@all
A new build of firmware has released.
add adc.read() api, to read adc value of esp8266, not tested.
add wifi.sta.getap() api, to get router list.
check the wiki for detail.

Excellent, thanks.

- Wed Nov 19, 2014 12:00 pm #2923 Your new code from this afternoon. I had to blow it a couple of times as it would not seem to work... then I uploaded my file to it and it reset..... and worked... everything was well,. I turned the power off then on 5 times - worked perfectly.

Then I sent my file to it again - which should have erased the two functions and replaced them - the only difference being a longer delay (2 seconds) before reading the IP address as it was getting 0.0.0.0... back to repeats and rebooting.

Perhaps when you remove files there's a problem??

Now it is just resetting over and over.

Here's is what is in now minus my password

file.remove("init.lua")
file.open("init.lua","w")
file.writeline([[print("Petes Tester 4")]])
file.writeline([[tmr.alarm(15000, 0, function() dofile("thelot.lua") end )]])
file.close()
file.remove("thelot.lua")
file.open("thelot.lua","w")
file.writeline([[print("Stopping timer")]])
file.writeline([[tmr.stop()]])
file.writeline([[tmr.delay(500000)]])
file.writeline([[print("creating function")]])
file.writeline([[connecttoap = function (ssid,pw)]])
file.writeline([[print(wifi.sta.getip())]])
file.writeline([[wifi.setmode(wifi.STATION)]])
file.writeline([[tmr.delay(500000)]])
file.writeline([[wifi.sta.config(ssid,pw)]])
file.writeline([[tmr.delay(2000000)]])
file.writeline([[print("Connected to ",ssid," as ",wifi.sta.getip())]])
file.writeline([[end]])
file.writeline([[print("Running function")]])
file.writeline([[connecttoap("loft-east","xxxxxxx")]])
file.writeline([[print("Done")]])
file.close()

- Wed Nov 19, 2014 12:22 pm #2924 I tried your code on my board and it works without error.
I uploade two times and still works.

The only difference is that in this line

Code: Select allfile.writeline([[tmr.alarm(15000, 0, function() dofile("thelot.lua") end )]])

There should be a space after dofile.

- Wed Nov 19, 2014 12:28 pm #2927 Ernie - I don't agree. That is a function call - I don't think there should be a space where you suggest. If it IS necessary surely that's a bug?

All -

I've done some more tests.

In each case I am blowing the BLANK file and then the nodemcu_512k.bin file just to be sure.

In each case after doing this.. If I send the file below to the unit.. it works... BUT the delay is too short to show the IP address.

When I say WORKS I mean one initial message and one run of the code.

There are TWO things wrong.

Firstly If I then RELOAD the file - subsequent powerup goes wrong - there is something wrong with your file.remove() command
Secondly if I try to change the time delay HERE...

file.writeline([[wifi.sta.config(ssid,pw)]])
file.writeline([[tmr.delay(500000)]])

from half a seconds to 2 seconds....

EITHER by making it longer OR using it 4 times..

i.e.

file.writeline([[wifi.sta.config(ssid,pw)]])
file.writeline([[tmr.delay(2000000)]])

or

file.writeline([[wifi.sta.config(ssid,pw)]])
file.writeline([[tmr.delay(500000)]])
file.writeline([[tmr.delay(500000)]])
file.writeline([[tmr.delay(500000)]])
file.writeline([[tmr.delay(500000)]])

Either way this FAILS and the unit ends up in a loop - Am I right in guessing this is some kind of WATCHDOG issue?

Is it possible to fix these two issues - we are SO CLOSE!!
