* o (originator interval in ms) - a node transmits broadcast messages (we call them [http://www.open-mesh.org/projects/batman-adv/wiki/OGM originator message or OGM], [http://www.open-mesh.org/projects/batman-adv/wiki/Ogm-v2 version 2]) to inform the neighboring does about it's existence. Originator interval is the time to wait after sending one message and before sending the next message. The default value is 1000 ms (1 second). In a mobile network, you may want to detect network changes very quickly, so you need to send message very often, for example, use a value of 500 ms. In a static network, you can save bandwidth by using a higher value. | * o (originator interval in ms) - a node transmits broadcast messages (we call them [http://www.open-mesh.org/projects/batman-adv/wiki/OGM originator message or OGM], [http://www.open-mesh.org/projects/batman-adv/wiki/Ogm-v2 version 2]) to inform the neighboring does about it's existence.

This configuration is valid for [http://wiki.openwrt.org/about/history OpenWRT 12.09] (Attitude Adjustment), which uses BATMAN 2012.4.0. In newer versions, the version of BATMAN used is 2013.0.0 and the configuration of BATMAN slightly differs. | This configuration is valid for [http://wiki.openwrt.org/about/history OpenWRT 12.09] (Attitude Adjustment), which uses BATMAN 2012.4.0.

In /etc/config/system you can set hostname and timezone. This is not strictly necessary for BATMAN to work, but it should be set correctly. The below timezone is correct for the pacific U.S. timezone. The naming convention for hostnames is: <router-model-name>-<some-unique-name-you-choose> | In /etc/config/system you can set hostname and timezone.
