ScanResult capabilities interpretation

I want to analyze the capabilities string of a ScanResult. However, the names ther are grouped in up to four square brackets e.g.

[WPA-PSK-TKIP+CCMP][WPA2-PSK-TKIP-CCMP][WPS][ESS]


Is there some kind of documentation describing which bracket relates to what, considering that some names may apear in various brackets. It would be great if there was a list of all possible capabilities somewhere as well.

Answer

Last year there was a topic about this issue. You can find some help in this stackoverflow answer. In fact, there is little Android documentation about WiFi access points capabilities. Even in the offical Javadoc, regarding the signal level, the attribute level is only documented with:

The detected signal level in dBm. At least those are the units used by the TI driver.

It seems this is a very volatile information about the WiFi handling in Android.
