Nano 33 IoT authentication issues

[shelby315]

Having a bit of trouble getting this library to authenticate to FileZilla FTP server. Once the client.begin() command runs I get the following output from both that arduino and the FTP Server:

13:27:25.971 -> Started with address 192.168.1.228
13:27:26.110 -> FTP ERROR - FTPBasicAPI::checkResult USER arduino
13:27:26.110 -> FTP ERROR - FTPBasicAPI::checkResult 220 Please visit https://filezilla-project.org/

13:27:31.086 -> FTP ERROR - FTPBasicAPI::checkResult NLST /
13:27:31.086 -> FTP ERROR - FTPBasicAPI::checkResult 331 Please, specify the password.

13:27:32.108 -> FTP ERROR - FTPBasicAPI::checkResult QUIT
13:27:32.108 -> FTP ERROR - FTPBasicAPI::checkResult 530 Please log in with USER and PASS first.

Its connecting to the FTP Server, but for some reason it believes that I am not sending a password, which from the code below I clearly am. The password that I am using is the correct password as I am able to connect to the FTP site using the same credentials from other libraries and FTP clients.

I have also tried changing the FTP server to have no authentication, but still get the same error messages.

code:

#include <WiFiNINA.h>
#include "ArduinoFTPClient.h"

WiFiClient cmd;
WiFiClient data;
FTPClient client(cmd, data);


void setup() {
    Serial.begin(115200);

    // connect to WIFI
    WiFi.begin("", "");
    while (WiFi.status() != WL_CONNECTED) {
      delay(500);
      Serial.print(".");
    }

    IPAddress localAddress = WiFi.localIP();
    Serial.println();
    Serial.print("Started with address ");
    Serial.println(localAddress.toString());

    // optional logging
    FTPLogger::setOutput(Serial);
    //FTPLogger::setLogLevel(LOG_DEBUG);

    client.begin(IPAddress(192,168,1,246), "arduino", "arduino");

    delay(5000);
    // list files
    for (auto file : client.ls("/"))  {
        Serial.println(file.name());
    }
    
    // clenaup
    client.end();
}

void loop() {
}

Can you connect manually by typing user arduino and provide the result that you get
The same for password.
I need the return code numbers which indicate a success. Currently I do not expect to get a 220 for the user command.

It seems that your server is using different return codes then what I have seen so far.

I get the following from FileZilla FTP server when connecting with FileZilla client

Oh, I see - the Initial 220 Response is messing things up: I am expecting this only once and not twice

[pschatzmann]

I committed a correction: However I am not absolutely sure, if it will work.
I just ignore all the input after the first login success method.

Can you double check ?

I am now able to authenticate and get the directory listing.

Thanks so much for your support it is greatly appreciated.

Below are the responses from authenticating from the Arduino.
