There are currently known issues with iOS Core Location being populated by external Bluetooth receivers that offer this feature. For this reason, Eos Positioning Systems (Eos) recommends Arrow receiver users on iPad or iPhone consider avoiding an iOS 11.x upgrade. We’ve filed a report with Apple and are awaiting a new version after 11.2.5. We have tested iOS 11.3 Beta 6 and can confirm that the issue has been fixed. There is no date yet published by Apple for the release of iOS 11.3.
After receiving a variety of inquiries about this issue, Eos wanted to clarify who should be concerned about the iOS upgrades.
Do you need to avoid the upgrade?
The problem introduced in iOS 11.x only affects apps that are reading the location service. Apps that support the Arrow directly — like Collector for ArcGIS, Futura, CartoPac, etc. — are not concerned and work well.
However, apps such as Survey123 (current version) that only read the device’s location will work on the first connection (in Eos Tools Pro, Map View menu, the coordinates under “Core Location” and “Eos Receiver” will be identical). On the next Bluetooth connection, the iOS device will not allow the Arrow to populate the Core Location unless iOS device is rebooted.
Eos will keep you alerted about your device upgrades and any known issues. Not sure if you can upgrade or not? Find your device on this chart to see if you can upgrade your operating system:
