31.1  Bgscan and Roaming 
To enable Bgscan and Roaming add 'bgscan="simple:10:-45:100" ' in the sta_settings.conf. 
31.1.1  Description 
wpa_supplicant behavior for background scanning can be specified by configuring a bgscan module. These modules are 
responsible for requesting background scans for the purpose of roaming within an ESS (i.e., within a single network block 
with all the APs using the same SSID). 
The bgscan parameter uses the below format: 
"<bgscan module name>:<module parameters>" 
bgscan="simple:<short bgscan interval in seconds>:<signal strength threshold>: <long interval>"
