Code: Select all
for i=1,1000,1 do print(i) end



leads to a hardware reset after 400 to 600 counts.

Yep, same here! Checked the heap space in the loop but that seems fine, remains the same.

I must tell, that i'm kinda away from being good at this thing, but can it be caused by the baud 9600 and buffer to print? i mean can u try doin it with a maybe a 10ms delays? Still the same result? (i know , it wont go for the next until the first printing is completed but ?? )

Hello,

I just flashed the latest version (18. Nov.).
But like the version before this line

Code: Select all
for i=1,1000,1 do print(i) end



leads to a hardware reset after 400 to 600 counts.

Is there a hint why this happens? Could it be the watchdog of the ESP8266?

Yes, same thing happens here, don't know why yet.
if I change the baud-rate to higher speed, it will output more, to cover 1000 output.
but

Code: Select allfor i=1,10000 do print(i) end

still cause reset.
and a forever loop

Code: Select alli=0 while(1) do i=i+1 end

also cause reset.

tmr.delay(10000) will cause even less output.

so, this may be because of system clock or watchdog or something related to time.
have no clue to solve it.

for now tmr.alarm(interval, 1, function do()) is recommended to do repeat job.

Code: Select all-- a simple telnet server
s=net.createServer(net.TCP)
s:listen(2323,function(c)
   con_std = c
   function s_output(str)
      if(con_std~=nil)
         then con_std:send(str)
      end
   end
   node.output(s_output, 0) -- re-direct output to function s_ouput.
   c:on("receive",function(c,l)
      node.input(l) -- works like pcall(loadstring(l)) but support multiple separate line
   end)
   c:on("disconnection",function(c)
      con_std = nil
      node.output(nil)  -- un-regist the redirect output function, output goes to serial
   end)
end)
