I’m teaching my Spider how to sniff out WAP, and one thing I’d like to do is show relative signal strength in mW. Unfortunately, the Redpine data sheet for the RS9110 [url]Silicon Labs is lacking that particular data point.
The Gadgeteer SDK doesn’t provide a max value for this property, either (can probably assume int.MaxValue)…?
I found [url]百度文库, which states that the RSSI property is a “absolute value of the RSSI information”.
In testing, this value increases inversely with WAP distance, so it’s probably safe to assume that it represents negative Dbm; not mW.
