Description

Hello,
You are writing that the WiFi.RSSI() does return a value in dBm.

https://www.arduino.cc/en/Reference/WiFiRSSI
> Returns
>
> long : the current RSSI /Received Signal Strength in dBm

According to the specification the RSSI value is only a relative value, comparable to a dBm value but not the same. The relation between the dBm values for a specific RSSI do change between different vendors.

Please could you clarify this?
Does the Arduino API really return a dBm value for the WiFi.RSSI() call?

Thanks in advance.

Bye
Rainer

Research direction

Start with the WiFi.RSSI() documentation at https://www.arduino.cc/en/Reference/WiFiRSSI and verify whether the returned value is truly calibrated in dBm or only a relative RSSI value. Done means the page accurately describes the unit and the clarification requested in the issue is reflected in the documentation.
