This test app has Herald efficiency logging enabled by default to collect data that is helpful to debug the proximity detection.

• On Android, the log files are saved in the following external storage folder: /storage/emulated/0/Android/media/com.example.herald_flutter/Sensor so the adb tool from the Android SDK can be used to download those files to the computer:

$ adb -s <device> pull /storage/emulated/0/Android/media/com.example.herald_flutter/Sensor

• On iOS, go to "Devices and Emulators" in Xcode and then download the container for the installed HeraldTest-Flutter app. The log files will be inside the AppData/Documents subfolder inside the package's folder.

When the app starts make sure you accept all permissions within 15 seconds of launching.
