Blynk server disconnection

potrei eleiminare il debug su monitor seriale…

sorry,

I could delete the serial monitor debug …

error detected: [19460] heartbeat timeout

why do you need delays ?

to be able to view the messages on LCD

Why? The written data isn’t going anywhere until cleared or overwritten… and you can use additional timers to send the viewable data in timeout timer segments.

Thanks Alexis for the answer and suggestions.
I tried to use your code does not actually disconnect from blynk but I can not display the data on the display.
I tried increasing the timer.setTimeout but without result.
… I’m studying the timer function to understand how to use it in this project …
at the moment the code works if I deactivate the LCD display …
thank you

could you please post your new formated code so I could help you?

Here it is, thanks Alexis…
in this way it does not disconnect from blynk, but on LCD I display only the first part related to the connection and the last water level …

Oh…my… :open_mouth: Why!!!

I don’t think you understand the concept of setting up a timer yet :stuck_out_tongue: all those go in the void setup() not in the loop where they are trying to run thousands of times a second.

AND, you have them all set to run simultaneously every 5 seconds… so even in the proper location… well, bad, very bad :stuck_out_tongue:

Stagger the timers accordingly so they do not try to run concurrent functions.

timer.setInterval must be in setup
you can’t use same timer.setInterval value

replace timer.setInterval(5000, sensoreDHT) with timer.setInterval(60000, sensoreDHT)
no need to get temperature every 5 secs

as functions are called by timer.setTimeout(1000L,…
you only need timer.setInterval(5000, Temper_Serra);

I don’t know if the void ads1115(){ … is correct I never use ads1115

as @GunnerTechTools said, you have to understand the concept of setting up the timers first. :wink:

Hi, I thank you for the suggestions I hope to be able to put them into practice.
… you will surely have understood that I am not a programmer …

I have made the suggested changes, below the new code, I hope I have understood and made the right changes.

… at the moment you do not disconnect anymore from blynk but the visualization on LCD is still fast …

I’m working on a scretch to learn how the Timer function works …

Hi Alexis with the changes you suggest in the Blynk app the DHT sensor data is lost!
… with the code I posted Blynk does not disconnect and the project works.
Only the LCD display is too fast and some data is not displayed.

I can not figure out how to manage the time of displaying individual information to be displayed on LCD …

DHT sensor is lost or failed ?

I saw that you have redundancy between void ads1115() and other void !

timer.setInterval(5000,ads1115);  



failed…

your code is very poorly structured :wink:
too many redundancies

Alexis, how could I fix it?
… I tried with the varibaili goblali but I can not make it work …
… if I exclude the display on the LCD, for how I thought it works even if it is badly written :slight_smile:
