‘SPO2 Wristband Solution’ from Veepoo employs Nordic’s nRF52832 SoC to wirelessly monitor users’ blood oxygen saturation values and linked sleep apnea syndrome

Nordic Semiconductor today announces that China-based, Veepoo, integrates Nordic’s award-winning Bluetooth® Low Energy (Bluetooth LE) nRF52832 System-on-Chip (SoC) in its ‘SPO2 Wristband Solution’. The product enables OEMs without RF design expertise to rapidly develop health-based wearable solutions for the middle-aged to elderly, smokers, and other people with suboptimal health, particularly those with interstitial breathing, heart disease, or sleep apnea syndrome.

SPO2 Wristband Solution allows OEM develpers to design products that monitor arterial oxygen saturation and in turn estimate the oxygenation capacity of the lung along with the blood’s hemoglobin carrying capacity. Nordic’s nRF52832 SoC provides Bluetooth LE wireless connectivity between the wristband and a Bluetooth 4.0 (and later) iOS or Android smartphone.

From the smartphone, users can access important health updates via Veepoo’s companion app. For example, the app allows users to monitor the change in blood oxygen during nocturnal sleep and therefore to test for abnormal metabolism, hemodynamic disorder, or sleep apnea syndrome. If blood oxygen saturation decreases to a hazadous level, the wearable device will automatically trigger an alarm to warn the user and/or caregiver of the danger.

The Nordic SoC’s 64MHz, 32-bit ARM® Cortex® M4F processor provides ample computing capacity to power Veepoo’s unique algorithm which enables the SPO2 Wristband Solution to accurately measure blood oxygen saturation values from weak arterial signals at the wrist in addition to the strong signals from the fingers. Standard medical devices are limited to finger measurements only.

The device’s algorithm capitalises on the fact arterial blood absorption of light varies with arterial pulsation. In addition, oxygenated and deoxygenated arterial blood hemoglobin have different light absorption rates at different wavelengths. A photosensitive element embedded in the hardware detects changes in arterial pulsation and light absorbtion due to varying oxygenation levels and the software eliminates the effects of non-blood tissue then calculates actual blood oxygen levels.

The low power consumption characteristics of the Nordic SoC help prolong the service life of SPO2 Wristband Solution’s portable lithium battery, meaning it can charge and discharge approximately 7000 times while supporting 15-plus days of standby time―an important consideration for a health-based wearable.Nordic’s nRF52832 Bluetooth LE SoC, a member of Nordic’s sixth generation of ultra low power (ULP) wireless connectivity solutions, combines the 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.

The SoC is supplied with Nordic’s S132 SoftDevice, a Bluetooth 5-certified RF software protocol stack for building advanced Bluetooth low energy applications. The S132 SoftDevice supports Central, Peripheral, Broadcaster, and Observer Bluetooth low energy roles, supports up to twenty connections, and enables concurrent role operation.

“We selected the nRF52832 SoC for its superior technical aspects,” says Jiuchao Li, CEO at Veepoo. “The powerful CPU computing capability meets our algorithm requirement and supports floating point operation, the RAM and Flash meet our specification requirements, and the low power characteristics ensure SPO2 Wristband Solution can be used for a longer period of time.

“Our SPO2 Wristband Solution benefits from the clean separation between Nordic’s SoftDevice and the application code, allowing our engineers to work directly on application software. The easy-to-use Software Development Kits [SDKs] also greatly reduce the development challenge,” says Jiuchao Li.

“Throughout the SPO2 project, Nordic application engineers have provided us with fast and helpful responses to our enquiries, which has contributed to a smooth R&D schedule.”

‘Nima’ employs Nordic Semiconductor’s Bluetooth Low Energy nRF51822 SoC to wirelessly sync test data to smartphones and tablets

Nordic Semiconductor today announces that San Francisco, CA-based Nima has released its ‘Nima’ gluten sensor, a Bluetooth® Low Energy wirelessly connected device that tests food for the presence of allergens in just a few minutes. Nima employs Nordic’s multiple award-winning nRF51822 System-on-Chip (SoC) to provide Bluetooth LE wireless connectivity between the device and Bluetooth 4.0 (and later) smartphones and tablets.

Nima uses antibody-based chemistry to test samples of food for the proteins found in wheat, barley, and rye that causes reactions for people with celiac disease, wheat allergies, or gluten sensitivities. In operation the user places a small sample of food into a disposable test capsule, inserts the capsule into the Nima device, and pushes a button to begin testing. After three minutes the device will notify the user if gluten has been detected in the test sample. The device was designed to detect gluten in food samples at 20 parts per million (ppm) or above with 99 percent accuracy. If it detects gluten at any level, even below 20 ppm, the result will read “Gluten Found”.

Using Bluetooth LE wireless connectivity provided by the nRF51822 SoC, captured data is synced to the accompanying Nima iOS and Android app, allowing users to save their test results and share them with the Nima community, rating food and restaurants based on how gluten-free friendly they are. In the absence of a smartphone, test results are stored locally on the Nima device until the next opportunity to download them.

Nima employs a 300mAh rechargeable Li-ion polymer battery that can achieve more than 30 tests between recharge—or six months in sleep mode—thanks in part to the ultra-low power consumption of the Nordic SoC.

Nordic’s nRF51822 is a powerful and flexible multiprotocol SoC ideally suited for Bluetooth LE and 2.4GHz ultra low-power wireless applications. The nRF51822 is built around a 32-bit ARM® Cortex™ M0 CPU, 2.4GHz multiprotocol radio, and 256kB/128kB Flash and 32kB/16kB RAM. The SoC is supplied with Nordic’s S130 SoftDevice, a Bluetooth 4.2 qualified concurrent multi-link protocol stack solution supporting simultaneous Central/Peripheral/Broadcaster/Observer role connections.

“When we looked at our wireless connectivity options we opted for Bluetooth LE because of the simplicity of the protocol, the low power consumption, and the compatibility with a wide range of devices and smartphones,” says Scott Sundvor, Nima Chief Product Officer and Co-founder. “Specifically we went with Nordic’s nRF51822 SoC because of the combination of the ARM Cortex M0 CPU with the 2.4GHz radio in one small package.

“On top of which the Nordic SoftDevice, reference designs, and nRF51 development kit helped reduce our time to market, and our development costs.”

Nordic’s nRF52840 multiprotocol SoC is now Thread certified and enables simultaneous Thread and Bluetooth 5 connectivity for the first time

Courtesy of Nordic Semiconductor

Nordic’s nRF52840 System-on-Chip (SoC) with ‘Dynamic Multiprotocol’ feature uniquely supports concurrent Thread and Bluetooth 5 wireless connectivity (eliminating the need to disconnect from one network before connecting with another). This capability also ensures any Thread product based on the Nordic nRF52840 SoC and Nordic nRF5 SDK for Thread is seamlessly interoperable with Bluetooth 5 devices

Nordic Semiconductor today announces that its latest multiprotocol SoC, the nRF52840, which supports both Bluetooth® 5 (Bluetooth low energy) and IEEE 802.15.4 (the foundation of the Thread networking standard together with the OpenThread stack) is now Thread 1.1 Certified. The nRF52840 SoC passed all Thread certification tests while supporting Bluetooth 5 connectivity to a central device. The tests demonstrated the nRF52840 SoC’s capability to support applications that concurrently use Thread and Bluetooth 5 wireless networks (eliminating the need to disconnect from one network before connecting with the other).

Nordic’s nRF52840 SoC is the only multiprotocol SoC on the market that offers this concurrent Thread and Bluetooth 5 support. The capability is enabled by the SoC’s Bluetooth low energy and Thread ‘Dynamic Multiprotocol’ feature (see below) which allows simultaneous support of Nordic’s S140 v5 SoftDevice (the Bluetooth low energy protocol stack for the nRF52840 SoC and part of Nordic’s nRF5 Software Development Kit (SDK) for Thread) and the OpenThread RF protocol stack. OpenThread is the first open-source Thread-certified implementation of the Thread networking protocol, released by Nest Labs, and to which Nordic Semiconductor actively contributes R&D expertise.

For developers, this means that any wireless sensor or product that employs a Nordic nRF52840 SoC can now not only quickly and easily gain Thread Certification, but also be interoperable with (and be commissioned, controlled, or managed by) a Bluetooth v4.0 (and later) wireless technology device, benefiting from both wireless technologies at the same time.

“In operation, the nRF52840 can effectively work as a bridge between Thread and Bluetooth 5 networks, and can communicate with, for example, both a smartphone over Bluetooth 5, and a Thread wireless sensor, enabling data to be exchanged between them without going via the Cloud,” says Pär Håkansson, a Product Marketing Manager at Nordic Semiconductor.

“What’s more, although this isn’t a truly simultaneous connection, Nordic’s R&D teams have engineered the process to be so quick and seamless that developers can consider it as practically simultaneous when designing their applications. Better yet, all the ‘heavy lifting’ to support this connectivity is hidden within the lower-level drivers of the Nordic S140 v5 SoftDevice eliminating the need for developers to have to worry about it.”

Thread was designed to create the best way to connect and control products where people live and work. The protocol includes robust security (smartphone-grade authentication and AES encryption), low power battery-friendly operation, reliability, scalability, and support for a developer-friendly IP-based (IPv6 with 6LoWPAN) mesh networking.

The non-profit Thread Group states that it is focused on making Thread the foundation for the IoT in the home and beyond by educating product developers, builders, and consumers on the unique features and benefits of Thread, while ensuring a positive experience through rigorous, meaningful product certification. Prime home IoT target applications for Thread include: home automation, appliances, access- and climate-control, safety, lighting, healthcare, and security systems.

“Nordic Semiconductor continues to be a valuable and committed contributor to OpenThread,” comments Jonathan Hui, Technical Lead and Original Architect of OpenThread at Nest. “And the expeditious path of nRF52840’s Thread certification is a testament to the benefits of OpenThread’s open-source approach, portability, and optimized footprint.”

“Nordic Semiconductor has been a long and active participant in the Thread Group and is making meaningful contributions towards helping Thread deliver on its potential,” adds Grant Erickson, President of the Thread Group. “We’re very pleased to see Nordic introduce their Thread-certified nRF52840 SoC to satisfy growing demand for low-power, IP-based mesh networks such as Thread, which seamlessly connect hundreds of devices to each other, to mobile devices, and directly to the cloud, without compromising battery life.”

“We see Thread as one of the leading wireless technologies currently emerging in the home IoT space,” comments Geir Langeland, Nordic Semiconductor’s Director of Sales & Marketing. “That’s why we’ve decided to strategically invest our world-leading ultra-low power wireless R&D expertise into contributing to the development of the OpenThread software stack while ensuring our nRF52840 multiprotocol SoC became Thread 1.1 Certified in addition to its full Bluetooth 5 certification. Home IoT product developers now have access to a powerful SoC, based on a proven architecture, that supports the most complex Bluetooth 5 and Thread IoT applications.”

About Dynamic Multiprotocol

The nRF52840 SoC supports Bluetooth low energy, IEEE 802.15.4 (Thread), and other RF software protocols. Previously, Nordic’s nRF5 SDK for Thread implemented a switching solution for multiprotocol support of Bluetooth low energy and Thread. A switched solution for such support operates by disabling the operational protocol before activating the other protocol. The technique is simple to implement but is unable to support concurrent protocol operation.

The latest release of Nordic’s nRF5 SDK for Thread (version 0.10.0) addresses that downside by introducing a Dynamic Multiprotocol solution for concurrent operation of Bluetooth low energy (Nordic’s S140 v5 SoftDevice (Bluetooth low energy RF protocol stack)) and Thread (OpenThread protocol stack).

The Dynamic Multiprotocol ensures the radio hardware’s operational time is shared between the protocols – ensuring both remain connected. Transmitting and receiving data using one protocol does not interfere with the other link during concurrent support.

Nordic’s firmware automatically looks after the time-sharing between protocols. The developer is freed-up to code the Bluetooth low energy functionality of a multiprotocol application as if it was solely leveraging Bluetooth low energy, and the Thread part of the multiprotocol application in the same way.

The module allows OEMs to provide bi-directional wireless audio streaming between, for example, a smart TV, set-top box, sound box or sound bar, and a user’s Bluetooth 4.0 (and later) Android smartphone or tablet.

Once paired, the module allows remote audio streaming between the audio equipment and the user’s mobile device, enabling playback via wired or wireless headphones connected to the device, and ensuring the audio does not disturb anyone else in the room where the audio equipment is in operation.

Thanks to the Nordic nRF52832 SoC’s support for Bluetooth 5’s 2 Mbps physical layer (PHY), RFsen’s module can support high-bandwidth audio streaming via Bluetooth low energy, offering a 48KHz audio sampling rate (superior to CD quality) with much lower power consumption than Bluetooth audio solutions based on Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) technology.

Nordic’s nRF52832 Bluetooth low energy SoC, a member of Nordic’s sixth generation of ultra low power (ULP) wireless connectivity solutions, combines an 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 low energy 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 most important hardware features that convinced us to use Nordic’s nRF52832 SoC were the ARM M4F core and its memory resources,” says Neil Niu, RFsen Co-founder. “The fact that Nordic’s Bluetooth 5 stack was very stable was another key reason for the decision, combined with good and timely technical support from Nordic engineers.”
