In this code why is it when i get to "node.restart()" it doesn't restart and start my wifi.lua? It just skips it 
Code: Select all
--file.open("init.lua","w")
--file.write(print("Wifi connect timed out."))
--file.close()
print("WIFI control")
-- put module in AP mode
wifi.setmode(wifi.SOFTAP)
print("ESP8266 mode is: " .. wifi.getmode())
cfg={}
-- Set the SSID of the module in AP mode and access password
cfg.ssid="ESP_STATION"
cfg.pwd="password"
if ssid and password then
print("ESP8266 SSID is: " .. cfg.ssid .. " and PASSWORD is: " .. cfg.password)
end
-- Now you should see an SSID wireless router named ESP_STATION when you scan for available WIFI networks
-- Lets connect to the module from a computer or mobile device. So, find the SSID and connect using the password selected
wifi.ap.config(cfg)
ap_mac = wifi.ap.getmac()
-- create a server on port 80 and wait for a connection, when a connection is coming in function c will be executed
sv=net.createServer(net.TCP,30)
sv:listen(80,function(c)
c:on("receive", function(c, pl)
-- print the payload pl received from the connection
print(pl)
print(string.len(pl))
-- wait until SSID comes back and parse the SSID and the password
print(string.match(pl,"GET"))
ssid_start,ssid_end=string.find(pl,"SSID=")
if ssid_start and ssid_end then
amper1_start, amper1_end =string.find(pl,"&", ssid_end+1)
if amper1_start and amper1_end then
http_start, http_end =string.find(pl,"HTTP/1.1", ssid_end+1)
if http_start and http_end then
ssid=string.sub(pl,ssid_end+1, amper1_start-1)
password=string.sub(pl,amper1_end+10, http_start-2)
print("ESP8266 connecting to SSID: " .. ssid .. " with PASSWORD: " .. password)
if ssid and password then
sv:close()
-- close the server and set the module to STATION mode
--wifi.setmode(wifi.STATIONAP)
wifi.setmode(wifi.STATION);
print("ESP8266 mode now is: " .. wifi.getmode())
