S6 WiFi doesn't continuously update RSSI value?

I’ve tried getting the value through API frame and ATDB but the value doesn’t change unless I reconnect to the network. Is it possible to poll the RSSI value with the S6?

Also, there’s no mention of RSSI PWM on P0 as in the S6B. Is there no PWM value for this module?

Not sure what ATDB is try ATLM works OK for me
