A week ago, a pull request of mine was merged into the dev096 branch that added a few features, including the one you are referring to.
if you use
http://frightanic.com/nodemcu-custom-build/ to build the dev096 branch the following additions should be available to you:
wifi.sta.config() :
Code: Select all/**
* 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
wifi.sta.disconnect()
*

wifi.sta.getconfig() :
Code: Select all/**
* wifi.sta.getconfig()
* Description:
* Get current Station configuration.
* Note: if bssid_set==1 STATION is configured to connect to specified BSSID
* if bssid_set==0 specified BSSID address is irrelevant.
* Syntax:
* ssid, pwd, bssid_set, bssid=wifi.sta.getconfig()
* Parameters:
* none
* Returns:
* SSID, Password, BSSID_set, BSSID
*/
wifi.sta.getap() :
Code: Select all/**
* wifi.sta.getap()
* Description:
* scan and get ap list as a lua table into callback function.
* Syntax:
* wifi.sta.getap(function(table))
* wifi.sta.getap(cfg, function(table))
* Parameters:
* cfg: table that contains scan configuration
* 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.getap(nil, function(T) for k,v in pairs(T) do print(k..":"..v) end end)
--scan configuration
scan_cfg={}
scan_cfg.ssid="myssid" --if set to nil, ssid is not filtered
scan_cfg.bssid="AA:AA:AA:AA:AA:AA" --if set to nil, MAC address is not filtered
scan_cfg.channel=0 --if set to nil, channel will default to 0(scans all channels), if set scan will be faster
scan_cfg.show_hidden=1 --if set to nil, show_hidden will default to 0
wifi.sta.getap(scan_cfg, function(T) for k,v in pairs(T) do print(k..":"..v) end end)
