Abstract

A lighting system includes lighting devices and a controller. An Over-The-Air (OTA) update of lighting device programming is delivered via point-to-point connections between the controller and some number of lighting devices and/or between the lighting devices. Delivery of the OTA update from one lighting device to another lighting device is triggered based on an update command sent via a wireless mesh network of the lighting system.
