Bluetooth Sensors for Analysing Sports

Nordic Semiconductor has a recent article by Petter Myhre Jun on Wireless Solutions Take Sports Tracking to New Level.

Bluetooth Sports Sensor
SpoSeNs 2.0 Professional Wearable

Petter talks about how location and movement sensors can be used to take athletic measurements for monitoring, analysis and performance improvement. He describes the SpoSeNs 2.0 Professional Wearable built round Nordic Semiconductor’s nRF52840 SoC.

However, many types of sports measurement can be implemented using off the shelf sensors. Standard beacons can be used for locating and Bluetooth sensors with accelerometers used for finer measurement of movement.

It’s also possible to measure heart rate that can lead into health related applications. We previously worked on Ultimate Sport Service’s heart rate tracking project. Ultimate Sport provide running race timing solutions. The heart rate tracking project allows Ultimate Sport to collect and display the real-time heart rates of a group of runners.

BeaconZone was a key part in succeeding with our custom heart rate tracking project. From assessing potential challenges in the Bluetooth framework on iOS and Android to evaluating hardware possibilities, we got valuable and accurate advice. The project was delivered on time and we are confident we will be working together again in the future.

Improving Factory Productivity in the Age of Covid-19

Beaconzone founder, Simon Judge, has posted a new article on Linked on Improving Factory Productivity in the Age of Covid-19. It takes a look at how factories are needing to scale up (or down) while, at the same time, maintaining social distancing.

Digitising manual production lines provides visibility through the use of contact-less measurement that can be used to improve productivity. The article explains how to get started.

Q2 Nordic Wireless Quarter Magazine

Nordic, the manufacturer of the System on a Chip (SoC) in many beacons, has published the latest issue of Wireless Quarter Magazine. It showcases the many uses of Nordic SoCs.

Wireless Quarter Magazone

This issue has a special feature on how Nordic powered devices are helping the fight against Covid. This includes smart thermometers, smart pulse oximeters, smart soap dispensers, improved cleaning of VR headsets and social distancing/contact tracing solutions. Of social distancing solutions the magazine says:

Technology is needed to enforce social distancing. Bluetooth LE wearables are emerging as one of the most promising workplace solutions

There’s also product news such as Lynxemi’s vibration and temperature sensor platform for predictive maintenance and the Carv Bluetooth LE sensor ski training solution. The magazine also includes an article on ‘STEAM’ (science, technology, engineering, the arts, and mathematics) and how the MICRO:BIT is going global.

The Future of Theatre Using iBeacons

Theatre and performing arts are currently going through a crisis as theatres remain closed but are still experiencing ongoing costs with no income. Performers are juggling new jobs to make ends meet. In the UK alone there’s a projected £74bn drop in revenue for the creative industries and the loss of 400,000 jobs. There’s a growing realisation that the Covid pandemic is going to be with us for a long time. Even when there’s a vaccine, it will take a long time to manufacture, only provide for gradual vaccination and probably require seasonal re-vaccination much like flu.

With this in mind, once theatres are allowed to re-open, they will have to adapt to the new normal. Andrew Lloyd Webber’s pilot performances are leading the way with improvements in hygiene, social distancing, temperature testing, mandatory face masks and special anti-viral sprays.

The Grand Theatre in Blackpool has a new article on the Future of Theatre In A Digital World. It describes new innovations that will improve the customer journey as well as provide for more automated contact-less engagement required for coping with the Covid crisis.

The aim is to integrate all systems to improve the customer experience, raise more online reviews and gain customer feedback. This starts with smart booking of theatre tickets through smartphones, watches and home speakers. Tickets reside on your smartphone with associated useful information such as casting biographies, announcements, behind the scenes photos/videos, reviews, cast introductions, offers and vouchers. This will allow for faster returns and seating updates. eVouchers allow contactless use of entry gates, concession areas, car parking passes, public transport tickets and pre-paid taxis.

iBeacon Theatre Bar Congestion

Bluetooth iBeacons allow for location based:

  • Checking in
  • Provision of information such as waiting times, best bars to head for and where to go for personal or accessibility assistance
  • Offering of vouchers based on previous spending habits
  • Messaging to advise turning down phone when seated, that might even be done automatically
  • When seated, promoting of upcoming productions with one click booking

Some of these things are starting to happen at theatres like the UK’s Blackpool Grand. The contact-less aspects are likely to be accelerated due to the Covid crisis.

New AprilBrother Beacons in Stock

We have five new AprilBrother models in stock:

The new EEK-N supports iBeacon, Eddystone and is the first beacon we have stocked that supports the Bluetooth LE Line protocol.

The USB Beacon 306 is one of the few USB beacon that have an external antenna that provides for a longer range up to 100m.

The ABN05 is the smallest wearable iBeacon we have seen with a size of 28.5mm x 28.5mm x 9mm.

The Road Stud is the first rugged cats-eye type beacon. It can withstand a weight of up to 10 tons. It isn’t restricted to use on roads and can instead be used in rough situations, for example, tracking construction site toolboxes.

4 Ways Beacons are Being Used to Fight the Covid Pandemic

  • Staff Locating – While our BeaconRTLS™ was previously mainly used in factories and warehouses, it is now being used more to determine the location of staff and occupancy of buildings. What might have seemed to be an invasion of privacy is now seen as something desirable to help ensure the safety of workers and audit compliance to industry-specific guidelines.
  • Social Distancing – Stand alone social distancing devices and tracking systems are helping companies get back to work and stay open.
  • Lone Working – There has been an increase in the use of beacons providing touch-free ‘check-in’ for workers and for SOS.
  • Cafes and Restaurants – Beacons are increasingly being used to identify tables for use in app-based ordering of food.

Farm Management with Bluetooth Sensors

There’s new research by the Universities of Salento Italy and Panamericana Mexico on the Development of Sensors-Based Agri-Food Traceability System Remotely Managed by a Software Platform for Optimized Farm Management.

It demonstrates the use of IoT to revolutionise farming. A system was implemented to provide for:

  • Optimum water and fertiliser use
  • Better quality and yield of crops
  • Increased safety
  • Reduction in production costs
  • Reduction in negative impacts on the health and environment
  • Smart traceability

Sensors allow calibration of irrigation and fertilisation based on crop type, growth phase, soil and environmental conditions. The traceability allows monitoring of the movements of food products from the field, through storage to end consumers.

Bluetooth LE sensor tags are used for monitoring conditions during storage and transportation so as to assess freshness, integrity, as well as to provide for traceability.

The system enables enables management strategies that anticipate or delay crop collection, fine tuning the irrigation/fertilisation timing based on customers’ requests. This allows farmers to achieve economic benefits and reduce agri-food waste.

Bluetooth Standards Pros and Cons

Here at BeaconZone we create solutions based on products that use Bluetooth LE. The Bluetooth standards are created and maintained by the Bluetooth SIG. This post briefly explores the advantages and disadvantages of such standards and the opportunities and risks of going off-piste using 3rd party wireless standards.

The main advantage of the Bluetooth LE standard is interoperability. We can use beacons, sensor beacons, smartphones, gateways, single board computers such as the Raspberry Pi, laptops and desktops in solutions and be sure they can communicate using Bluetooth LE. More specifically, we can use the Bluetooth APIs on these platforms and they speak a common language and ‘just work’. Bluetooth has also recently introduced standards on top of the Bluetooth LE standard that provide for mesh networking and angle based location.

The Bluetooth LE standard has caused the ecosystem of System on a Chip (SoC) vendors such as Texas Instruments, Nordic Semiconductor and Dialog Semiconductor to create inexpensive sub-systems and SDKs that simplify implementing new products based on the standards. This, in turn, has created a large variety of devices that can talk to each other even though they use hardware from different vendors. The variety of devices has increased competition, keeping device prices down.

The problem with standards is that they evolve very slowly and might not be optimal for specific situations. This creates an opportunity for 3rd parties to create alternative wireless solutions such as Ultra Wideband (UWB) devices, custom mesh networking and custom location schemes that can provide better performance in aspects such as accuracy, physical range and battery life. These custom products cost more because they are more involved to create/manufacture and their unique features can command a higher price. However, there’s the risk that if/when the companies producing these products go out of business, your solution will become end-of-life with no second sourcing. This is a particular risk when the product involves some sort of software as a service (SAAS), irrespective of standards.

Choosing a wireless technology for your solution involves a trade off between performance, cost and risk. It’s wise to first seek a standards-based and stand-alone (not SAAS) approach and only deviate if you find what you need to do isn’t served by available solutions.

New Bluetooth Beacons

We have two new beacons in stock:

The S1 is a USB beacon advertising iBeacon, Eddystone UID and Eddystone URL.

The H1 is a waterproof, rechargeable wristband beacon advertising iBeacon, Eddystone UID and Eddystone URL. It also has an accelerometer that can be used to provide for motion triggered broadcast. The front has a capacitive button that can be used to turn on/off or to only advertise when the button is pressed.

Both have the rare facility to send custom Bluetooth LE advertising that some customers use when they don’t want their beacons to show up other systems.
