The Luke Roberts Smart Lamp integrates Nordic’s nRF52832 SoC allowing iOS or Android smartphone or tablet users to direct light to any part of the room, change lamp color, and set room ambience
Nordic’s nRF52832 Bluetooth LE SoC, a member of Nordic’s sixth generation of ultra low power (ULP) wireless connectivity solutions, combines the ARM 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.
The SoC is supplied with Nordic’s S132 SoftDevice, a Bluetooth 4.2 qualified RF software protocol stack for building advanced Bluetooth LE applications. The S132 SoftDevice supports Central, Peripheral, Broadcaster, and Observer Bluetooth LE roles, supports up to twenty connections, and enables concurrent role operation.
“We initially chose the Nordic nRF52 Series SoC for its enhanced RF capabilities―including Bluetooth 5 support, good link budget, and on-chip Balun―and processing power. These attributes enabled us to implement all the features we envisioned without compromise due to technical constraints,” says Lukas Pilat, Co-founder of Luke Roberts. “Moreover, Nordic’s Software Development Kit [SDK] and the clean separation of Bluetooth stack software [SoftDevice] from our application code simplified the design process.
“As a start-up, the choice of design partner and chip is a tough one, as a wrong decision might be fatal for the entire company. Nordic’s proven technology and start-up friendly approach gave us confidence in our choice,” explains Pilat. “For example, Nordic’s reference designs simplified hardware design and on the software side, the open-source friendliness of Nordic also proved an advantage. We also realized we could rely heavily on Nordic’s firmware and application code examples without needing to ‘reinvent the wheel’ each time.”
The Luke Roberts Smart Lamp will be commercially available by the end of 2017 for both consumers and larger commercial lighting installations such as offices, bars, or restaurants across Europe and North America.
