ESP32 disconnected

Hi @JAVIER_MARIN, check this:

Multitasking... REAL multitasking with esp32

Hi fellows, I was digging on internet and fortunately found the way how to use both cores of esp32. Why? because when the device doesn’t get connected… It keeps trying to, and doesn’t do anything else, of course it can be sorted modifying the library, but always it will loss control time when tries to communicate, due it have to wait network answers or timeouts. So as this little asskicker has two cores, is perfect for this, because one can be dedicated to communicate (or try to from here to e…

And you can get rid of the header files just calling disableCore0WDT(); into setup.

To access the variables on both cores without issues i would use a semaphore with a boolean variable, and would use another set of variables, something like this:

Modbus core:

if (semaphore ==0){
//Dump the modbus variable into the extra variable set
semaphore = 1;
}

Thinger “thing”:

if (semaphore ==1){
// you can define the resources here, aiming to the extra var set
semaphore = 0;
}

In this way the modbus wont update the variables if the thinger process haven’t read the resources, and thinger wont read the resources if the modbus haven’t updated it, it’s a basic way to warantee that just one process will access the extra var set.

Try it and don’t stop improving your knowledge

Hope this helps.
