What interval should I use between each WiFi scan on Android?

Question

I need to perform Wifi scans at regular intervals. I am encountering a problem when the time interval is set to 1-2 seconds. It seems like I am not getting any ScanRes

Answer 1

From Android 8 and higher, the limit is 4 times in 2 minutes. So you could scan 4 times with 1 second of delay in between. But you would not get any further scan results for the next 126 seconds.

So the fastest interval where every scan is successful would be every 30 seconds.
