App Description
Quickly configure Gefran devices via NFC
The Gefran NFC application allows you to configure solid state relays and power controllers enabled for NFC technology (GRP series). This technology allows the exchange of data between smartphone and device. Data exchange can be used to read or write configuration recipes, model information, and diagnostic data. The application allows you to open recipes from the smartphone memory, read them from the device and retransmit them to it or similar devices.
All the reading and writing operations can be performed with the device powered or NOT powered.
The data exchange takes place by bringing the Gefran NFC Dongle, an accessory that can be ordered separately or together with the device, to the NFC antennas of the smartphone. The NFC Dongle is not the memory of the device, but just an antenna, which allows communication at close range.
It is also possible to save and forward recipes in .gfe format (Gefran format common to GF_eXpress recipe files).
