Hi, how can i turn wifi station mode to the wifi acces point mode? İ want to connect to the esp8266 and then upload file with FtpServer.
-
Hi Kemran,
yes, It’s possible, I attach a simple sketch that do this work.
Respect the code from the article
FTP server on esp8266 and esp32
I add this part
// Connect to Wi-Fi network with SSID and password Serial.print("Setting AP (Access Point)…"); // Remove the password parameter, if you want the AP (Access Point) to be open WiFi.softAP(ssid, password); IPAddress IP = WiFi.softAPIP(); Serial.print("AP IP address: "); Serial.println(IP); -
Thank you for your reply Renzo, Did you remove this
WiFi.begin(ssid, password); Serial.println(""); // Wait for connection while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println(""); Serial.print("Connected to "); Serial.println(ssid); Serial.print("IP address: "); Serial.println(WiFi.localIP()); part of the code? Or just added access point part? Actually which part of code you removed and where actually added acces point part? -
-
İ copied this part from complete sketch. My question is that should i remove part which is i added above to add your acces point part?

Hi Renzo,
İ tested code which is above and there is a problem. İ uploded your code to my esp8266 nodemcu and then connected to the access point with my laptop. After all this wanted to connect with filezilla to the ftp server. Every time when i wanted to connect to the ftp server i got an errorors like “Connection closedby server” or “Could not connect to server”. 1.jpg is filizilla error and 2.jpg is serial monitor in esp8266 side. İ’am using esp8266 nodemcu V3 with 4MB flash. Do you have an idea ? İ actually stuck and dont know what to do. İ appreciate your reply.
Kemran D.

Hi Kemran,
It’s strange I repeat test with my WeMos D1 mini and works correctly

and try to give better power supply..Bye Renzo

Hi Renzo,
Congratulations on the work.I tried to run the sketch as an attachment (FTP via Access Point) but I couldn’t access the files and I got the following message:
Command is: PASV
Connection management set to passive
Listening at 0.0.0.0:50009
-M-L-S-D- -
Command is: MLSD
List of file!!Thank you for your attention.

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.
Bye Renzo

Hi
Has anyone managed to have Esp32 with Access point+FTP on SD card storage?
I have been using Esp32 with STA mode+FTP on SD card storage for a while, and it works perfectly both ways (upload, download), but now I need to do it in AP mode, and aparently there is a problem with fetching the SD file list after the connection is made, while on STA mode Filezilla prints this after connection:Status: Connecting to 192.168.1.107:21... Status: Connection established, waiting for welcome message... Status: Plain FTP is insecure. Please switch to FTP over TLS. Status: Logged in Status: Retrieving directory listing... Status: Directory listing of "/" successful Status: Retrieving directory listing of "/"... Status: Directory listing of "/" successfulOn the AP mode Filezilla prints this:

Also, I’m using arduino IDE 1.8.19 and esp32 board version 2.0.3.
STA and AP code attached.Can anyone give me a haned please, any tips are welcome.
Thank you.Cheers, Luís Pereira.

Hi,
First of all, thank you very much for your quick response.
The setLocalIp function placed before or after the server begin did not solve it, in the end I noticed that on FtpServer.cpp on linelocalIp = NET_CLASS.localIP();always set the local IP to 0.0.0.0, as if the setLocalIp made no diference…not sure why, doesn’t make sense. So I forced it, right afterlocalIp = NET_CLASS.localIP();I placedlocalIp=IPAddress (192, 168, 4, 1);and that solved it in a very dirty way.To make it STA and AP proof, In FtpServer.h I changed the function begin to:
begin( const char * _user, const char * _pass, bool AP=false ,const char * welcomeMessage = "Welcome to Simply FTP server");
, and in FtpServer.cpp changed:
localIp = NET_CLASS.localIP();toif(!AP)localIp = NET_CLASS.localIP();else localIp=WiFi.softAPIP();.This way the FTP server works on both STA and AP now, just passing true or false on the server.begin.
Surely the fix did not require all this trouble but I just couldn’t figure out why the setLocalIp wasn’t doing the job =\Anyway, it’s solved somehow, thank you very much for your help and libraries.
Cheers, Luís Pereira.

Dear Renzo; I’m using your last version of ftp library on esp32 with last arduino core and last stable arduino IDE. I’m having the same problem described here and on your github forum. my code, as regards wifi section, is similar to your last example here. ESP32 is in AP only mode. activating lib debug message, last part is exactly:
/**************************/
Command is: PASV
Connection management set to passive
Listening at 0.0.0.0:50009
-M-L-S-D-
/**************************/reading here, I understand that the problem was solved, but in order to have a client connection from filezilla on win10, I had to modify FtpServer.cpp at row 497 (of last available version on github), as:
/**************************/
.
.
.
//
// PASV – Passive Connection management
//
else if( CommandIs( “PASV” ))
{
data.stop();
dataServer.begin();
if (((((uint32_t) NET_CLASS.localIP()) & ((uint32_t) NET_CLASS.subnetMask())) ==
(((uint32_t) client.remoteIP()) & ((uint32_t) NET_CLASS.subnetMask()))) && (uint32_t)localIp <= 0) {
dataIp = NET_CLASS.softAPIP(); //NET_CLASS.localIP(); //<– LD
} else {
dataIp = localIp;
}
dataPort = pasvPort;
DEBUG_PRINTLN( F(” Connection management set to passive”) );
.
.
.
/**************************/replacing call to NET_CLASS.localIP() with a call to NET_CLASS.softAPIP()
with this replacement, the connection in fine&fast.
I tryed to use ftpSrv.setLocalIp(), with actual IP address, when the first wifi client connect to esp32 AP time after esp32 boot, but with no results. I have not tested the code with esp32 in STA mode.just for information, I had some trial with few android ftp client app, but with no luck. some app have trouble in entering PASV mode, some have trouble with SYST and another have trouble with file path (adding a strange ./ in the middle of the file path, just before file name. the app is working with a filezilla server).

Hi Renzo
yes, seems that the IP address the FTP class uses is wrong.As I wrote, my esp32 is used in AP mode only.
I configured the network with default IP address (192.168.4.1), gateway and subnet mask.
I have a web server on the esp32 that works normally.
I tryed to pass the right IP address to the ftp server, but with no results (ftpSrv.setLocalIp(softAPIP());I tryed just after the server begin and also just after the event of the first client is connected to esp32 AP WiFi. I tryed also passing to ftpSrv.setLocalIp() the corrected IP address as constant.
In my opinion the two function softAPIP() and localIP() act differently in AP mode and in STA mode.
The ftp server private variable localIp is initialized using localIP() and that (for some reasons) lead to
localIp == 0.0.0.0.Even if the code use
setLocalIp()after ftp begin, this is not used because at runtime, entering PASV mode, the code detect a 0.0.0.0 in localIp and try to obtain the correct IP, but always using localIP(), overwrinting user-assigned IP and obtaining again 0.0.0.0.At this point, using
softAPIP()instead, the ftp server can report the correct IP.In my opinion, a possible solution can be to act differently in STA mode and in AP mode, in a similar way as used in https://github.com/me-no-dev/ESPAsyncWebServer#using-filters; I used this feature in order to have two different web page accessing the esp32 from the AP or from the STA.
The two ‘filters’ are two functions that can be found in
https://github.com/me-no-dev/ESPAsyncWebServer/blob/master/src/WebServer.cpp at row 24

Hi Renzo. Thanks for the use of your library. I’m testing your Esp32 AP_FFAT sketch.
I’m a very basic coder so bear with me. I tried to modify the sketch to use SD card.
I’m able to connect to the server and directory listing says successful but the sd card is not displayed in the right hand window.
I can confirm sd card is working fine with another server in station mode. Do you have
a sketch for AP mode already configured for SD card as I figure my mod may not be up to par.
Thanks.Filezilla:
