It will be possible to sleep device the FW ? :] I want to make my home automation on Atmega328+nRf24, but the network library is still buggy. And then came ESP8266

Is nrf24 and arduino buggy ? You are wrong place: ) esp sdk is very bulgu more than arduino +nrf now : )
I am using atmega328 + 433mhz rf +nrf24 and enc24j80. Its more stable more than esp. Esp platform growing every day but now Its is a child. Maybe we can use without bug one day

I like ESP8266 and ESP8285 and ESP32

Code: Select all
for i=7,20007,17
do
   print(i,i/13)
end



This LUA program leads to a hardware reset on my ESP8266 (ESP-01).
I try it several times with the same result. What could be the reason?

I've added the scripts as attachment hope they'll help =)

I had a look at your scripts and converted them for (my) use of the serial console.

I saw in your video that you display the content of a file by 2 commands:
filename="filename.lua"
dofile("fileread.lua")

I tried using a function for a 1-liner that allows the filename as a parameter. This work, I like it!

I created the file functions.lua and uploaded it to the ESP

Code: Select all printfile = function (name)
 file.open(name)
  repeat
    line=file.readline()
    print(line)
  until not line
end

On the ESP I execute the file functions.lua once. After that I can use the command printfile("filename.lua") to display the contents of the file.

Code: Select all> dofile("functions.lua")
> printfile("functions.lua")
printfile = function (name)
  file.open(name)
  repeat
    line=file.readline()
    print(line)
  until not line
end
nil
>

Please note:
- I do not have to use seek to determine the end of file
- the last printed line = NIL, probably because the last line in the file is blank
- in this way you can extend the supported Lua commands as if they were built-in commands

Using this way of working I intend to:
- code all default functions I need in functions.lua. After dofile all functions are available by just typing the name of the function and the required variables.
- When all testing is done, and I am satisfied with the functions I upload the file functions.lua to init.lua to execute the file at boot time.
- for every additional lua file I code, the functions defined are available for use. As a kind of library.

Neat, huh!

I can't get work nrf24 network library, I want to sleep node parent node and if message arrive then send it to base, but the node sleeps . Because the limitation of 6 pipes in nrf24. I know about the deep sleep function, it's not problem for me. I want the radion turn off, then I can wake it by other MCU. But there is no AT command for sleep. I tried to compile IoT example, but after 2 days I get worked only ct-ng compiler.
