probeWifiPassive
Probes passive Wi-Fi capabilities via WifiManager without scanning networks.
Reports Wi-Fi enabled/state, supported bands (5/6/60 GHz depending on API level), Wi-Fi Direct support and (Android 12+) the driver country code.
Privacy: reads only radio capabilities and state, not SSIDs or scan results, so no location/nearby-devices permission is required. Contributes to hardware fingerprinting.
Return
Map of probe keys to Wi-Fi capability values.
Parameters
context
Context used to obtain the application-scoped WifiManager.
