I am also getting the same error (recvRetCommandFinished err). Getting this error wherever I am trying to write on any text box. Can you please help?

arduino code:

#include
//#include
int speed1=8;
unsigned long val;
float val1;
int speed2;

void setup() {
pinMode(8,INPUT);
Serial.begin(9600);

}

void loop() {

val =pulseIn(speed1,LOW);
Serial.println(val);
val1=val*0.000001;
Serial.println(val1,4);

int speed2=0.9375/val1;

Serial.println(speed2);
Serial.print(“SPEED.txt”);

delay(1000);
}

If you are getting output on serial monitor and not on nextion means there is something wrong in particular tag definition for text box. Check your code again.
Or send your code and nextion hmi file to me, i will try to help you out with the code..

I am getting the input on the digital pin of arduino and by using pulse in function I am calculating the time period of the pin being low.
And then I have a formula in which I placed that time value and the answer of the formula needs to be displayed on the nextion screen. I have used text box for that and programed according t that but I am not getting the value on the screen but getting on the serial monitor of arduino. So can you help me out. Thank you.

I watched the video and copied the code and download HMI ( had to change device to 5″)

Outputs are not changing state and I get the output window below. ( Not sure why I would be getting the multiple “err”‘s )

recvRetCommandFinished err
recvRetCommandFinished err
setup done
[1694:0,2,bt0]
Callback
ptr=1694
recvRetNumber err
