weird error message on SM's

Hi guys,

I dig out some old sm’s (P8 mostly) and when I test them, I get a message on the Sm that reads:

RSSI 2949 Slicing Value not calibrated

Radio Power Level RSSI, Slicing Value, and Power Level not calibrated. Power Level not available

But the SM conects to the AP with no problem…I can ping the ap and transfer data, but the error message does not go away.
These are 5.2 AP & SM; the SM in P8 and AP is P9 working on hardware Scheduling.

Any idea on what may be the problem??

have you tried factory default ?

upgrade of software…

you can try playing on

I’ve never tried it, check what the settings are on the P8’s that are working fine
