TCI Telecomunicazioni Italia’s ‘BlueLightLink’ employs Nordic’s nRF52832 Bluetooth Low Energy SoCs allowing wireless remote control of potentially up to 32,000 lighting devices simultaneously
The company is also set to release its ‘BLL PLUS’ iOS app, which will allow the user to control multicolor TCI LED drivers and ‘tune’ the color and temperature of the LEDs. From both apps, the user can easily configure and control groups of lights, as well as set-up multiple light ‘scenarios’.
Nordic’s nRF52832 Bluetooth LE SoC, a member of Nordic’s sixth generation of ultra low power (ULP) wireless connectivity solutions, combines a 64MHz, 32-bit ARM® Cortex® M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™ and proprietary 2.4GHz RF software) featuring -96dB RX sensitivity, with 512kB Flash memory and 64kB RAM. When launched, the SoC was the world’s highest performance single-chip Bluetooth LE solution, delivering up to 60 percent more generic processing power, offering 10 times the Floating Point performance and twice the DSP performance compared to competing solutions.
The nRF52832 SoC has also been engineered to minimize power consumption with features such as the 2.4GHz radio’s 5.5mA peak RX/TX currents and a fully-automatic power management system that reduces power consumption by up to 80 percent compared with Nordic’s nRF51 Series SoCs. The result is a Bluetooth LE solution which offers 58 CoreMark/mA, up to twice as power efficient as competing devices.
“We selected the nRF52832 SoC for its low power consumption, ample Flash and RAM memory, and good RF performance,” says Moreni. “The nRF52832 SoC was the first chip that met the high performance requirements of the BlueLightLink application, and that featured a ready-working SoftDevice [RF protocol stack] enabling Over-The-Air Device Firmware Upgrades [OTA-DFU].”
