Too many requests? #16

Closed ZJaume closed 1 year ago

ZJaume commented 1 year ago

Noticed that the app was doing requests to frequently. Location indicator shows up every 10-30 seconds while seated and not moving, so I guess scanned networks are barely changing. I'm using LocalNLPBackend in MicroG with location permission allowed always, Android 13, LineageOS4microg 20.0, "Use cell towers" enabled, "Use wifi locations" enabled, active mode off, active mode GPS timout 10.

This is a sample from the logcat grepping the app id:

Is this something expected?

Helium314 commented 1 year ago

A WiFi scan is started if WiFi locations are enabled in the settings (enabled by default), and

To me it looks like either you have GPS on, or you have some app frequently requesting network locations, or the microG requests locations by itself, though that is not expected.

You can check why a scan is started if you use the debug version. You should either get update() - NLP asking for location or onGpsChanged() - accuracy <accuracy value> before the scan (attempt)
