If you run ifconfig -a does your WiFi interface show up? If not there is anNot that bad, the WiFi interfaces was fine, but it could not get dhcp

This would typically mean that you are actually connected to a wifi network but the interface did not receive a DHCP lease for the IP address. the 169.254. is local IPv4 IP address which the interface would typically get if the DHCP client times out.
I could see WiFi information well, it is not a major problem, but the
subtle issues are connman and wpa_supplicant did not set up the WiFi

I don't think that this is a wpa_supplicant issue. However, you can use connmanctl to manually connect to a wifi network:
connmanctl> enable wifi
connmanctl> scan wifi
San completed for wifi
[service list follows]
connmanctl> agent on
connmanctl> connect wifi_xxxxxx
Agent RequestInput wifi_xxxxx
Passphrase = [ Type=psk, Requirement=mandatory ]
If that works the wifi authentication is OK.
Did you install the regulatory database?Did you mean to enable CONFIG_CFG80211_INTERNAL_REGDB? No, I did not
install it in the Zeus version either so I don't see that could be an
Only a wag on my side. Should be ok since the wifi driver is working.
What error messages are you seeing when attempting to connect to a WiFiNo error in connman, I don't think it is connman or wpa_supplicant
network? Did you look at the connman logs?
issue, my suspicion is something missing in Honister built image to
prevent connman and wpa_supplicant to set up the WiFi driver
It is not the first time I have the WiFi setup trouble to get WiFi
169.254 address, when I upgraded from Thud to Zeus, I got the exactly
the same problem that WiFi was assigned by a 169.254 address, no dhcp
response, at time, I was totally convinced it was connman issue, I
spend several months to debug connman and wpa_supplicant without any
results, then after waiting several months to pull updated Zeus again,
that problem was disappeared miraculous, that is why I suspect the
same problem in oe-core and bitbake in Honister as well.
Well, ok then it looks like a dhcp issue. Did you attempt to set a static IP to test connectivity?
Eventually it could be a router issue. Maybe the router blocks unknown devices?
Are there anyone in oe-core and bitbake tested connman, wpa_supplicant
for the current Honister branch? I can help to test and to debug it if
more advanced people in oe-core, bitbake, kernel, WiFi driver mwifiex
can provide me more information.
Honestly, I don't think the issue is related to connman or wpa_supplicant at all but on the dhcp level.
