[ESP8266] ESP8266 LUA - Problem sending full data to server

Hi,
I need help with the code for ESP-12 written in LUA....
The ESP is supposed to work like this:
- AVR does all the reads/counts
- wakes up the ESP from sleep
- sends data via UART
- ESP sorts the data, sends it to the server and when it finishes it goes to sleep

The problem is that ESP doesn't want to send all the data-maximum 17 (last four missing) and there are 21 data (possibly more)
I don't know myself anymore if the ESP is too slow or if the code sucks?

init.lua


avr.lua


Thank you in advance for your help and best regards.

Is it the device you are sending data to that has the ability to receive individual data rather than the entire data set?

If it has such a possibility, then the data, instead of being sent to an array, i.e. RAM, can be written to a flash and then it is just a simple operation on strings and files

Unfortunately, but only single data can I send

Added after 3 [minutes]:

I don't know what's going on, but now it's like I only have a certain amount of time to send and then the ESP goes to sleep. It doesn't wait for all the data to be sent
Just wondering... maybe the watchdog is interrupting my sending because the task is taking too long? But how to stop it? (as long as he is the culprit)

You probably have the TimeOut set to 30s and do not close the session after sending.
Each session must be closed and reopened for the duration of the data send.

They think writing to and reading from files would take care of things here, but get rid of the AVR and connections via UART and large text arrays in the first place.

then instead of into an array


write to a file, each sensor on the next line and read in a loop through readln

And can you suggest how to do this?

I won't be able to get rid of it because it's supposed to do all the (rather large) work, and the ESP is supposed to sort and send the data on. PCB done, everything mastered, everything works just missing those last four data

first check what you have set in

node.dsleep()
rtctime.dsleep()
wifi.sleeptype()

Oh chickens... but you bombed with information

I don't have anything because I don't have it in the code.

I just use:

so that ESP goes to eternal sleep-AVR wakes it up.

You do not have the modules uploaded, but the functions are active all the time. I guess you have to compile new firmware for yourself

I use:
nodemcu_float_0.9.6-dev_20150704.bin

Here you have a quick program I wrote to retrieve data from flash memory line by line

This is how I retrieve the entire contents of the file that is in the ESP
let me know if you understand this code:

Somewhere I saw a page where you can "build" your firmware, but I can't find it now.

piotr411 wrote:

This is how I download the entire contents of the file as it is in the ESP

Such a small, silly question. What is this code supposed to be used for and why do I need it?

Honestly not really

http://nodemcu-build.com/

ESP has 12,12E,12F has 4MB of memory for data, a kind of "hard disk"
Results can be stored there and fragments can be downloaded so as not to occupy RAM
When there is not enough RAM, even the whole 4MB or 16MB for ESP 13 can be transferred with one variable and without occupying RAM

The program takes the data from the file in the ESP line by line and sends it to the tablet or other devices

Instead of creating an array as you have now done, write it to "disk"
This is what the code above is for

Got it... is HERE
but what should I mark?

This has already appealed to me, but I'm afraid I'm too thin for such "acrobatics"

You are quick as lightning in your replies and read my mind

SSL: false
modules: file,gpio,http,i2c,net,node,rtcfifo,rtcmem,rtctime,tmr,uart,wifi

in this configuration your program does not report problems after adding 10 variables, but every now and then it crashes for 2 minutes, something with the Timers you messed up

File operations are child's play in LUA
Almost identical to QBasic

Here you have everything beautifully described about files, including simple examples

I will build, upload and check

It only transmits 17 variables and doesn't want any more

For me it's secret knowledge, black magic and voodoo

Big exaggeration:)

it is really simple, no more complicated than the arrays you have already mastered

Added after 12 [minutes]:

See how simple it is:

You start by saying that you should create "some" file
let's call it TEST.txt



This program writes "Moisture sensor 1:89%" on the first line as if it were a piece of paper

Now the fun begins and what you need to know:)

"r": read mode (the default)
"w": write mode
"a": append mode
"r+": update mode, all previous data is preserved
"w+": update mode, all previous data is erased
"a+": append update mode, previous data is preserved, writing is only allowed at the end of file

That is, we used the write function "w" write
file.open("TEST.txt", "w" )

Now if you want to read 1 line in the TEST.txt file
then this is enough:



The variable a will contain the string Moisture sensor 1:89%

simple?

The next step is to add another line, delete the contents, set the cursor, etc.........

@piotr411 thanks for all the tips
