Book 25:
NFC Readers with Bluetooth interface for in-field programming


An increasing number of lighting applications requires reading out parameters and changing of settings of LED drivers in the field.
Manufacturers of LED luminaires currently use a variety of methods for in field programming. Zhaga aims to give installers, system integrators and utility companies the option to select only one programming tool which works with all field-maintenance applications from all vendors implementing Book 25.
Zhaga Book 25 builds on Book 24, Programming of luminaire components using NFC, but now includes mobile NFC Readers with a Bluetooth interface. It enables maintenance and replaceability with a cross vendor harmonized method of NFC programming for in-field use.
The specification defines a Bluetooth communication protocol (GATT-Service) which NFC Reader manufacturers can implement for the communication between the field-maintenance application on a smart device (cell phone, tablet, etc.) and the NFC reader. This allows the field-maintenance app to read and write parameters on NFC enabled LED drivers without the need for a cable-based connection. Field maintenance with Book 25 may also be used for other components requiring programming, such as sensors or connectivity nodes.
