There are currently known issues with core location being populated by the Arrow receiver. 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.
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, 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 Pr , 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:
