connman: wifi configuration

Sergey has detailed directions at the bottom of this page for connmanctl here so, no need to rewrite that.

I also found a tutorial on the Intel Developer Zone here that discusses how to use connman.

I used this guide to configure to my home wifi. Either follow his instructions or just refer to my printout below for an example of a successful attempt.

root@quark0171ae:~# connmanctl
connmanctl> enable wifi
Enabled wifi

It will print:

connmanctl> [  138.361118] iwlwifi 0000:01:00.0: L1 Disabled; Enabling L0S
[  138.377075] iwlwifi 0000:01:00.0: Radio type=0x2-0x1-0x0
[  138.800255] iwlwifi 0000:01:00.0: L1 Disabled; Enabling L0S
[  138.815868] iwlwifi 0000:01:00.0: Radio type=0x2-0x1-0x0
[  139.072513] IPv6: ADDRCONF(NETDEV_UP): wlp1s0: link is not ready

Then scan for services and list them:

connmanctl> scan wifi
Scan completed for wifi
connmanctl> services

Here are the services at my house for example:

    rip and run guest network wifi_c8f733840a94_72697020616e642072756e206775657374206e6574776f726b_managed_psk

Exit connmanctrl now that you know the networks and build a wifi config file to save your settings. This file is located in a folder /var/lib/connman where you can save multiple configurations. The default is wifi.config so I usually make copies of other configurations and swap them out. But I think this service will scan through them if you enable autoconnect inside the interactive version of connmanctrl.

Here is how you make that file:

root@quark0171ae:~# cat << EOF > /var/lib/connman/wifi.config
> [service_wifi_c8f733840a94_726970616e6472756e62616279_managed_psk]
> Type = wifi
> Security = wpa2
> Name = ripandrunbaby
> Passphrase = yourpass
> EOF

My connman connnected at this point automagically:

root@quark0171ae:~# /et[  301.244385] wlp1s0: authenticate with 60:33:4b:e4:4b:9b
[  301.269889] wlp1s0: send auth to 60:33:4b:e4:4b:9b (try 1/3)

[  301.348997] wlp1s0: associated
[  301.352244] IPv6: ADDRCONF(NETDEV_CHANGE): wlp1s0: link becomes ready

If you don't see this if you have a connection:

-sh: /et: No such file or directory
root@quark0171ae:~# ping google.com
PING google.com (74.125.239.39): 56 data bytes
64 bytes from 74.125.239.39: seq=0 ttl=55 time=15.315 ms

And try restarting the service:

root@clanton:# systemctl stop connman
root@clanton:# systemctl start connman
