The nLight Handheld Programmer uses a Bluetooth Low Energy BLE Radio Module to allow wireless communication between the local nLight zone and iOS/Android smart phone application, nConfig. This device offers two RJ-45 ports to be placed in any location on a local nLight zone, and the unit powers up directly off of the nLight bus. The smart phone application offers secure pairing with the BLE device when within range, and once connected can be used for identifying and configuring devices within that zone.
