Technical Description

The BubblyNet GPS based TimeKeeper is the ideal solution to keep time synchronized across the Bluetooth® Mesh network correcting time drift caused by environmental changes such as temperature and humidity. With the BubblyNet GPS based TimeKeeper the scheduled events on the Bluetooth® Mesh network will stay synchronized with an accuracy of less than one second. The BubblyNet GPS based TimeKeeper will publish a time update message several times per day to keep all the devices synchronized.

The BubblyNet GPS based TimeKeeper is required for Bluetooth® Mesh installations that uses Scheduled Events that specify high accuracy (less than 10 seconds.) The Bubblynet GPS based TimeKeeper features a 9’10” (3M) cable attached to the external antenna for easy installation. Position the antenna in a window where it has direct line of sight to the sky to receive the GPS signals. The best reception is achieved when the GPS antenna has ample open space surrounding it.

For best results, drivers need to be installed within 30 feet of the closest device within the Bluetooth® Mesh network. Signal strength significantly decreases in presence of metal barriers such as when devices are enclosed in metal boxes. The Antenna must be least 20mm from any metal, concrete, or brick, and the antenna cable must be straight, and neither coiled nor looped.
