* wifi.sta.listap()

* wifi.sta.getap(function(table))
* wifi.sta.getap(format, function(table))
* wifi.sta.getap(cfg, function(table))
* wifi.sta.getap(cfg, format, function(table))
* Parameters:
* cfg: table that contains scan configuration
* Format:Select output table format.
* 0 for the old format (SSID : Authmode, RSSI, BSSID, Channel) (Default)
* 1 for the new format (BSSID : SSID, RSSI, Authmode, Channel)
* function(table): a callback function to receive ap table when scan is done
this function receive a table, the key is the ssid,
value is other info in format: authmode,rssi,bssid,channel
* Returns:
* nil
*
* Example:
--original function left intact to preserve backward compatibility
wifi.sta.getap(function(T) for k,v in pairs(T) do print(k..":"..v) end end)
--if no scan configuration is desired cfg can be set to nil or previous example can be used

/**
* wifi.sta.config()
* Description:
* Set current Station configuration.
* Note: If there are multiple APs with the same ssid, you can connect to a specific one by entering it's MAC address into the "bssid" field.
* Syntax:
* wifi.sta.getconfig(ssid, password) --Set STATION configuration, Auto-connect by default, Connects to any BSSID
* wifi.sta.getconfig(ssid, password, Auto_connect) --Set STATION configuration, Auto-connect(0 or 1), Connects to any BSSID
* wifi.sta.getconfig(ssid, password, bssid) --Set STATION configuration, Auto-connect by default, Connects to specific BSSID
* wifi.sta.getconfig(ssid, password, Auto_connect, bssid) --Set STATION configuration, Auto-connect(0 or 1), Connects to specific BSSID
* Parameters:
* ssid: string which is less than 32 bytes.
* Password: string which is less than 64 bytes.
* Auto_connect: 0 (disable Auto-connect) or 1 (to enable Auto-connect).
* bssid: MAC address of Access Point you would like to connect to.
* Returns:
* Nothing.
*
* Example:
--Connect to Access Point automatically when in range
wifi.sta.getconfig("myssid", "password")
--Connect to Access Point, User decides when to connect/disconnect to/from AP
wifi.sta.getconfig("myssid", "mypassword", 0)
wifi.sta.connect()
--do some wifi stuff
wifi.sta.disconnect()
--Connect to specific Access Point automatically when in range
wifi.sta.getconfig("myssid", "mypassword", "12:34:56:78:90:12")
--Connect to specific Access Point, User decides when to connect/disconnect to/from AP
wifi.sta.getconfig("myssid", "mypassword", 0)
wifi.sta.connect()
--do some wifi stuff
