Unable to send to ftp server

[gr8rithic]

Hi, I am working with your library in esp32 dev module. The problem I am facing is I am unable to send a .log file through my esp32 but I am able to send it using filezilla software with the same file format. The problem is happening in this line ftpClient->ftpClientPut(). Can you help out will be helpful.

PS: I am able to send my data to node red ftp server but I am unable to send the data to another FTP server setup using the python script provided in this repo.

Node red package - https://flows.nodered.org/node/node-red-contrib-ftp-server

I am unable to send the data to another FTP server setup using the python script provided in this repo.

What is another FTP server setup?

I would like to clarify the issue.

From ESP32 to Node red ftp server: OK/NG?

From ESP32 to Python ftp server provided in this repo: OK/NG?

I am using this code to create a FTP server

import pyftpdlib.authorizers import pyftpdlib.handlers import pyftpdlib.servers import argparse import logging import os

from pyftpdlib.handlers import FTPHandler

class Handler(FTPHandler): def on_file_sent(self, file): logging.info("send file! {}".format(file)) self.ftp_send(file)

def on_file_received(self, file):
    logging.info("received file! {}".format(file))
    self.ftp_store(file)

logging.basicConfig(format='%(levelname)s:%(message)s', level=logging.INFO) parser = argparse.ArgumentParser() parser.add_argument('--user', default="ftpuser", help='ftp user name. default is user') parser.add_argument('--password', default="devmode", help='ftp user password. default is password') parser.add_argument('--port', default=2121, type=int, help='ftp port. default is 2121') parser.add_argument('--timeout', type=int, default=300, help='timeout for network operations in seconds. default is 300') parser.add_argument('--passive_ports', default='30000-30009', help='range of passive ports. default is 30000-30009') parser.add_argument('--keep_alive', type=int, default=60, help='keep-alive interval in seconds. default is 60') parser.add_argument('--passive_timeout', type=int, default=300, help='passive connection timeout in seconds. default is 300') args = parser.parse_args() logging.info("user={} {}".format(type(args.user), args.user)) logging.info("password={} {}".format(type(args.password), args.password)) logging.info("port={} {}".format(type(args.port), args.port))

authorizer = pyftpdlib.authorizers.DummyAuthorizer() authorizer.add_user(args.user, args.password, os.getcwd(), perm='elradfmw') handler = Handler handler.authorizer = authorizer handler.passive_ports = range(*map(int, args.passive_ports.split('-'))) # Set passive ports range handler.timeout = args.passive_timeout # Set passive timeout

server = pyftpdlib.servers.FTPServer(("0.0.0.0", args.port), handler) server.timeout = args.timeout # Set timeout server.keep_alive_timeout = args.keep_alive # Set keep-alive interval server.serve_forever()

The file I am trying to send is a log file which is stored in esp's spiffs storage

I am able to send data using filezilla but I am unable to send it using esp32 using this repo

Your python code have a bug.

class Handler(FTPHandler):
    def on_file_sent(self, file):
        logging.info("send file! {}".format(file))
        #self.ftp_send(file)

    def on_file_received(self, file):
        logging.info("received file! {}".format(file))
        #self.ftp_store(file)

    def on_file_sent(self, file):
        # do something when a file has been sent
        pass

    def on_file_received(self, file):
        # do something when a file has been received
        pass

It is still not working

I am able to connect and login to the ftp server but unable to send the data file

You have too little information. This is my logging. Please tell me what's different.

I will check and will let you know I have converted the espidf code to arduino-esp32 (v 2.0.14)will try uploading using espidf and let you know I have attached my logging

BTW - is there any limit on the size of data?

[nopnop2002]

How did you get this logging? Could you please elaborate on what you did to get this logging?

I don't understand your problem at all.

If there is a problem with my code, please point out the exact problem in the code.

I have converted the espidf code to arduino-esp32

This project is guaranteed to work with ESP-IDF. Operation with Arduino environment is not guaranteed.

I'll say again.

is there any limit on the size of data?

I don't think there are any restrictions.
