Welcome, I have a script on a website that when executed displays the value of $wyslij. On the NodeMc I have the program uploaded (via the Arduino IDE): After execution, it displays the result to me on the serial monitor. I would like to extract the value of $send that was sent. :idea: Can you...

this example should help you (use string.find and insert a constant element in $wyslij, e.g. $wyslij=result:XXXX, and in string.find you search for result:) Code: LuaLog in, to see the code

I changed this code a little bit but somehow it cuts off the name of the fan variable by one letter - I read it in this loop Code: C / C++Log in, to see the code Result on serial monitor code reading the downloaded data Code: C / C++Log in, to see the code

NodeMcu - how do I upload a variable from a web page to NodeMcu?

Welcome,

I have a script on a website that when executed displays the value of $wyslij.
Code: PHP
Log in, to see the code

On the NodeMc I have the program uploaded (via the Arduino IDE):
Code: C / C++
Log in, to see the code

After execution, it displays the result to me on the serial monitor.
Quote:

[HTTP] connection closed or file end.
[HTTP] begin...
[HTTP] GET...
[HTTP] GET... code: 200
8
deactivate

0

[HTTP] connection closed or file end.

I would like to extract the value of $send that was sent.
Can you help how to complete the program on NodeMcu.
