Does this work with a ESP32 that has flash encryption enabled?

I get an eternal loop if I just take the credentials line and put it into a credentials.h file and import it. Is this a user error?

code: output is: "..................."

#include <WiFi.h>
#include <WiFiClient.h>
#include <WebServer.h>
#include <ElegantOTA.h>
#include <credentials.h>

WebServer server(80);


void setup(void) {
  Serial.begin(115200);
  WiFi.mode(WIFI_STA);
  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());

  server.on("/", []() {
    server.send(200, "text/plain", "Hi! I am ESP32.");
  });

  ElegantOTA.begin(&server);    // Start ElegantOTA
  server.begin();
  Serial.println("HTTP server started");
}

void loop(void) {
  server.handleClient();
}

After upgrade from version 2.2.4 to 2.2.5 OTA not working.
Board is esp32 DOIT devkit v1. Server is responsing, but on the page is only ElegantOTA header, no checkbox firmware, no checkbox filesystem, no menu choose file.

after a successful update, a reboot button would be good.

Maybe not an issue !
The use of hardware timer blocks OTA update. This may solved by settings this timer in IRAM with IRAM_ATTR like in this example :

`int16_t tempsRestant = timeToGo;
hw_timer_t *Chrono_timer = NULL;
portMUX_TYPE timerChronoMux = portMUX_INITIALIZER_UNLOCKED;
bool ChronoIsRunning = false;
IRAM_ATTR void Chrono_decremente()
{
portENTER_CRITICAL_ISR(&timerChronoMux);
tempsRestant--;
portEXIT_CRITICAL_ISR(&timerChronoMux);
}

IRAM_ATTR hw_timer_t * Chrono_init(uint16_t time)
{
tempsRestant = time;
Chrono_timer = timerBegin(2, 80, true);
timerAttachInterrupt(Chrono_timer, &Chrono_decremente, true);
timerAlarmWrite(Chrono_timer, 1000000, true);
timerAlarmEnable(Chrono_timer);
return Chrono_timer;
}
`

Here is a really strange bug report. In Linux the OTA works fine. Android phones also work. In Windows 10, the OTA fails with a backtrace telling me:

Hi

Thank you for writing this. It is nicely done and "elegant".

However, I do have a suggestion. Can you please disable the writing to the Serial port. There is a message written to the Serial port when using ElegantOTA.

I cannot find where to disable this.

I do not believe that libraries should assume that the serial port is unused.

I have a few applications and projects that use the serial port for a variety of purposes, and having a message that I cannot disable coming from a library causes real issues for my applications/projects. I often start and stop the webserver service, and everytime it starts up I get this annoying message coming from ElegantOTA.

Thank you
Robert

Hi there!!!
I was really very excited about a month ago when installed the library. BUT... while working perfectly.... after a few uploads the browser became irresponsive. When I plug the ESP8266 on USB on Serial port there is a long error generated followed by a restart. What kind of mistake am I doing? Please Help me!!!

hi developer, is is possible to have at least some simple password checking , and user need to be key in correctly before allow to upload?

I have a spiffs *.bin file that I want to upload via elegantOTA, but an error occurs:

OTA Failed
Reason - Update error: ERROR[10]: Magic byte is wrong, not 0xE9

A few times I had to hit back, then reload OTA page, set filename and click upload again to get the transfer to complete successfully. (low wifi signal probably)

A retry button on a failed upload would be good. :)

I am receiving an Error on uploading my bin file. I use PlatformIO which creates a .pioenvs/nodemcuv2/firmware.bin file. After upload attempt I see OTA Failed Reason -. Just wondering if there is a way for me to see what the error is.

When i run "npm install", i am getting this error:

Could you add some functionality to allow us to skip the elegant web page where we already know the bin file path and name, a "batch" update mode. We can then can trigger the update when our application awakes from sleep and we know that it has an update waiting for it

Using IOS (14.2,) the progress bar immediately flashes to 99% on upload.
Presumably this is something Apple breaks, but can you modify the code to be IOS compatible?
Testing with an older IOS (9.3.6) its worse, and gets stuck on the ElegantOTA update screen (no choose file tabs etc) and you cannot choose files or update.

How to prevent that the files on the LittleFS gets deleted when uploading an ota?

Looking into some small modifications, I've found your local development option npm run serve. Which is really easy to setup and run.

However, upon opening the UI served locally I get an error that the JSON in /update/identity is invalid.

Opening that URL directly also shows the UI (HTML), instead of some JSON.

How would I work around that on the local development instance?

Hi,
I have a ESP32 system with a SD card that utilizes the FS.h.
This works perfectly and serves up 10 odd webpages from the SD card.

I'm having issues doing the following:

1. Firmware OTA updates.
2. General files system updates e.g. update SD card files htm, css, json etc.

How do I do this with the current system or modify the "AsyncElegantOTA.h" to add this support?

Hi, I can see a firmware update would be a new BIN file, what is the Filestsyem option for?
Can we update the SPIFFS file folder with this tool?

Hi - why do I only get the hello message when browsing to the IP address? I don't se any cool elegant interface?

Hi,
I am experimenting with ESP32

https://github.com/ayushsharma82/ElegantOTA/blob/master/examples/ESP32_Demo/ESP32_Demo.ino
and I wonder why, after one minute or so, the web page is no more available.

If I press reload the page is reloaded but no more than a minute .

After that if I reload I get an Err_Connection_Timed_Out .

If I reset the ESP32 everything comes back again ….
Regards,

JPD

After build for production in UI, what utility do you use to convert to hex to paste into elegantwebpage.h? In the dist folder, i have favicon, index.html and js. How do i merge these to the hex? THank you in advance!

As many others I discover that OTA ends with an error message when I do not have good WIFI signal strength. It stops with the message [HTTP ERROR] Bad Request in the update-Webpage.

I use it on an ESP32 and it runs a webserver with a small webpage to control a few switches and it has stable MQTT-Connection to Node-Red. So, generally, communication over the network is working reliable.

Looking at other comments, I feel that ELegantOTY is particularly demanding a very high network quality - As many other services work with much lower WIFI Signal strength (And I use many ESP32 at places with less than ideal signal strength without any problem except that I cant run OTA) I hope that there will be a way to correct this (maybe there is some error correction / checksum thing to da as I am sure that every means to avoid installing a corrupted binary is present :-)

Other than that I am very happy with ElegentOTA

With the versions 2.2.5 and 2.2.7 the ESP-01 and ESP-01s reset when access the web update ElegantOTA page.

I used the esp8266 demo as offered, only entering my wifi credentials.

Webserver loads fine. /update takes me to the update page. I navigate to the bin file for upload and click open.

The task bar progress to 100%, but then I get an [HTTP ERROR] Not Found message. The upload has not worked.

I am using a nodemcu 12F board with the latest arduino ide.

What have I done wrong? Thanks.

Most of the time, when I upgrade a device, I would want to reboot after successfully completing the upgrade.
A good idea? :)

Hi,

I'm using platformio (on VSC) and Win10 for programming of my device.
In my platformio.ini file I have placed the following code:
[env:WiFi]
upload_protocol = espota
upload_port = 10.100.8.60

When I try to build and upload, I get the following error:

Uploading .pio\build\WiFi\firmware.bin
14:18:41 [DEBUG]: Options: {'esp_ip': '10.100.8.60', 'host_ip': '0.0.0.0', 'esp_port': 3232, 'host_port': 48565, 'auth': '', 'image': '.pio\build\WiFi\firmware.bin', 'spiffs': False, 'debug': True, 'progress': True, 'timeout': 10}
14:18:41 [INFO]: Starting on 0.0.0.0:48565
14:18:41 [INFO]: Upload size: 1284432
Sending invitation to 10.100.8.60 ..........
14:18:41 [ERROR]: No response from the ESP
*** [upload] Error 1

If I browse to the device e.g. http://10.100.8.60/update, the ElegantOTA web page is displayed.

Any ideas on how to get this to work through the platformio environment?

I read somewhere on the RNT website that ElegantOTA overwrites the spiffs and Preferences (NVS) flash storage.
In platformio is there a way of limiting where ElegantOTA writes to?

Thanks,
Neil.

Hello, is it possible to disable or hide the filesystem update?

I use LittleFS for my projects so this is not useful for me.
Thanks.

How to edit Webpage?

how to change custom logo instead of ElegantOTA logo...Please help me

Thanks for the lib, it works magnificently right out of box, and what's more important — saves lots of time)

I've got a question about update process statuses callbacks.
E.g., i want to print some data on a screen after file upload is completed.

I went through the source files and found nothing suitable, am i missing something?

Thank you!

I was taking a look at the library files to see if it's possible to translate the texts and cahnge the logo, but the I have no ideia on how to changing the page that was made using some kind of encoding only with numbers.

So I ask, is there a way to edit it ?

By the way, what a amazing library, only one line to do all the job. I was looking for something like that for days.

Thanks for your very good job.

Sorry about my poor english.

If this could provide an AP mode initially to allow a user to set the Wifi credentials and .bin path, this firmware would be great to flash to an ESP prior to soldering (via a programming jig).

where is the buffer image locate in flash mem?
or I want to know how to make my bin file fix to the limition when I use thi lib? just as the arduino manual say?

Please share Elegant OTA Page if possible, & please also clear which option we have to choose in File2Raw
Gzip Compress
or
Use PROGMEM (Arduino)

Do you make the source for elegantWebpage.h available? It's hard to work with because it was minified. I want to be able to change some styles to match the rest of my project. I'd also like to pass the file name chosen by the user, for validity testing (if the user mixes up firmware and filesystem, OTA will happily try to program the wrong thing.) Check like this:

                int cmd = (filename.indexOf(F(".spiffs.bin")) > -1 ) ? U_SPIFFS : U_FLASH;
                if (cmd == U_FLASH && !(filename.indexOf(F(".esp32.bin")) > -1) ) {
                  debugMsgln(F("OTA bad filename"),1);
                  return; // wrong image for ESP32
                }

Even better would be to change the "accept:" on the file-input to reflect which file type the user selects.

Issue: Including ElegantOTA.h breaks cross-tab function calls.

To reproduce, use Arduino IDE 1.8.9 (although I doubt that the exact release matters). For a main sketch, use your example ElegantOTA/examples/ESP8266_Demo/ESP8266_Demo.ino
Immediately after the serial begin, add a call to a function in another tab, for example:

void setup(void) {
   Serial.begin(115200);
   setupXYZ();                  // Add this function call
   WiFi.mode(WIFI_STA);
   WiFi.begin(ssid, password);
   Serial.println("");
   ...

Now, add a tab (via the down arrow at the far right of the same line that contains the name of the main tab) , name it anything (without a dot extension), and declare a function in that tab:

void setupXYZ() {
   Serial.print("Setup of xyz complete.");
}

Now compile. The IDE will tell you that "setupXYZ() was not declared in this scope". In more complex call structures, it seems to break everything that is cross-tab, calling out each one as not declared.

Now comment out the "//#include <ElegantOTA.h>" statement (and the later begin statement). Compile again. This time it works. As it should in the Arduino IDE.

The SW is loaded correctly and shows 100% but it does not show the OTA success page

Hi! I noticed that the global variable ElegantOtaClass ElegantOTA is declared and implemented in the header file. Implementing such variable in the header basically forces the user to include it in the main ino file, and only there.

I would have expected the standard extern declaration + implementation in the .cpp for a global variable.

Is there a particular reason to do that? I would have considered this a simple oversight but I noticed that many arduino libraries are following this convention and I'm not a microcontroller developer. What is the benefit of forcing the user to include the library's header with a global object in the main file?

Thank you for your answer and your patience.

have long time using project with ElegantOTA, it works good on ver 2.2.4
Today have decided to add setID() functionality, and find out /update page became stuck, always spinning the circle under the page header. Micro is still working, no crash. Have removed setID() - /update works again.
btw, have updated to newer versions, esp8266 crashed disregarding with no setID() or without, seems like it is another bug.

Have left my project with old 2.2.4 version without setID().
:-(

Hello sir, The example code works properly, but when I append that code in my code, the update sticks mid way. Size of my bin file is 3,92,752 bytes. Is there any size limit to use Elegant OTA?

Hello
Could it be possible to upload overwrite add a single file to spiffs
Or upload add multiple files without a spiffs bin erase replace
Without erasing other files

Wpuld be usefull to me

Hello,

if i make a update with OTA my saved WIFI-Data will be erased. How i can prevend it?

Hello,

Thank you for your great job!

I found an issue.

I'm with 2.2.6.

I set ID and password on the /update page with this line : AsyncElegantOTA.begin(&server, "admin", "admin"); // Start ElegantOTA

When I flash with the new firmware the update is not set. If I remove the ID and flash, it's working fine.

Thank you for your support. :)

Hi there!

Thanks for this promising lib but in my case, i need to do ota through async web server and on AP mode only.
No wifi STA enabled on ESP32.
And in header we can see only ESP8266 management. So can we use it on ESP32?

hi,

I've tried to follow the example on this link on my wroom 32 dev board , however after uploading its continue to crash with the following result

Will this work on the esp32 chips?

Hi!
I have several devices locally that runs ElegantOTA, but I always have to think twice that I'm looking at the correct update page for the correct device.
What do you think about showing the hostname on the update page or some other String identifier that can be provided at setup of ElegantOTA?

It's really confusing for users with multiple ESP8266s as the ElegantOTA looks same on every module.

To overcome this, I will add a unique identifier to the ElegantOTA webpage which would by default point to the ESP Chip ID or if user wants to modify it then there would a function for it.
