I started a project where I want to detect objects with the value of the RSSI which can be found in the head of received beacon frames. According to IEEE, the measurement of the RSSI is vendor specific.
Where can I find any information about how the ESP8266 measures the Beacon RSSI? I look up the datasheets but couldn't find anything.
I wonder if there is any averaging using a vendor specific smoothing function? Is the value calculated linear or some kind of logarithmic? Is the value given in dBm?
How they calculate it is not known to me, but if you use a standard piece of hardware with a known method of calculating RSSI, and compare them side-by-side, you would know. The readings should not vary a whole lot, whatever the method.
