Is there a way to get an early, low confidence result from Coarse Relocalization?

Question

I'm developing a mobile app that uses Azure Spatial Anchors to determine visitors' position in a museum. There is understandably a delay between when a Watcher is started and when anchors are found. I was hoping that there would be a way to get a list of "likely spatial anchors" from the watcher. This would allow the app to estimate what gallery the visitor is in, and provide general location information while waiting for true relocalization. Then when anchors actually load, the app will know exactly which exhibit the visitor is standing at. Is this possible? Thanks in advance.

hi @Bill Jackson . with current ASA implementation, that is not possible. https://learn.microsoft.com/en-us/azure/spatial-anchors/concepts/coarse-reloc#platform-availability summarizes the availability of the sensor data. If you are targeting Android/iOS, you are limited by each platform and phone sensors. On Android, starting with API level 28, Wi-Fi scans are throttled to four calls every 2 minutes. On iOS, you should have in mind energy efficiency.
to summarize, this is platform dependent. you might want to consider using BLE beacons placed through museum.
