Geocached Zone

Has anyone implemented a solution triggering an event with a zone? I am looking to develop a solution that tracks when a tag passes through a line on the floor. Think of it like a football field and I want to track when a tag passes each yard marker and call a function to do something. Would this be best done using the C API and managing on the hardware or done on a local application level? My long term thought would be to handle this at the Gateway level when that becomes available, hopefully soon…

Any design thoughts or examples here?



Hi Jim, if you set a listener and read the data using serial port (Lec, les) you could trigger an event if a tag is inside a polygon.
