I use a ESP32-Wroom-32D custom board and I'm unable to connect to the FTP service because the directory "/" is not found. This confuses the FTP client and it disconnects (Cyberduck 7.10.2)

FS& gfs = LITTLEFS;

setup() {
...
ftp.addUser("admin", "admin");
ftp.addFilesystem("FS", &gfs);
ftp.begin();
}

loop() {
ftp.handle();
...
}

Also the windows command line tool can't open the root directory (so it seems not a client issue). Other directories work:
C:>ftp -d 192.168.178.118
Verbindung mit 192.168.178.118 wurde hergestellt.

Unfortunately the library does not compile for ESP8266.
I suppose the difference is in filesystem classes for two platforms. Apparently, nothing can be done here in simple ways.

Hi,

Thanks for your wonderful FTP server.
I was testing with ESP32 module (38 pin, Chip is ESP32-D0WDQ6 (revision v1.0)), ESP Arduino 2.0.10, and the latest ESP-FTP-Server-Lib.
Either using WinSCP or Filezilla, files can be uploaded or downloaded successfully without error notifications.

However, for unknown reasons some files are actually not completely transferred, as indicated by the size is less than the original file.
This is an example file:
https://drive.google.com/file/d/1bdaU4GCI2FMhASfk7SkDdKOKvaTC2E6O/view?usp=sharing

The original size is 573,825 bytes. But when it is uploaded to the SD Card of ESP32 FTP server, it becomes 573.440 bytes.
So the file becomes defective, and cannot be opened properly.

What may I have done wrong? Thanks for your guidance.

Hi,

*** [.pio\build\esp32cam\src\main.cpp.o] Error 1

Hello,

This library is so simple and functional, the only difficulty is that I'm using sdFat instead of the default SD that comes with ESP32 in Arduino. This is mostly to permit support for long filenames.

The line ftp.addFilesystem("SD", &SD); on the example is therefore not accepted as argument.

How would it be possible to add support for sdFat?

Many thanks in advance.

Hi,
I like the integration and your ftp server.
Unfortunately, I try to connect to the server on the ESP32, the use put to put the file on the server. The file is afterwards present on the SD card, but it has 0 Bytes.

Any help appreciated, I would really like to integrate it into my project.

Program I use:

#if defined(ESP32)
#include <SD.h>
#include <WiFi.h>
#elif defined(ESP8266)
#include <ESP8266WiFi.h>
#include <FS.h>
#endif

#include "ESP-FTP-Server-Lib.h"
#include "FTPFilesystem.h"

#define WIFI_SSID     "net"
#define WIFI_PASSWORD "pw"

#define FTP_USER     "ftp"
#define FTP_PASSWORD "ftp"

#ifndef UNIT_TEST
FTPServer ftp;

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

  
  
  if (!SD.begin(5)) {
    Serial.println("SD Card Mount Failed");
  }


  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
  while (WiFi.status() != WL_CONNECTED) {

Hello!
I am very like your library. Thank you very much! It is very useful and flexible. It is good work
I suggest to include in the library some additional commands. It is OPTS, NOOP, FEAT and MLSD. I have made some code for it and add several lines to your file FTPConnection.cpp (See attached). I have already tested the corrected code for ESP32 and it does work.

FTPConnection.zip
MLSD.zip

Hello Peter,

Great library! Installed it on an Olimex ESP32 Gateway.
Running now on WiFi going to move it to RJ45/Ethernet.

Do you have any idea when you would expect version 1.0 for the passive mode

Regards

Bart

Add MLSD command

how to change FTP buf size?

Hello,

Thank for your library! I've used it in previous projects and it works like a charm.

However, building for ESP (using Arduino framework) generates some warning and an error.

This is my compilation output:

I have tried to run the sample in VSC with ESP32 S2 and I receive the following error:

what is wrong?

Hi,
I’m using the ftp-server with 2 file systems in parallel, LittleFS and SD.
Everything works as expected. Thanks for your great contribution.

Question:
Is there a way to retrieve some status information about the ftp transfer from inside the ESP program? For instance the program needs to react on "New connection" resp. "Connection close". But info about transfer completion would also be useful.

Do you have any hint?

Thanks in advance

Appreciate the library trying to get it working but receiving compile errors below:

I compiled your example on ESP8266 with Platform IO as is. SPIFFS was built and uploaded. My FTP client connects successfully. But on a "ls"-command the server crashes with reboot in file NLST.h around line 27 in statement

File f = dir.openNextFile();

with

Any idea?

hi i am on an mac an use filzilla and the examplesketch on esp32 without sd

• it connects and i see my stored file inside spiffs folder
• when i try to download an empty file is downloaded (it shows in filezilla that the file shouldnt be empty)
• filzilla ask me to overwirte the empty file and then its still empty

what am i missing ? is there a permission in the esp32 code i can activate?
or are the filzilla setttings wrong?

i kindly appreciate your help

hi.

Thanks for the good code.

Are you planning on using AsyncTcp(async server)?

HI,

Like to try your library but get on ESP32 a link error:
undefined reference to `fs::FileImpl::getNextFileName(bool*)'
collect2.exe: error: ld returned 1 exit status
*** [.pio\build\esp32dev\firmware.elf] Error 1

Any idea?

Thanx Bart

First of all: Thanks a lot! It works really super stable and is very fast in the upload compared to other solutions.

The issue I have:
If the files contain spaces (or other non-standard characeters) the file won't be created on the filesystem with this name.
Changing the charset to force UTF8 or something else does not help.
With spaces it only takes the first part to the first space (file completely fine).
With special characters (like "ö" or "ß" or so) it does not work at all.
In the other direction (Download from FTP server) the same thing, but It fails in both cases.

Also creating folders with spaces has the same issue (will only create the part before the first space).

Is there a fix or workaround already available?

I'm using the ES32 with the SDMMCFS.

Configuration: Windows 10, Visual Studio Code 1.71.2, Platform ESP8266 4.0.1

Good morning to Austria!

I'd like to use this nice FTP-Client but I fail ....
Using your original example test.cpp, exchange credentials for my network access and my FTP-Server, build and upload it in a ESP8266. After correctly connecting to my network I start the FTP-Server and want to establish a session with this client. Then:

Do you have any idea what I can improve to make it run?

Thank you in advance
Andree

Dear developer, good Afternoon.

First, thank you for sharing your library.

I'd like to contribute with an issue report.

I've been using your library for connecting an ESP32 to FileZilla and I've found an issue that possibly regard internal CWD command.

The context is an application written in PlatformIO, using FreeRTOS. The setup() function calls:
`
...

servidorFTP.addUser(FTP_user, FTP_psw);

// servidorFTP.setFilesystem(&SD);

// servidorFTP.setFilesystem(&SPIFFS);

servidorFTP.addFilesystem("SD", &SD);

servidorFTP.addFilesystem("SPIFFS", &SPIFFS);

servidorFTP.begin();

...
`

When connecting through FileZilla, connection and access to ESP32 look fine, like this:
`
New Connection from 192.168.5.107:58471

USER base

PASS dados

CWD /SD

TYPE I

PASV

500 Unknown command

PORT 192,168,5,107,228,140

MLSD
`

And I can access, for example, "/SD" folder

But then, when I try to access some subfolder, the command is received in ESP32 like that:
`
CWD /SD/Teste05

[E][vfs_api.cpp:64] open(): /sd/SD/Teste05 does not exist
`

And FileZilla reports that this directory doesn't exist:

Would this be a failure, or should I fix something in my code?
Thank you.
Regards, Ciro Bruno.
