Service for Cloud-based evaluation of Bluetooth Low Energy designs simplifies integration of Nordic products into larger systems making up the IoT

Nordic Semiconductor today announces that it has launched ‘nRF Connect for Cloud’, a free service for Cloud-based evaluation, test, and verification of Bluetooth® Low Energy (Bluetooth LE) designs employing Nordic’s nRF51 and nRF52 Series multiprotocol Bluetooth LE Systems-on-Chip (SoCs).

nRF Connect for Cloud features an intuitive workflow and offers much of the functionality of Nordic’s ‘nRF Connect for Desktop’ and ‘nRF Connect for Mobile’ which are popular applications used for building and developing Bluetooth LE products. nRF Connect for Cloud also supports an extensive range of standard Bluetooth services together with proprietary services such as nRF UART.

Operating with all popular browsers, nRF Connect for Cloud uses Web Bluetooth application programming interfaces (APIs) to push and extract data to and from the Cloud, enabling the developer to test and modify the behavior and performance of prototypes. By using the front-end and visualization features of nRF Connect for Cloud, historical data can be extracted from databases and analyzed in a browser. The product also allows engineers to monitor and interact with remote wireless Internet of Things (IoT) designs enabling the collaboration of geographically separate development teams on a single project.

nRF Connect for Cloud is supported by the nRF Gateway App available for iOS and Android-powered mobile devices. The nRF Gateway App enables Nordic Bluetooth LE devices to use a smartphone-enabled Internet gateway to convert Bluetooth LE messages to ReST/MQTT/IP protocols for Cloud interoperability.

The Gateway App communicates with the nRF Connect for Cloud back-end hosted on Amazon Web Services (AWS) and is based on Software as a Service (SaaS) components. By leveraging AWS industry-grade components, the app implements end-to-end data and device connectivity, guarantees reliability, and scales from a few to hundreds of Bluetooth LE devices.

nRF Connect for Cloud currently supports Bluetooth LE solutions but future versions will also support Nordic’s nRF91 Series low power, global multimode LTE-M/NB-IoT System-in-Package (SiP) for cellular IoT. Following Nordic’s established strategy of constant enhancements to its development tools, planned updates for the nRF Connect for Cloud will reinforce its position as an indispensable tool for wireless IoT development teams working with Nordic products.

“nRF Connect for Cloud is a great asset for the rapidly expanding number of development teams building distributed IoT systems that use Bluetooth and other wireless connectivity technologies to connect to the Cloud and back-end systems,” says John Leonard, Product Marketing Manager, Nordic Semiconductor. “The product shortens the previously time-consuming migration from device-to-smartphone to device-to-Cloud connectivity and simplifies integration of Nordic wireless products into the larger systems that make up the IoT.”

nRF Connect for Cloud works out-of-the-box with the Nordic Thingy:52 IoT Sensor Kit, Nordic nRF5 development kit (DK), and software development kit (SDK) examples. A quick-start guide is available from www.nrfcloud.com.

What are Ferrite Beads?

Ferrite beads are used as low pass filters to eliminate high frequency noise while allowing low frequency signals or DC current to pass through a circuit. The noise may come from any number of sources including high-frequency switching noise from a power-supply circuit or RF noise in an RF signal-isolation circuit that must be minimized to ensure both signal integrity and antenna efficiency.

Ferrite beads, whether chip or wirewound, are used to filter electromagnetic interference (EMI). You may be surprised to discover that wirewound ferrite beads provide a high magnitude of attenuation over a wide frequency range, whereas traditional thick-film chip ferrite beads have limited options for both attenuation and frequency range.

Wirewound Versus Traditional Chip

In addition to offering better attenuation and frequency performance than their chip counterparts, wirewound ferrite beads also provide lower DC resistance (DCR) and higher current ratings without core saturation, resulting in the highest possible performance in the smallest size.

Wirewound versus Traditional Chip

Coilcraft wirewound ferrite beads come in standard package sizes from 0201 (0603) to 1812 (4532), all providing extremely low DCR while maintaining high filtering impedance over the broadband frequency range. These features enhance the performance of the choke circuit while potentially reducing board space by replacing a larger chip ferrite bead with an equivalent, or higher-performing wirewound ferrite bead.

Figures 2 and 3 demonstrate how Coilcraft wirewound ferrite beads provide superior broadband performance compared to both low- and high-DCR chip ferrite beads. Figure 2 compares the Coilcraft 0402DF-12 wirewound ferrite bead to the lowest-DCR 0402-sized chip ferrite bead. The 0402DF offers higher impedance across the frequency range, providing a greater measure of filtering from 100 MHz and above. Compared to typical high-DCR chip ferrite beads, the Coilcraft wirewound ferrite bead maintains the same high frequency attenuation while providing higher current ratings and 40 percent better DCR.

Connected City

Connecting cities to the information age

Courtesy of u-blox : Connecting cities to the information age

Studies show that by 2020, cities will have nearly 1 billion smart meters and that 50 million street lights will be smart street lights. Let’s highlight the key market drivers fueling this Smart City application growth.

Sustainability

A preliminary requirement for a Smart City investment is sustainability. The technologies used to operate these cities must enable clean energy initiatives to create a greener, more environmentally‑friendly city that successfully meets energy, emission, and waste reduction goals. Examples include optimization of pickup routes in waste management, parking systems to reduce driving time in search for an available spot, emissions sensors, and street lighting solutions that respond to current environmental conditions.

Public safety

Ranging from traffic situation monitoring and responsiveness to improved lighting solutions and video surveillance at main intersections, public safety initiatives can lower crime and reduce traffic incidents.

Cost‑savings

By implementing wireless and positioning technologies, a Smart City enjoys many cost savings:

  • Long deployments — Smart City devices can be remotely monitored and receive critical security and firmware updates over the air (FOTA) long after they are installed, ensuring that the infrastructure remains safe as well as reducing cost and eliminating the need to update devices individually
  • Lower maintenance — Devices can be monitored remotely, reducing expenditures for maintenance workers that have to be sent out to visually inspect equipment or record utility meter data
  • Reduced energy expenditures — Smart City applications lower power consumption for municipalities. Examples include adaptive street lighting that can respond via sensors to environmental or traffic conditions and route optimizations for city vehicles
  • Reduced wear & tear — Data captured by Smart City technologies can be used to manage city assets more effectively when and where they are most needed
Bluetooth Low Energy and ANT+ heart rate monitor

Bluetooth Low Energy and ANT+ heart rate monitor platform allows OEMs to modify and rebrand advanced fitness and movement tracking wearables

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.

Balun Performance Metrics

There are many different types of baluns and the type of balun used in microwave RF designs depends on the bandwidth required, the operating frequency, and the physical architecture of the design. Most baluns usually contain two or more insulated copper wires twisted together and wound around or inside a core, magnetic or non-magnetic. The following metrics are key in considering balun design, application, and performance.

Key specifications in determining the type of balun for a specific application include:

  • > Frequency coverage
  • Phase Balance
  • Amplitude Balance
  • Common Mode Rejection Ratio
  • Impedance Ratio/Turns Ratio
  • Insertion and Return Loss
  • Balanced Port Isolation
  • DC/Ground Isolation
  • Group Delay Flatness

Phase Balance

An important performance criterion based on how close the balanced outputs are to having equal power and 180° phase, or balance, measured by how closely the inverted output is to 180° out of phase with the non-inverted output. The phase angle deviation from 180° is phase unbalance.

Amplitude Balance

This metric is determined by construction and line matching and is usually specified in dB. Amplitude balance indicates the match between output power magnitude, and the difference of these two magnitudes in dB is called amplitude unbalance.  Generally, 0.1 dB improvement in amplitude balance will improve the common-mode rejection ratio (CMRR) by the same amount as a 1° improvement in phase balance.

Common Mode Rejection Ratio (CMRR)

When two identical signals with identical phase are injected into the balanced ports of the balun, they will be either reflected or absorbed. CMRR, specified in dB, is the amount of attenuation this signal will experience from the balanced to unbalanced port. The vectorial addition of the two signals determines the CMRR which is dependent on the amplitude and phase balance of the balun.

Impedance Ratio/Turns Ratio:

The ratio of the unbalanced impedance to the balanced impedance usually stated as 1:n. This differential impedance is between the balanced signal lines and is twice the impedance between the signal lines and ground. Turn ratio in a flux coupled balun transformer, is the ratio of primary windings to secondary windings; the square of the turns ratio with a 1:2 turn ratio gives a 1:4 impedance ratio. Flux coupled transformers can be used to design high impedance ratio baluns.

Insertion and Return Loss

The lower the differential  insertion loss and higher the common mode return loss means more of the inserted signal power passes through the balun, and hence improved dynamic range, and less distortion of signals.  In an ideal balun without isolation, the common mode signal would be perfectly reflected, with a return loss of 0 dB, while the differential signal would pass through completely with a return loss of -∞.

Balanced Port Isolation

The insertion loss from one balanced port to the other as specified in dB. Most baluns do not offer high isolation because the even mode is reflected instead of being properly terminated with a resistive load. An exception is the 180° hybrid circuit where the even mode is output to a port that can be resistively terminated.
