How to persist connmanctl settings

I’m having a lot of trouble with connmanctl on my beaglebone black rev C. Most of the time it won’t connect to my router, and when it does the settings don’t persist after a reboot.

Here are some details:

bbb4g# uname -a
Linux bbb4g 4.4.30-ti-r64 #1 SMP Fri Nov 4 21:23:33 UTC 2016 armv7l GNU/Linux

(I had previously connected, which is why - I assume - it doesn’t ask me for a password this time)

bbb4g# connmanctl

After rebooting, my wifi adapter doesn’t power up. dmesg says “[ 32.629972] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready”. systemctl status shows

bbb4g$ systemctl status connman
● connman.service - Connection service

Can anyone here point me in the right direction?

Thanks
