For users to select a proper SSID to configure connman WiFi, the
device needs to scan WiFi SSIDs, we don't have Python in our device's
small footprint, we cannot run connmanctl.
Are there any methods in connman to run WiFi scan? What alternative
open source (in C or C++) are you using for scanning WiFi SSID to find
your WiFi SSID name to configuring connman WiFi remotely?
