Hi Giacinto, I tried to run openwrt on my embedded system, it got netifd daemon to manage the LTE modem, and started udhcpc -p /var/run/udhcpc-wwan0.pid -s /lib/netifd, that problem has gone away.
Now I am really worried, if the problem of lost LTE network IP address only happened in connman not in openwrt, it will unlikely be the carry network and modem issues, could it be because that openwrt used udhcpc to refresh the IP address? How does the connman manage the dhcp for LTE IP address? Thank you.
