Mmmm… It’s very strange, Arduino had told me that WiFiNINA of my MKR 1010 It’s the same of Arduino Uno Wifi Rev2, but now I’m quiete sure that It isn’t true.
I try to re-write to It and I put the answer here.

Hi,
that screenshot is only the last part. You must copy and paste in a txt file.

Hi,
and please add the compiling output also please.
Thanks Renzo

Hi Grant,
if you have some time, can you describe your experience with teensy?
I think a lot of people can need help.

Hi,
please add the information I had requested.

Hi,
i tried it now and it worked correctly.

Try to format SD again and write and read something before start server FTP.

Give me some other information like the console output of compiling time.

Hi Grant,
perfect.. if you need more help write here.

Hi jordan23,
only e22 has the repeater function, with e32 you must do It manually, a device that receive a message and resend It to another device.

Hi Dusan,
you can use this example.

And you must follow the instruction that you can find on this article
FTP server on esp8266 and esp32

It’s important that you change the configuration on FtpServerKey.h like so

#ifndef DEFAULT_FTP_SERVER_NETWORK_TYPE_ESP32
	#define DEFAULT_FTP_SERVER_NETWORK_TYPE_ESP32 	NETWORK_ESP32
	#define DEFAULT_STORAGE_TYPE_ESP32 STORAGE_SD
#endif

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

Bye Renzo
