went
down? Could you monitor what iwd sends via D-Bus to ConnMan
(monitor-iwd)?
