This would be the case with drivers that use hostapd for AP mode<br>
MLME/SME processing.<br>

Talk to the driver maintainers or use another WLAN device.. This may not<br>
be easily doable with the device you are using here.<br>

It's not really specific to Android in any way, but to the architecture<br>
the WLAN design uses in the system. If Probe Request frames are<br>
processed in firmware, there is not much hostapd can do about it. Since<br>
information from Probe Request frames is needed to allow WPS to be<br>
implemented correctly, you may have some luck of at least receiving<br>
information (like WPS IE) from the received Probe Request frames, but<br>
this depends on the driver in question.<br>
