could just use python to change on the fly (thanks to co-worker for code)

import dbus
DBUS_PROP_IFACE = 'org.freedesktop.DBus.Properties'
WPA_OBJ = '/fi/w1/wpa_supplicant1'
WPA_IFACE = 'fi.w1.wpa_supplicant1'
bus = dbus.SystemBus()
proxy = bus.get_object(WPA_IFACE, WPA_OBJ)
wpas = dbus.Interface(proxy, DBUS_PROP_IFACE)
debug_level = wpas.Get(WPA_IFACE, "DebugLevel")
print(debug_level)
debug_level = wpas.Set(WPA_IFACE, "DebugLevel", "info")
debug_level = wpas.Get(WPA_IFACE, "DebugLevel")
print(debug_level)
What if just run sudo wpa_cli log_level debug
?
May be too late. In the latest wpa_supplicant, you have to enable logging by building it with DEBUG_LOG_FILE=y in the .config file to enable the -f flag.
I think most people will now use systemctl to stop and start services and wpa_cli to enumerate any reconfigurations. Also, in many cases, I find reloading dhcpcd useful for forcing the wifi device to start a session. For anyone else arriving here in 2018 via Google...
