print("Author: openthings@163.com. copyright&GPL V2.")
print("Last modified 2014-11-19. V0.2")
print("Wicon Server starting ......")

function startServer()
   print("Wifi AP connected. Wicon IP:")
   print(wifi.sta.getip())
   sv=net.createServer(net.TCP)
   sv:listen(8080,   function(conn)
      print("Wifi console connected.")

      node.output(s_output,1)

      conn:on("receive", function(conn, pl)

tmr.alarm(1000, 1, function()

Great job.

- Wed Nov 19, 2014 4:39 am #2893 I'm struggling here.

I made sure I understood the startup file - by first simply announcing my name... great - works. And I understand that one needs to delete the file and start again to update it - that's fine.

I also know how to set the thing into WIFI mode... and os I wrote this startup file - sadly it shows 0.0.0.0 BEFORE and 0,0,0,0 AFTER. I can think of no way to use this stand-alone - if you can't set up the wifi on powerup ???

file.remove("init.lua")
file.open("init.lua","w")
file.writeline([[print("Petes Tester 3")]])
file.writeline([[print(wifi.sta.getip()) ]])
file.writeline([[wifi.setmode(wifi.STATION)]])
file.writeline([[wifi.sta.config("loft-east","xxxxxxxx")]])
file.writeline([[print(wifi.sta.getip()) ]])
file.close()

- Wed Nov 19, 2014 5:10 am #2895 Hello,

Is it possible to read and write to the SRAM and port adresses with the current LUA version?
Or is the memory module mentioned in the LUA manual 5.1 necessary?

Background is that I would like to access the ADC (analogue digital converter) of ESP8266 CPU.
