Nordic’s nRF52832 SoC provides wireless connectivity for Control Bionics’ ‘NeuroNode’, enabling users suffering paralysis and loss of speech to control devices via electromyography

Nordic Semiconductor today announces that Control Bionics, a Milford (Cincinnati), Ohio-based developer of wearable electromyography (EMG) devices, has specified Nordic’s nRF52832 Bluetooth® Low Energy (Bluetooth LE) System-on-Chip (SoC) in its ‘NeuroNode’ device.

According to Control Bionics, the NeuroNode is the world’s first wearable EMG assistive technology device, giving those with amyotrophic lateral sclerosis (ALS)—also known as motor neurone disease (MND)—or any other condition causing paralysis and/or loss of speech the ability to communicate with family, friends, caregivers, and clinicians.

In operation, a small, non-invasive, medical-grade wireless sensor is placed on the skin over the muscle chosen to be the ‘switch’. When the user attempts to move that muscle, the NeuroNode interprets the signals sent from the brain to the muscle—even if there is no visible muscle movement—and uses those EMG signals to control the user’s paired computer, tablet, or smartphone.

Supported by the Nordic SoC, the NeuroNode system essentially functions as a wireless keyboard by connecting via the Bluetooth LE link to the user’s compatible device equipped with iOS/OSx, Android, or Windows. The NeuroNode works with most popular assistive scanning software such as Apple Switch Control and Google Switch Access.

By using the NeuroNode users with a disability are able to send and receive emails and text messages, play games, access social media, watch and download online entertainment, use environmental control systems, and operate external devices.

The NeuroNode uses a rechargeable LIR2032 battery, which has the same footprint as the common CR2023 battery but enables a substantially higher discharge current. The device is five times smaller than the NeuroSwitch (Control Bionics’ legacy EMG assistive communications device) and cuts power consumption by approximately 75 percent, thanks in part to the ultra low power characteristics of the nRF52832 SoC, which has 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.

Control Bionics has also developed an iOS companion app, the ‘NeuroNode Controller’, which allows the user and clinician to customize the NeuroNode to match the user’s abilities. The customized parameters are then saved to the NeuroNode for use with other platforms making it suitable for connection to a host of other devices via Bluetooth LE.

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-dBm 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.

“The availability of Nordic’s SoftDevice for Bluetooth radio management, along with the bootloader, meant we could concentrate on developing our application,” says James Schorey, Chief Technology Officer at Control Bionics.

“Our peers had said positive things about the support offered by Nordic, and that support has turned out to be superb. For example, when we were ready to apply for our FCC certification and we needed software to turn the NeuroNode into a generic 2.4GHz radio for the testing laboratory, Nordic provided a ready-made solution with online support that allowed us to take the radio test software and easily adapt it to our product.”

The sensor employs Bluetooth mesh software which enables users to instantly and simultaneously control up to hundreds of Bluetooth mesh-equipped lights from smartphones or tablets.

Once installed, the luminaires just need to be connected to mains power and can then be provisioned (“commissioned”), configured, and controlled directly from a mobile device using either smart-light maker Silvair’s iOS ‘Platform’ or Nordic’s iOS and Android ‘nRF Mesh’ intuitive apps. The nRF Mesh app, for example, enables a range of management features for use in Bluetooth mesh networks, allowing simple provision and configuration of Bluetooth mesh networks and devices. Either app allows the user to create lighting zones, enable and disable sensors, pair with switches, as well as set desired lighting levels.

Bluetooth mesh allows devices within a Bluetooth LE network to communicate directly with companion devices without recourse to a central hub device. Such a system extends communication range, flexibility, and reliability. Key applications for Bluetooth mesh include professional lighting installations, back-ends for managed beacons, and industrial monitoring.

Nordic’s nRF52832 SoC is a powerful multiprotocol SoC ideally suited for Bluetooth LE and 2.4GHz ultra low-power wireless applications. The nRF52832 combines an 64MHz, 32-bit Arm® Cortex™ M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF software) featuring -96dBm RX sensitivity, with 512kB Flash memory and 64kB RAM. The SoC’s powerful processor and generous memory can support the sensor’s complex mesh software, while the radio’s sensitivity ensures good range.

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.

“We selected Nordic’s nRF52832 SoC because of the capabilities of the Arm processor and the large memory capacity,” says Takeshi Sato, General Manager of IoT Business Promotion Department, Murata. “The availability of technical information from Nordic is also impressive.”

Nordic’s nRF52832 multiprotocol SoC supports Cardiosport’s ‘TP5 Heart Rate Monitor’, enabling transmission of medical-grade heart rate and heart-beat interval data to sports/healthcare apps and devices

Nordic Semiconductor today announces that Cardiosport, a Hampshire, U.K.-based OEM in the sports/healthcare industry, employs Nordic’s nRF52832 Bluetooth® Low Energy (Bluetooth LE) and ANT™ multiprotocol System-on-Chip (SoC) in its ‘TP5 Heart Rate Monitor’ (HRM).

TP5 is an advanced, customizable heart rate monitor platform designed to be modified, updated, and rebranded for fitness tracking and other applications/wearables in collaboration with a third-party OEM. The device features heart rate and movement sensors, along with a 3-axis accelerometer that can be programmed for running speed, pace, and cadence device profiles, as well as advanced running metrics like ground contact time, left/right leg balance and upper body position.

The integration of the Nordic SoC, which features a 2.4GHz multiprotocol radio supporting Bluetooth 5, ANT+, and proprietary 2.4GHz RF protocol software, allows the Cardiosport platform to transmit data via Bluetooth LE wireless connectivity to fitness apps hosted on Bluetooth 4.0 (and later) iOS and Android smartphones and tablets. The platform can simultaneously transmit data to ANT+ enabled devices such as smartwatches, bike computers, and fitness equipment.

The TP5 HRM uses a CR2032 coin cell battery to provide what Cardiosport describes as “industry-leading” battery life of 900+ hours, thanks in part to the ultra low power characteristics of the Nordic SoC. The nRF52832 has 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. Cardiosport also claims TP5 is one of the smallest and lightest HRMs on the market, with dimensions of 63 by 34 by 8.8mm and a weight of only 12g.

TP5 features a proprietary CBA9™ ECG ASIC chip for gathering extremely accurate heart rate data and r-r intervals (the time intervals between heart beats), thereby identifying individual heart beats during intense exercise, as well as meeting the requirements of medical ECG recorders.

The Cardiosport platform provides raw accelerometer data so developers are able to design apps around TP5’s functionality. For example, one Cardiosport customer uses the 3-axis accelerometer synched with the r-r intervals to monitor cardiovascular efficiency when the end user is running. Another customer integrates TP5 in clothing, through soft fabric ECG electrodes rather than a chest strap, to detect heart rate and r-r intervals in relation to the stillness and composure of the end user during yoga movements.

Programmable LED lights can be synched to the user’s heartbeat to change colour with HR zone, and display battery level and accelerometer movements. The LEDs offer up to nine different color configurations, while the functions can be changed for different TP5-based wearables via over-the-air device firmware updates (OTA-DFU).

Nordic’s nRF52832 multiprotocol SoC combines a 64MHz, 32-bit Arm® Cortex® M4F processor with the 2.4GHz multiprotocol radio featuring -96dB RX sensitivity, and generous 512kB Flash memory and 64kB RAM supporting complex applications and OTA-DFUs for Cardiosport customers.

The SoC is supplied with the S332 SoftDevice, a combination Bluetooth 5-certifed/ANT RF software protocol stack for building advanced Bluetooth LE and ANT applications. The S332 SoftDevice supports Central, Peripheral, Broadcaster and Observer Bluetooth LE roles, supports up to twenty connections, and enables concurrent role operation.

“We believe it is essential for heart rate monitor devices to incorporate support for Bluetooth LE, ANT+ and proprietary 2.4GHz protocols, which is one of the main reasons we selected the Nordic SoC,” says James MacGregor, Marketing and Business Development Manager at Cardiosport.

“Power consumption was also a very important factor when considering our choice of chip. The nRF52832 allows the TP5 Heart Rate Monitor to match the power consumption and battery life of Cardiosport’s previous TP3 Heart Rate Monitor, even though we have added LED lights, accelerometer/internal memory, and the ability to concurrently support Bluetooth LE & ANT+.

“Nordic’s nRF52 Series SoCs come with a lot of useful technical information, and the application engineers are always quick to respond to any queries,” adds MacGregor.

The gateway can control up to 16 devices simultaneously, thanks to the nRF52832 SoC’s ability to support multiple concurrent connections. The company has also developed a proprietary solution enabling the gateway to control up to 50 sensors. In this instance, the gateway receives status broadcasts from surrounding sensors and controls them individually as required. The broadcasts are fully encrypted to ensure security and privacy.

If the user is away from home, the gateway allows the user to remotely monitor and control the sensors from the ‘∑CASA (Sigma CASA) – SmartHome’ iOS or Android app on their mobile device via the ∑CASA Cloud Server. From the app the user can also schedule on/off times for peripheral sensors, group control multiple sensors, share devices amongst users, as well as create event triggers between multiple sensors. For example, if the ∑Door sensor is activated when someone opens the front door, the user can specify that event to trigger their ∑Lights to turn on, and their ∑Plug to activate an electric heater or fan.

Nordic’s nRF52832 mid-range SoC and nRF52810 entry-level SoC are powerful multiprotocol SoCs ideally suited for Bluetooth LE and 2.4GHz ultra low-power wireless applications, combining a 64MHz, 32-bit Arm® Cortex™ M4F processor (or M4 microprocessor in the nRF52810) with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT™, and proprietary 2.4GHz RF software). The nRF52832 SoC provides 512kB Flash memory and 64kB RAM, while the nRF52810 SoC offers 196kB Flash memory and 24kB RAM.

The nRF52832 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. The nRF52810 SoC is supplied with the latest version of Nordic’s S112 SoftDevice, a Bluetooth 5-compliant RF protocol software ‘stack’ offering 2Mbps raw data rate and concurrent Peripheral and Broadcaster Bluetooth LE roles.

According to Dexatek Technology, the nRF52832 SoC provided the processing power, memory capacity, and radio sensitivity required for its gateway. The company said battery life for the individual sensors was an important factor in the selection of the nRF52810, allowing for 6 months battery life between replacement under normal use.

“The nRF52840 is a cutting-edge platform with outstanding performance. It provides a lot of freedom in design and functionality of our thermostat, while simultaneously keeping costs down,” says Axel Jacobsen, CEO of Sikom.

“The most important features for us are the microprocessor capability and memory capacity, which enable swift development of complex applications running on a single core, without ‘hitting walls’ and wasting time on fine-tuning the performance or sacrificing functionality. The Nordic SoC’s radio sensitivity and support for Bluetooth 5 technology’s long-range feature also provides superior connection stability in difficult environments, significantly boosting range.

“The SoftDevice stability, Bluetooth 5, RTOS and multiprotocol support, and Software Development Kits (SDK) with drivers and example applications are all important features of the Nordic SoC,” adds Jacobsen.

“Nordic also offers an excellent support team with fast response and easy-to-use technical documentation, reference designs and tools, and hardware samples as required.”

Nordic Semiconductor today announces that Shenzhen DO Intelligent Technology (DO), a Shenzhen, China-based smart wearables company, has selected Nordic’s nRF52832 Bluetooth® Low Energy (Bluetooth LE) System-on-Chip (SoC) to provide the wireless connectivity and meet the processing demands of its ‘ID115plus Color HR’ wristband.

The wristband integrates a Nordic SoC-supervised accelerometer and heart rate sensor to track and record the user’s health and exercise data. It functions as a 24-hour dynamic heart rate monitor, sleep monitor, and activity tracker for steps taken, distance covered, calories burned, and activity duration. In addition, the wearable can provide weather forecasts, sedentary alerts, a smart alarm, and message notifications for up to 16 applications including calendar, email, SMS, Facebook, WhatsApp, WeChat, and Skype.

Using the Bluetooth LE wireless connectivity provided by the Nordic SoC, exercise data is synced to the user’s Bluetooth 4.0 (and later) smartphone or tablet, where the information can be reviewed via DO’s iOS- and Android-compatible app, Veryfit Pro. From the app, users can also configure the wristband’s various settings and functions.

Weighing a lightweight 24.8g, the wristband comes in a 240 by 19.2 by 12mm form factor and features a TFT LCD color display and IP68 water resistance. Supported by the ultra low power consumption of the Nordic SoC, the device’s Li-ion battery provides between seven and ten days of continuous operation.

Nordic’s nRF52832 SoC is a powerful multiprotocol SoC ideally suited for Bluetooth LE and 2.4GHz ultra low-power wireless applications. The nRF52832 combines an 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.

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.
