Nordic’s nRF52832 multiprotocol SoC combines a 64MHz, 32-bit Arm® Cortex® M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF protocol software) featuring -96-dB RX sensitivity, with 512kB Flash memory and 64kB RAM. The SoC is supplied with Nordic’s S132 SoftDevice, a Bluetooth 5-certifed RF software protocol stack for building advanced Bluetooth LE applications. The S132 SoftDevice features Central, Peripheral, Broadcaster and Observer Bluetooth LE roles, supports up to twenty connections, and enables concurrent role operation. Nordic’s software architecture ensures a clean separation between the RF protocol software and the Cleanbox application.
“We selected the Nordic nRF52832 SoC to provide the Bluetooth LE connectivity for the Cleanbox system due to its powerful integrated Arm M4F processor and Nordic’s S132 SoftDevice. The SoftDevice simplified our application code development and now allows us to perform secure over-the-air device firmware updates [OTA-DFUs] for Cleanbox system upgrades,” says David Georgeson, CTO at Cleanbox Technology.
“The excellent Nordic Software Development Kit and the strong support and quick response times of Nordic’s application engineers have also been very important.”
Short-range wireless connectivity is integral to these systems and both Bluetooth Low Energy and 2.4GHz proprietary offer compelling and complimentary use cases. The nRF52 Series multiprotocol SoCs can support both of these technologies simultaneously making them a very suitable family of devices for VR/AR applications.
