Connecting to low priority BSSIDs over high priority BSSIDs if they have better SNR

[Samitha Wijedasa]

Hi,

We have a high priority networks and a
low priority networks and we prefer to connect with high priority
ones using wpa_supplicant priority field, but in the case of high
priority networks having a low SNR we should consider connecting to
the low priority ones irrespective of the priority if the low
priority ones enjoy a better SNR.

In wpa_supplicant when priority is
enabled it always going for the high priority one even if the low
priority one may enjoy a higher SNR.

How can I modify wpa_supplicant to
cater this requirement. 

Thanks

Samitha
