Blueforce Tactical is extensible through the construction and provisioning of "plugins". These plugins are made available to BTAC users via the equivalent of a "Plugin Store".
BTAC settings uses the SOFTWARE UPDATE URL value to define where BTAC will look for plugins. If this value is incorrect or unreachable, the user will see a quick flash when he/she goes to look for available plugins by tapping the ALL tab in the Sensors area of BTAC.
BTAC uses port 80/HTTP to query and communication with the "plugin store"..
