What is iBeacon Technology?

We sometimes get asked “What is iBeacon Technology?”. In terms of the beacon itself, iBeacon doesn’t imply much. The underlying Bluetooth does most of the hard work. iBeacon is only one of many possible formats of standard Bluetooth advertising.

The iBeacon advertising consists of three identifiers UUID, major and minor. We have an article explaining how these are usually set up.

The more useful functionality is in iOS itself. Apps can declare an interest in particular beacons and be triggered even when the app is not running. The triggering is usually used to cause a notification on the phone that the user can tap on to do more. If the app is already open, it can look for beacons and display appropriate app content.

Android may also trigger and scan for iBeacons but this is in the context of scanning for Bluetooth advertising as opposed to specific iBeacons.

How Does Using Beacons for Tracking Compare with the Use of RFID?

The main difference between beacons and RFID is the range. RFID only works up to 1m while beacons typically reach 50m to 100m, even more for specialist beacons. It’s also possible to get an indication of distance to the beacon whereas with RFID it’s just ‘seen’ or ‘not seen’.

RFID tags are less expensive than beacons. However, as the range of beacons is much larger, fewer readers are required thus compensating for the extra cost. It’s also possible to totally cover a much larger area.

How to Set Up iB003N Motion Triggered Broadcast?

The iB003N has an accelerometer that can be used to cause this beacon to only broadcast when it has been moved. This can be used to save battery power or as an alert that something, that shouldn’t move, has been moved. For example, we have a customer putting them on warehouse racking legs to detect when the forklift truck has crashed into them.

The iB003N manufacturer documentation on motion triggered broadcast is split over many sections of the user guide making understanding setup harder than it needs to be. In fact, it’s very simple. Connect to the beacon using the eBeacon app and set Service 0xFF70, Characteristic 0x2A80 (the beacon state) to 0x04. The beacon will now only transmit when moved.

Can Beacons Be Used on Aircraft?

We have had enquiries whether beacons can be used on aircraft. While there’s no specific guidance on beacons from aviation authorities, beacons transmit the same radio signals to other Bluetooth devices such as the FitBit, Android Wear, Apple Watch and Bluetooth headphones. These devices are classed as Personal Electronic Devices (PED).

The use of PEDs depends on the airline. Both the FAA and EASA have guidelines for the use of PEDs. Smart Luggage is No Longer Allowed.

How to Open the iB004N Case?

There’s a manufacturer-supplied video in our Ankhmaway technical information that shows how to open the iB004N. We haven’t been happy with this video for some time. Firstly, if you open the beacon as shown you are likely to crack the case. Secondly, it shows someone wielding what looks like a metal screwdriver that, given where it’s used, could easily short or damage the circuit board. Thirdly, if you snap it shut as shown, you will snap off the retaining lugs.

We have found that the best way to open the iB004N is with a plastic sharp edge such as a guitar pick. Push it down as shown, where there isn’t a retaining lug:

Lever and the case top pops off. Use a plastic tool to lever up the printed circuit board and replace the battery.

To put the lid back on, first place the lid side with the two lugs into the corresponding two holes in the side. Push the lid down and use the plastic sharp edge, in the same position as you used to take the lid off, to widen the case slightly as you push the lid right down. This way, the lug won’t snap off.
