No RSSI measurements in the range between -50 and -80 dBm are available for AP1, AP3, AP5. Please try increasing the RSSI range for calibration in global settings for maps, or clear "Calibrate heat maps" to use predictive heat maps instead.

we are using 30 minutes scan. Do you mean "data collecting" maybe the device was in power saving mode?

[samantha_lynn]

You've got the background scan enabled to run when you have clients connected, but not when clients in power save mode are connected:

BGSCAN allow=enabled; BGSCAN during voice=disabled; BGSCAN interval=30 minutes;

BGSCAN with client=enabled; BGSCAN with PS client=disabled;

You've also changed the background scan time period to run every 30 minutes instead of the default 10 minute interval, just something to keep in mind.

background scans has been enabled since the AP was there. I do see lots of your APs having the missed scanning.

[samantha_lynn]

Thank you, you can see that we're missing a majority of the background scans:

Number of BGSCAN=13482; Number of BGSCAN requested=43903; Number of BGSCAN missed=30420;

Number of BGSCAN=90; Number of BGSCAN requested=22833; Number of BGSCAN missed=22742;

And these are required to fill in that data you're looking at. Would it be possible to enable background scans while clients in power save mode are connected? You would see these seeings in the Radio Profiles of the APs.
