Phantom’s ELDA system uses two devices employing Nordic’s nRF52832 SoC for mesh networking between wall switch and LED drivers

Nordic Semiconductor today announces that Phantom, a Beijing, China-based electronic lighting component manufacturer, has selected Nordic’s nRF52832 Bluetooth® Low Energy (Bluetooth LE) System-on-Chip (SoC) to provide the wireless connectivity for its End-device level Distributed Automation (ELDA) system. In an ELDA system, end-devices such as wall switches and lights can communicate with each other directly through a Bluetooth mesh network, eliminating the need for complex and costly electrical wiring and meeting the requirements for smart lighting manufacturers and home automation companies.

The ELDA system consists of two integrated products: the NVCM3-BT control device for LED drivers (which regulate the power supply for the LED lighting); and the SNP12-BT battery-powered device that converts a conventional wall switch into a wireless product. Both the NVCM3-BT and SNP12-BT products employ the nRF52832 SoC. The Nordic technology enables Bluetooth LE wireless connectivity between the wall switch and each LED driver.

The installed wireless wall switch is installed in a home or office and the LED driver control device is installed into each light to form a Bluetooth mesh network, the user then flicks the switch to activate the light in the mesh network without recourse to a central hub. Mesh networking ensures that if any individual light is out of Bluetooth LE range of the switch, another light will automatically pass the message on.
Nordic has a great reputation for making wireless transceivers and we have been using previous generations of Nordic SoCs for a number of years
