I think you are trying to use ConnMan as a DHCP client to configure
the network interface of your device. This client is part of ConnMan,
and it needs to connect to some DHCP server to obtain an IP address (a
lease) and related configuration.
The DHCP server usually runs on some server or router. If no DHCP
server can be discovered on your network, then you'll get a link-local
address in block 169.254.0.0/16, which is probably useless for you.
According to your log, a DHCP client request was started at 00:00:08,
and it timed out 30 seconds later at 00:00:38. Ten seconds later, you
got address 169.254.47.3 as a fallback.
So there seems to be no DHCP server on your network. In this case you
need to enable the DHCP server on some device on your network, or use
manual IP configuration without DHCP. If you know there is a DHCP
server, then you should read its log to find out if perhaps your DHCP
client request got filtered out.
(As I just found out, there is also a DHCP server inside ConnMan, but
it seems not to be useful for this use case.)
