Actually, there are just 3 examples now.

Yes, this is correct.

This is, however, not the path of your connection, but path of the AP you want 
to connect to. This path should be the last parameter (specific_object) of 
ActivateConnection - instead of "/"; see ActivateConnection description.

As I've written, connections are configured set of settings and you can see 
them in nm-connection-editor (right click on nm-applet and choose "Edit 
connections"). They are provided by so called setting services, which of them 
are two: user and system service.
That's why SERVICE variable should be
SERVICE = "org.freedesktop.NetworkManagerSystemSettings"
or
SERVICE = "org.freedesktop.NetworkManagerUserSettings"
And the CONNECTION will look like this:
CONNECTION="/org/freedesktop/NetworkManagerSettings/1"

Use:
SERVICE="org.freedesktop.NetworkManagerUserSettings"
CONNECTION="/org/freedesktop/NetworkManagerSettings/1"
DEVICE="/org/freedesktop/NetworkManager/Devices/0"
AP="/org/freedesktop/NetworkManager/AccessPoint/15" 

dbus-send --system --print-reply --type=method_call --
dest='org.freedesktop.NetworkManager' \
'/org/freedesktop/NetworkManager'
org.freedesktop.NetworkManager.ActivateConnection \
string:"$SERVICE" objpath:"$CONNECTION" objpath:"$DEVICE" objpath:"$AP"

The number in CONNECTION may be different, according to your configured 
connections.

For list of D-Bus connection paths you can use,
for user connections:
dbus-send --system --print-reply  --type=method_call \
--dest='org.freedesktop.NetworkManagerUserSettings' \
'/org/freedesktop/NetworkManagerSettings' \ 
org.freedesktop.NetworkManagerSettings.ListConnections

for system connections:
dbus-send --system --print-reply  --type=method_call \
--dest='org.freedesktop.NetworkManagerSystemSettings' \
'/org/freedesktop/NetworkManagerSettings' \ 
org.freedesktop.NetworkManagerSettings.ListConnections

If you didn't create a connection via nm-connection-editor, you can just left-
click nm-applet and you can see available APs. When you click an AP, a new 
connection is created (named "Auto your_AP_SSID").

A nice python script is also here:
