Daniel,
I appreciate the work on this. Something is strange, though. I just built
connman to the HEAD which is "b0711230"
I just tried a router reboot and nothing reconnects, now. I was able to see
it try then fail.
If I restart connman. no reconnect
If I restart iwd then connman no reconnect.
I used to be able to make it reconnect if I took the network down than back
up (ifconfig wlan0 down; ifconfig wlan0 up), but that also does not work
from this state.
If I try to reconnect via connmanctl, it says 'Not registered' though when
I ask for services, the SSID is listed with "*A" in front of it.
If I peruse the journal, it connects, adds all the addresses then
disconnects:

If I reboot, it connects with all the addresses and works fine. Is there a
line in the *.config that I need to have set so it reconnects properly?
Right now, I have a coinfig set up like this and it connects at boot:
[global]
Description=DHCP PSK Wi-Fi network configuration for network (SSID)
"mySSID", with SSID hex value "mySSID_HexValue"
[service_mySSID_HexValue]
Type=wifi
SSID=mySSID_HexValue
Security=psk
Passphrase=password
Hidden=false
Are there specific settings in /etc/connman/main.conf that I need to set?

The problem could be that the M and O flag are not set in the RA. As<br>
