Bluetooth in Aviation

Bluetooth beacons are increasingly being used in the aviation industry to track pallets, unit load devices (ULDs) and audit temperature, humidity and shock levels.

Cargo Airports & Airline Service magazine has an article on the Bluetooth Revolution where it mentions ULD provider Unilode’s use of Bluetooth tags. Unilode is equipping its 125,000 ULDs with Bluetooth readers. This will take over two years but 80% should be fitted out within 18 months.

The most significant development recently in ULDs is the development of Bluetooth Low Energy tracking devices.

The article mentions how Unilode has been exploring the use of RFID over last 25-30 years. It says Bluetooth provides the solution to RFIDs limits of range, infrastructure cost and interference with aircraft systems. Bluetooth additionally allows monitoring of ambient shipment conditions, temperature sensitive cargo and shock sensitive cargo.

The key benefit of Bluetooth is knowing where units are, all the time, rather than relying on scanned updates. It provides for better utilisation of assets. This makes transport of freight easier, smoother and more efficient.

Real-time monitoring of assets allows the client to immediately know when assets are behind schedule, being routed inappropriately, or in poor conditions.

Bluetooth not only provides a scaleable and affordable way of tracking pallets and unit load devices but can also provide for tracking the status of smaller critical packages such as pharma and and cosmetics goods.

Here at BeaconZone, we have seen beacons used more for airline temperature sensing rather than tracking. For example, iB003N-SHT beacons are used by Qatar Airways to monitor the temperature of pre-flight cargo holding areas.

New Bluetooth Range Extender

Nordic Semiconductor, the manufacturer of the System on a Chip (SoC) inside most beacons, has announced a new Bluetooth Range Extender the nRF21540.

It’s an electronic component to be used at the SoC output to amplify the signal prior to being sent to the antenna. We expect this to be included in some future long range beacon designs. However, note that it uses more current (115 mA at +20 dBm) so is less suitable for use in coin-cell based battery powered designs.

Our ultra long range beacons already use RF amplifiers but from different component manufacturers. For example the iB003N-PA uses a RFAXIS X2401C chip to achieve up to 300m range. The FSC-BP109 also uses an output amplifier to reach up to 1000m on Android and 4000m on iOS but this beacon requires USB power.

How to Open Minew S1 Case

We have recently started stocking the Minew S1. Minew have a video showing how to change the battery:

If you are changing the batteries we recommend you use Lithium batteries, such as Energizer Lithium, rather than alkaline batteries. This gives a longer battery life, flatter decrease in voltage over time and better resilience under lower temperatures.

RTLS in Healthcare

There’s a new Mr Beacon video interview with HT Snowday, VP of Innovation and Technology Development at Midmark RTLS. Midmark and HT are formerly of Versus Technology who were acquired by Midmark in Aug 2018.

Midmark RTLS uses a combination of infra-red, 433Mhhz RF, WiFi and Bluetooth to provide tracking of healthcare assets, care givers and patients. It allows medical equipment to be located quickly, key things such as IV pumps to be effectively distributed (par levelling) and the location of care staff and patients to be controlled and monitored. The Bluetooth part of Midmark RTLS is used more for wayfinding using powered, static beacons to mark locations. Systems also allow for health workflow processes including self-rooming to reduce waiting and queuing for care.

Healthcare is increasingly being provided at outpatient rather than inpatient treatment. This is leading to more clinics and treatments centres and the need for technical sophistication to efficiently process patients.

No mention was given to other crucial healthcare usecases we have come across at BeaconZone such as tracking (and temperature) of valuable medicines, tracking porters, wheelchairs and wayfinding from the hospital limits to reception areas.

Physical Web App for Android

There’s a new Physical Web app for Android by the Physical Web Association. The app detects beacons advertising Eddystone URL.

The new app and the Physical Web Association take up the space left by Google abandoning the Physical Web. The association’s apps are unbranded so can be used by anyone to provide for information triggered by beacons.

The Physical Web Association aims to provide the universal apps, metadata services and support. Mr Beacon has a new interview with Agustin Musi and James Grant, founders of the Physical Web Association. It explains how the Association hopes to work with manufacturers to simplify the beacon setup experience. It also mentions opportunities to use Eddystone URLs to lead to progressive web apps to provide device control using web Bluetooth APIs. This was one of the original premises of Google’s ambitions for the physical web.

Unlike Google’s implementation, the Physical Web Association hopes to create a publisher-driven categorisation/ranking system and end user app settings to limit and filter when notifications are shown when beacons are detected in background.

Debugging Bluetooth on iOS

There’s a new article at Bluetooth.com that explains how to capture Bluetooth packets on iOS. The PacketLogger can decode all protocols defined by the Bluetooth Special Interest Group (SIG) and Apple, perform filtering, automatically highlight problems and search and export data.

This will work for both Core Location and Core Bluetooth. Core Location is using the iBeacon APIs while the lower level Core Bluetooth allows scanning and connection to any Bluetooth LE devices, not just beacons. It’s best to use the Core Location APIs and only use Core Bluetooth for more involved scenarios not supported by Core Location.

Note that Core Bluetooth, even though it’s lower level, can’t scan the iBeacon UUD, major and minor. Apple hides these values to force you to use Core Location.

There’s also an Apple session video from WWDC 2019 explaining Core Bluetooth and PacketLogger.

BeaconZone Shipping by UPS Courier

As of today we are all sending orders using UPS Standard and Express services rather than via post office tracked domestic and air mail. This is so as to improve international delivery times, make them more predictable and avoid problems due to the busy holiday period and impending postal strikes.

All UK orders now have next day delivery to business areas. International customers can now select between UPS Standard by road or UPS Express by air. Our delivery web page lists how UPS Standard delivery times vary by country. UPS Express arrives next business day to most European countries and the second business day to business areas in the US and Canada.

FIND Framework for Internal Navigation and Discovery

FIND is an open source indoor locating system for home automation, indoor local positioning and passive tracking. It uses your smartphone or laptop to pinpoint your position in your home or office with a location precision of below 10 sq ft.

FIND uses scanning of WiFi and Bluetooth:

FIND compiles these different signals can be compiled into a fingerprint which can be used to uniquely classify the current location of that device

Pushcut for iOS Updated

Pushcut, the HomeKit and workflow automation iOS app, has some updates that now allow iBeacon triggered in background. Delayed notifications and ‘do not repeat’ durations are also possible with iBeacon triggers.

Pushcut allows you to execute online actions and web requests in the background providing IFTTT triggers from an iBeacon.

Pushcut is listed in our Solutions Directory.
