Wireless MCUs are Bluetooth Mesh Certified

Cypress Semiconductor has announced its single-chip solutions for the Internet of Things (IoT) are Bluetooth mesh connectivity certified by the Bluetooth Special Interest Group (SIG) to a consumer product. LEDVANCE announced the market’s first Bluetooth mesh qualified LED lighting products, which leverage Cypress’ Bluetooth mesh technology. Three Cypress wireless combo chips and the latest version of its Wireless Internet Connectivity for Embedded Devices (WICED) software development kit (SDK) support Bluetooth connectivity with mesh networking capability. Cypress’ solutions enable a low-cost, low-power mesh network of devices that can communicate with each other–and with smartphones, tablets and voice-controlled home assistants–via simple, secure and ubiquitous Bluetooth connectivity.

Previously, users needed to be in the immediate vicinity of a Bluetooth device to control it without an added hub. With Bluetooth mesh networking technology, the devices within the network can communicate with each other to easily provide coverage throughout even the largest homes, allowing users to conveniently control all of the devices via apps on their smartphones and tablets.

Market research firm ABI Research forecasts there will be more than 57 million Bluetooth smart lightbulbs by 2021. Cypress’ CYW20719, CYW20706, and CYW20735 Bluetooth and Bluetooth Low Energy (BLE) combo solutions and CYW43569 and CYW43570 Wi-Fi and Bluetooth combo solutions offer fully compliant Bluetooth mesh. Cypress also offers Bluetooth mesh certified modules and an evaluation kit. The solutions share a common, widely-deployed Bluetooth stack and are supported in version 6.1 of Cypress’ all-inclusive WICED SDK, which streamlines the integration of wireless technologies for developers of smart home lighting and appliances, as well as healthcare applications.

BLE ICs Boast -105 dBm Sensitivity

Toshiba Electronic Devices & Storage has added two new devices to its lineup of ICs that are compliant with the Bluetooth low energy standard. The new TC35680FSG (featuring built-in flash memory) and TC35681FSG are well-suited to applications requiring long-range communication, including beacon tags, IoT devices and industrial equipment. Sample shipments will begin later this month.

The new communication ICs support the full spectrum of data rates required for the high-speed features—2M PHY and Coded PHY (500 kbps and 125 kbps)—found in the Bluetooth 5.0 standard. The new devices also deliver an industry-leading receiver sensitivity level of -105 dBm (at125k bps ) and a built-in high efficiency power amplifier in the transmission block that provides up to +8 dBm transmission power.

Bluetooth technology continues to evolve to meet wireless connectivity needs, and recent enhancements to the standard have been designed to increase Bluetooth’s functionality with the IoT. By adding Bluetooth 5.0-compliant ICs to its extensive lineup, Toshiba helps companies integrate Bluetooth low energy products into IoT devices and addresses the growing demand for high-throughput, long-range communications.

Based on an ARM Cortex-M0 processor, the new ICs incorporate a 256 KB Mask ROM to support the Bluetooth baseband process, and 144 KB of RAM for processing Bluetooth baseband, stack and data. Toshiba’s TC35680FSG and TC35681FSG also feature 18-port GPIOs as interfaces, which can be set to 2 channels each for SPIs, I2C, and UART. This allows for the structuring of systems that connect to various peripheral devices. These GPIOs can be set for a wakeup function, 4-channel PWM, 5-channel AD converter interfaces, an external amplifier control interface for long-range communication and more.

The TC35680FSG includes 128 KB of flash memory for storing user programs and various data in stand-alone operations, making it well-suited to a wide range of applications and removing the need for external non-volatile memory. This also lowers the part count, which reduces both the cost and mounting area.

The TC35681FSG, which does not include a built-in flash memory, operates in conjunction with an external non-volatile memory or host processor. A wide operating range of -40° to +125°C makes it suitable for applications exposed to high temperatures.

Massage Vest Uses PIC32

330 Freeman Lead Image

Controlled with an iOS App

These Cornell graduates designed a low-cost massage vest that pairs seamlessly with a custom iOS app. Using the Microchip PIC32 for its brains, the massage vest has sixteen vibration motors that the user can control to create the best massage possible.

By Harry Freeman, Megan Leszczynski and Gargi Ratnaparkhi

As technology continues to make its way into every aspect of our lives, we are increasingly bombarded with more information and given more tools to organize our busy days. For our final project in the Digital Design Using Microcontrollers class at Cornell University, we sought to build technology to help us slow down, enjoy the moment and appreciate our senses. With that in mind, we built a low-cost massage vest that pairs seamlessly with a custom iOS app. The massage vest embeds 16 vibration motors and users can control the vest to create the most comfortable and soothing massage possible. The user first provides their input through the iOS app, which allows for multiple input modes—including custom or preset. The iOS app communicates to a PIC32 microcontroller via a Bluetooth Low Energy (BLE) module and ultimately the PIC32 turns on the vibration motors to complete the user’s requests. A block diagram is shown in Figure 1. Throughout the massage, users can update their settings to adjust to their desires. The complete massage vest costs less than $100—competitive with mass produced massage vests.
330 Freeman Fig 1 for web
Massage vests have historically been used for both pleasure and therapeutic purposes. Several known iOS-controlled massage vests include the iMusic BodyRhythm from iCess Labs and the i-Massager from E-Tek—both presented at the Consumer Electronics Show (CES) in 2013. The former syncs a massage to music for the user’s enjoyment, while the latter provides Transcutaneous Electrical Nerve Stimulation (TENS) as a certified medical device to relieve chronic pain. A group of Cornell students also won an Innovation Award in 2013 from the Cornell University School of Electrical and Computer Engineering for a massage vest called the Sonic Destressing Vest. The Sonic Destressing vest claimed to reduce the serum cortisol levels of its users, potentially reducing the risk of heart disease and depression—among many other chronic issues related to high serum cortisol levels. Those three vests motivated us to build a multi-purpose massage vest that could be extended to provide the particular features of those vests if desired—serving an existing base of users.

This article describes the details of how our massage vest worked so you can build one for yourself. First, we’ll discuss the hardware design that creates the comforting experience the user has with the vest. This will be followed by a discussion of the software that integrates the components together and provides a friendly user interface. Finally, we will conclude with testing and results. …

Wearables Drive Low Power Demands

320 Wearablese Lead Image for Web

MCUs & Analog ICs Meet Needs

Wearable devices put extreme demands on the embedded electronics that make them work. Devices spanning across the consumer, fitness and medical markets all need a mix of low-power, low-cost and high-speed processing.

By Jeff Child, Editor-in-Chief

Designers of new wearable, connected devices are struggling to extend battery life for next-generation products, while at the same time increasing functionality and performance in smaller form factors. These devices include a variety of products such as smartwatches, physical activity monitors, heart rate monitors, smart headphones and more. The microcontrollers embedded in these devices must blend extreme low power with high integration. Meanwhile, analog and power solutions for wearables must likewise be highly integrated while serving up low quiescent currents.

Modern wearable electronic devices all share some common requirements. They have an extremely low budget for power consumption,. They tend not to be suited for replaceable batteries and therefore must be rechargeable. They also usually require some kind of wireless connectivity. To meet those needs chip vendors—primarily from the microcontroller and analog markets—keep advancing solutions that consume extremely low levels of power and manage that power. This technology vendors are tasked to keep up with a wearable device market that IDC forecasts will experience a compound annual growth rate (CAGR) of 18.4% in 2020.

MCU and BLE Combo

Following all those trends at once is Cypress Semiconductor’s PSoC 6 BLE. In September the company made its public release of the PSoC 6 BLE Pioneer Kit and PSoC Creator Integrated Design Environment (IDE) software version 4.2 that enable designers to begin developing with the PSoC 6. The PSoC 6 BLE is has built-in Bluetooth Low Energy (BLE) wireless connectivity and integrated hardware-based security.

Photo 1 The PSoC BLE Pioneer Kit features a PSoC 63 MCU with BLE connectivity. The kit enables development of modern touch and gesture-based interfaces that are robust and reliable with a linear slider, touch buttons and proximity sensors based using Cypress’ CapSense capacitive-sensing technology.

According to Cypress, the company had more than 2,500 embedded engineer customers registering for the PSoC 6 BLE early adopter program in just a few months. Early adopters are using the flexible dual-core architecture of PSoC 6, using the ARM Cortex-M4 core as a host processor and the Cortex-M0+ core to manage peripheral functions such as capacitive sensing, BLE connectivity and sensor aggregation. Early adopter applications include wearables, personal medical devices, wireless speakers and more. Designers are also using the built-in security features in PSoC 6 to help guard against unwanted access to data.  …

Antenna Measurement Made Easy

For web Lacoste Lead Image

Covering the Basics

If you’re doing any kind of wireless communications application, that probably means including an antenna in your design. The science of antennas is complex. But here Robert shows how the task of measuring an antenna’s performance is less costly and exotic than you’d think.

By Robert Lacoste

Now that wireless communications is ubiquitous, chances are you’ll be using Bluetooth, Wi-Fi, cellular, LoRa, MiWi or other flavor of wireless interface in your next design. And that means including an antenna. Unfortunately, antenna design is not an easy topic. Even very experienced designers sometimes have had to wrestle with unexpected bad performances by their antennas. Case in point: Google “iPhone 4 antenna problem” and you will get more than 3 million web pages! In a nutshell, Apple tried to integrate a clever antenna in that model that was threaded around the phone. They didn’t anticipate that some users would put their fingers exactly where the antenna was the most sensitive to detuning. Was it a design flaw? Or a mistake by the users? It was hotly debated, but this so-called “Antennagate” probably had significant impact on Apple’s sales for a while.

I already devoted an article to antenna design and impedance matching (“The Darker Side: Antenna Basics”, Circuit Cellar 211, February 2008). Whether you include a standard antenna or design your own, you will never be sure it is working properly until you measure its actual performance. Of course, you could simply evaluate how far the system is working. But how do you go farther if the range is not enough? How do you figure out if the problem is coming from the receiver, the transmitter, propagation conditions or the antenna itself? My personal experience has been that the antenna is very often the culprit. With that in mind, it really is mandatory to measure whether or not an antenna is behaving correctly. Take a seat. This month, I will explain how to easily measure the actual performance of an antenna. You will see that the process is quite easy and that it won’t even need costly or exotic equipment.

SOME ANTENNA BASICS

Let’s start with some basics on antennas. First, all passive antennas have the same performance whether transmitting or receiving. For this article, I’ll consider the antenna as transmitting because that’s easier to measure. Let’s consider an antenna that we inject with a given radio frequency power Pconducted into its connector. Where will this power go? First off, impedance matching should be checked. If the impedance of the antenna is not well matched to the impedance of the power generator, then a part of the power will be reflected back to the generator. This will happen in particular when the transmit frequency is not equal to the resonant frequency of the antenna. In such a case, a part of Pconducted will be lost.  That is known as mismatch losses: Pavailable= Pconducted – MismatchLosses. While that itself is a very interesting subject, I have already discussed impedance matching in detail in my February 2008 article. I also devoted another article to a closely linked topic: standing waves. Standing waves appear when there is a mismatch. The article is “The Darker Side: Let’s play with standing waves” (Circuit Cellar 271, February 2013).

For the purpose of discussion here, I will for now assume that there isn’t any mismatching—and therefore no mismatch loss. …

Bluetooth SIG Adds Mesh Networking to BLE Ecosystem

The Bluetooth Special Interest Group (SIG) announced that the wireless connectivity global standard now supports mesh networking. This enables many-to-many (m:m) device communications and is optimized for creating large-scale device networks, ideally suited for building automation, sensor networks and smart home solutions where tens, hundreds, or thousands of devices need to reliably and securely communicate with one another.

According to the Bluetooth SIG, Bluetooth Low Energy (LE) enables short-burst wireless connections and supports multiple network topologies, now including a mesh topology for establishing many-to-many (m:m) device communications. This is an important evolution for Bluetooth technology, and one of the most anticipated features envisaged by the Bluetooth SIG promoters, anticipating Bluetooth 5 practical implementations.

With this update the typical point-to-point, star-based network topology evolves directly to a true mesh networking topology, paving the way for a wide range of applications that span from personal area network solutions all the way to an expanded range of connected devices, theoretically without physical limits.

One of the main benefits will be precisely in the area where until now only standard 802.11 Wi-Fi solutions were available, which is the smart home and smart buildings. With the combination of Bluetooth 5 and mesh networking technology, manufacturers will be able to surpass worries about coverage range, without compromising on the low-power requirements that are mandatory in battery operated devices. This enables the creation of “blanket” Bluetooth networking coverage, with devices connecting between themselves without the need for a central router. This allows effectively the creation of autonomous Bluetooth Wireless Local Area Networks, allowing devices to communicate locally. For example, sensors will be able to send messages to main devices, allowing the music to start playing in the living room, as soon as the user moves out of the room.

As the Bluetooth SIG highlights, mesh networking doesn’t require any special controllers or hub equipment, there is no single point of failure, and any Bluetooth control device will be able to remote control any point of the network. All this, with assured interoperability and without complexity, allowing users to acquire and add devices from any vendor that adopted the standard.

The potential of mesh networking also allows more complex commercial and industrial scenarios. Bluetooth mesh is optimized for creating large-scale device networks and is ideally suited for building automation, sensor network, asset tracking solutions. New control and automation systems, from lighting to heating/cooling to security, wireless sensor networks (WSN) for industrial applications, are some obvious candidates for  Bluetooth mesh networking technology.

Capable of supporting broadcast topology, Bluetooth LE became an attractive alternative for asset tracking over active RFID. The addition of mesh networking lifs Bluetooth LE range limitations and establishes the adoption of Bluetooth asset tracking solutions for use in larger and more complex building environments.

20170719164724_BluetoothMesh03Web

A unique full-stack approach that defines the low-level radio up to the high-level application layer, ensuring all aspects of the technology are fully specified for the updated specification. Comprehensive, multi-vendor interoperability testing is conducted during the specification development process, not after specification release, and Bluetooth SIG members can benefit of all the qualification tools and processes needed to ensure global, multi-vendor interoperability.

The Bluetooth mesh specification is now available to all members, allowing manufacturers to start prototyping products. The Bluetooth mesh networking specifications, as well as the tools required to qualify Bluetooth products with mesh networking support, are now available at the Bluetooth website. Bluetooth mesh networking operates on Bluetooth Low Energy (LE) and is compatible with core specification version 4.0 and higher.

Kickstarter to Build Solar Powered Robot for Weeding Gardens

Franklin Robotics has launched a Kickstarter to build Tertill: a solar-powered and weatherproof robot that weeds your garden every day. With Tertill, gardeners can now enjoy weed-free vegetable and flower gardens, without the monotony and frustration of weeding.  Organic gardeners can breathe easy and enjoy a weed-free, chemical-free garden all season long. Created by roboticist Joe Jones – inventor of the Roomba – Franklin Robotics’ Tertill is designed to live in your garden and take care of the weeding, come rain or shine.

7ede858cdeb5691b813f7e10ebf18afd_original

Tertill lives in your garden and prevents weeds from becoming established.  Using unique design elements and a variety of sensors, Tertill patrols the garden daily, avoiding plants and obstacles while looking for weeds to eliminate. Tertill has a very simple method of distinguishing weeds from plants: weeds are short, plants are tall. A plant tall enough to touch the front of Tertill’s shell activates a sensor that makes the robot turn away. A plant short enough to pass under Tertill’s shell, though, activates a different sensor that turns on the weed cutter.

2b912b55a874afdeb8e6e9ae9cf2ba26_original

Tertill gets its power from the sun. When there is sunlight—even on cloudy days—Tertill’s solar cell converts the light into electricity. The robot stores the energy in a battery. You don’t need to charge or replace Tertill’s battery. Tertill uses its stored power smartly—during cloudy stretches, when less power is available, it patrols for weeds less often. Tertill is more aggressive during periods with more sun. Fortunately, weeds grow more slowly when they have less light.
