The Demise of Unsolicited Marketing Using Beacons

There’s a new article at DIGIDAY on how Apple’s new privacy features have further rattled the location-based ad market. The iOS location and Bluetooth permission changes have caused users to opt-out of marketing messages:

Right now opt-in rates to share data with apps when they’re not in use are often below 50% … Three years ago those opt-in rates were closer to 100%

80% of those users stopped all background tracking across their devices

Location Sciences

Google’s discontinuing support for Android Nearby notifications and Apple’s tightening of permissions have caused the demise of unsolicited marketing using beacons. This is understandable because unsolicited marketing is seen by end-users as intrusive and creepy.

However, the iOS and Android mechanisms are still there for more worthy applications such as visitor space usecases that need to provide location based information. For these types of application, there’s the need for good app onboarding explaining location and Bluetooth usage in order to provide the location-based information that the end-user is requiring.

While unsolicited marketing was the key benefit when iBeacon was first announced, the use of beacons has since diversified into less contentious and more practically useful areas such as real time locating (RTLS), IoT Sensing and insights through machine learning.

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.

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.

iBeacon App Development Companies

There are a large number of offshore development companies currently spamming social media, claiming to do iBeacon development. We recommend you do your due dilligence before engaging development as many like to say ‘yes’ to anything and it’s often companies such as ours that have to pick up the pieces.

Here’s are some things to consider when looking for an iBeacon app developer:

  • Can they give examples of iBeacon apps they have written?
  • Can they give you references to past work who you can talk to?
  • Do they release development versions regularly so you can test and gauge progress? If everything is released at the end, it’s likely you are going to end up disappointed.
  • Who will actually be doing the development? There can be intermediaries in the development ecosystem that confuse and compound communications problems. Right from the start, you need to be talking direct with the person who will be doing the development.
  • Do they really understand you? Many aren’t native English speakers and if you are getting misunderstandings during initial engagement, this doesn’t bode well for the development.
  • Have they provided constructive comments on your proposed app rather than just saying ‘yes’? Developers should be able to improve on your ideas so as to get the best out of iOS and Android.
  • Getting iBeacon apps through Apple approval can be difficult. Can they give you examples why and the possible mitigations?

App development is an area where cheapest isn’t usually the best. Compromised development will cost you in the longer term through late or aborted development, tricky problems, significant end user support, poor app reviews and difficulty adapting the apps in the future for future phones and new features.

Beaconzone was founded by app developers in 2015 after we had previously created several iBeacon art gallery apps. We have since written many more iBeacon and Bluetooth LE apps on iOS and Android.

nRF Connect Features

Nordic, the manufacturer of the System on a Chip (SoC) in most beacons, has a new blog post on Five Things You Didn’t Know About Nordic’s Mobile Development Apps. The post mentions less visible features of nRF Connect on iOS and Android. For example, you can get a useful RSSI graph by dragging the screen towards the right from the centre:

nRF Connect is the main app we recommend for testing beacons. iOS recently received a completely new version. nRF Connect also has macros that can speed up testing.

BeaconWalker Aids Solution Development

If you are developing a beacon solution it can be tricky to set up physical scenarios where beacons come and go. Peter Alt of Philadelphia Museum of Art has a useful iOS app called BeaconWalker that simulates a sequence of iBeacons with custom durations per beacon.

The Swift source code is also available on GitHub. While you are there also take a look at the museum’s mobile framework, a collection of utilities for caching data, iBeacon ranging and indoor navigation. There’s also framework demo that explains how the framework features work.

Completely New nRF Connect for iOS

As we have previously mentioned, nRF Connect is the the best app for detecting if a Bluetooth LE device such as a beacon is working. The Android version has always had more features than the iOS version but that is changing. nRF Connect for iOS has been completely re-written and now has a very pretty UI.

We still recommend using the Android rather than the iOS version because iOS apps can’t see Bluetooth MAC addresses due to some peculiar decisions made by people at Apple. Scanning also can’t see an iBeacon UUID, major and minor in the advertising. It’s more difficult to uniquely identify Bluetooth devices in apps such as nRF Connect on iOS than it is on Android.
