Hi Aras,
but you have an original Ender 3??
And this printer support my firmware???

Can you send me the specs, and if you know other printer that support the firmware please send me.

Thanks Renzo

Hi Aras,
the only feedback we can receive is OK because the communication protocol from MCU and MKS WiFi don’t have other response type except the one explained here

MKS WIFI for Makerbase Robin: communication protocol and Cura plugin – 3

But we can send It via text, I think about that soon.

Hi Moniteur,
please insert the sketch the sketch on this forum, and the key file with ftp configuration, we are going to check.
I try with the SD (as I can understand from serial output) with an esp32 and AndFTP and It’s work for me.

Hi Aras,
I think It’s a good idea.
Do you have in mind how to do the widget? Like an editor and send GCode in sequence.
or where to put this development? In the movement widget??

If you have some idea write here Thanks Renzo

Hi Moni,
in the screen seems there isn’t nothing strange, did you try to transfer data?

Hi Felanino,
I found an example about that for pcf8574, but I think you can reuse that for pcf8575 also.

Here an image of Arduino connection schema

Here the complete code

#include "Arduino.h"
#include "PCF8574.h"

const byte INTERRUPTED_PIN = 2;

// Function interrupt
void infraRedActive();

// Set i2c address
PCF8574 pcf8574List [] = { PCF8574(0x20, INTERRUPTED_PIN, infraRedActive), PCF8574(0x21, INTERRUPTED_PIN, infraRedActive) } ;

bool irActive = false;

int i = 0;
uint8_t val = -1;
const int pcf8574Count = 2;

void setup() {

  Serial.begin(9600);
  for ( i = 0; i < pcf8574Count ; i++) {
    // Set pinMode to OUTPUT
    pcf8574List[i].pinMode(P0, OUTPUT);
    pcf8574List[i].pinMode(P1, OUTPUT);
    pcf8574List[i].pinMode(P6, INPUT);
    pcf8574List[i].pinMode(P7, INPUT);

    Serial.print("Init pcf8574..." + i );
    if (pcf8574List[i].begin()) {
      Serial.println("PCF8574 INIT SUCCESS ");
    } else {
      Serial.println("PCF8574 INIT FAILED ");
    }
  }
}

void loop() {
  delay(500);
  doOperation(pcf8574List[0], 1);  
  doOperation(pcf8574List[1], 2);
  irActive = false;
}

void doOperation(PCF8574 pcf8574, int no) {
  pcf8574.digitalWrite(P0, LOW);
  if (irActive) {
    Serial.println(no);
    pcf8574.digitalWrite(P0, HIGH);
    pcf8574.digitalWrite(P1, LOW);
    val = pcf8574.digitalRead(P6);
    if (val == 0) {
      Serial.print("P6 ");
      Serial.println(val);
    }
    val = -1;
    val = pcf8574.digitalRead(P7);
    if (val == 0) {
      Serial.print("P7 ");
      Serial.println(val);
    }
    delay(1000);
    pcf8574.digitalWrite(P1, HIGH);
    val = -1;
  }
}

void infraRedActive() {
  //Serial.println("*");
  irActive = true;
}

Thanks to adarshkumarsingh83

Hi moniteur41,
to upload photo you can use 2 way, create an account or use service like Postimage .

Try to add
SPIFFS.format();
after begin phase.

Hi AuLeeFor,
you can find It in the first “tutorial” article about e32.
Ebyte LoRa E32 device for Arduino, esp32 or esp8266: specs and basic usage – Part 1

Hi r0vert,
sorry but the problem can be your network or the certificate, I don’t know how to help you better.
Bye Renzo

[Renzo Mischianti]

I think It’s permanent, but to be sure try to re-upload the NINA firmware from arduino ide and re-upload the certificate.
Bye Renzo

[Renzo Mischianti]

Hi,
the debug message say to us that the micro controller can’t communicate with google, so (if not work with hot spot also) probably there is a problem with the certificate you add to the device.

Try to update firmware and the add google.com to the list and request to upload the certificate with the button in the bottom of popup.

Bye Renzo

Hi PonyStyle,
I upload all the code and the precompiled firmare, you can get more information in the relative articles.
MKS WIFI for Makerbase Robin: communication protocol and Cura plugin – 3

Bye Renzo

[Renzo Mischianti]

Hi r0vert,
I try your sketch and It’s work without problem, I think there is some wrong in your network or your gmail account permission.
Try to enable debug on library and send me the result.
Bye Renzo

[Renzo Mischianti]

Hi,
arduino answer me, and the wifi Nina is the same.
So there aren’t additional problem respect my mkr 1010 that work with the library.

Can you write the exact code with xxx on password and other data without change anything else.. ( same breaket and “)

Bye Renzo

[Renzo Mischianti]

Hi r0vert,
theoretically It’s the same, but I write to Arduino to have more info, I write here when they give me a response.
Bye Renzo
