I just flashStart Here example on NodeMCU. The date is 1/1/1970 no matter if I set what timezone or interval.

When I add NTP.begin() in void setup() the date is correct and if I change timezone (IP ADDRESS/admin.html -> NTP settings) then it go back to 1970.

kindly include an asynchronous client also for outbound requests

I'm trying to build on the UserConfigExample using the REST callback. I have been able to create userConfig.json and userConfig.html files. When invoked the userConfig.html file displays the correct data from the json file. When I try to modify the data the url updates with the arguments showing the new data values. However the REST callback does not see these arguments. The callback always prints zero arguments.

I am a complete newB when it comes to web programming and not much better with C++. Given an example I can usually figure out how to tailor it to my needs. This example assumes greater web knowledge than I possess!

I have attempted to attach my userConfig.html file (as a text file) for reference.

Here's my callback code:

void  callbackREST(AsyncWebServerRequest *request)
{
  //its possible to test the url and do different things, 
  //test you rest URL
  if (request->url() == "/rest/userConfig")
  {
   printf("# args = %d\n", request->args());  // always returns zero arguments
   if (request->args() > 0)  // Save Settings
    {
        String data;
        Serial.println("Updating user configuration parameters");
        for (uint8_t i = 0; i < request->args(); i++) {
            if (request->argName(i) == "mqttUser") {
                data = ESPHTTPServer.urldecode(request->arg(i));
                printf("mqttUser = %s\n", data.c_str());
                ESPHTTPServer.save_user_config("mqttUser", data);
                continue;
            }
            if (request->argName(i) == "mqttPass") {
                data = ESPHTTPServer.urldecode(request->arg(i));
                printf("mqttPass = %s\n", data.c_str());
                ESPHTTPServer.save_user_config("mqttUser", data);
                continue;
            }
            /*if (request->argName(i) == "tz") {
                _config.timezone = request->arg(i).toInt();
                NTP.setTimeZone(_config.timezone / 10);
                continue;
            }
            if (request->argName(i) == "dst") {

                continue;

        }
    }

    //contruct and send and desired repsonse
    // get sample data from json file
    String values = "mqttUser|"+ mqttUser +"|input\n";
    values += "mqttPass|"+ mqttPass +"|input\n";
    request->send(200, "text/plain", values);
    Serial.println(values);
    values = "";

  } else if (request->url() == "/rest/user") 
  {
    String data = "data1";

Hello,

after installing Arduino IDE with all the libraries to a new PC I could not compile the demo application any more. I have discovered that the problem is in the latest version of ESPAsyncWebServer. I have dowloaded the bab5457 version of it as of Jan 22, 2017 and after the hack with time.h the project compiles without errors.

Regards

Jiri

i installed all the libraries and try to compile the example but i get the error below.
Am i missing something ??

thanks in advance

Hi, I like to test the callback example and it compiles well and the upload to a esp8266-12F works fine. I start the esp to config, that works also. But then I see on the serial monitor the connection to the router and it shows the GotIp Address 192.168.1.5 like I have set it in the config. Then it dumps and reset esp. That goes on and on. Do you have a advice what I did wrong?
Thanks
Peter

raising this mainly as a discussion point , and collect information

i recently rebuilt my laptop, and fully updated all the libraries
esp8266 2.4.0 and all the latest Async ESPWebserver libraries

now almost every time the device connects to wifi, gets an IP address, and pings,
but the code is convinced the connection is not working , so sits in the

while (!WiFi.isConnected()) {
    delay(1000);
    DBG_OUTPUT_PORT.print(".");
}

loops at line 580 in FSWebServerLib.cpp

i have compiled the sample asyncwebserver sample which runs with out issue
so i think that is a subtle change i the wifi event handling

more to follow

To the config.html form in the UserConfig example I added to config.html a form line:

This is to pick up a Wunderground API key. How to I pick this value up in the sketch? I am confused on how your code works, I guess.

Got below warnings during compilation:

sketch\FSWebServerLib.cpp: In member function 'bool AsyncFSWebServer::loadHTTPAuth()':

As advised by the warning above, I simply change on these lines on FSWebServerLib.cpp file:

    _httpAuth.wwwUsername = json["user"].asString();
    _httpAuth.wwwPassword = json["pass"].asString();

to this

    _httpAuth.wwwUsername = json["user"].as<char*>();
    _httpAuth.wwwPassword = json["pass"].as<char*>();

No more warnings.

I was on:

• Arduino IDE 1.8.1
• FSBrowserNG master
• ArduinoJSON 5.8.3

Maybe not really an issue but I just don't know if there will be side effects to this library by doing the changes above.

Thanks for the great library though!

Hello
I understand AP mode would be to generate his own SSID and password, the default parameters are inside the code. Unfortunately, my ESP runs into infinite loop (UART output sending constantly strange signs) when I bridge the digital input that should put the module into AP mode.

I would understand I can configure my module with my own router parameters once I am in AP mode with the module which is what I will do during the next step.

Could you please help me to understand what maybe wrong ?
To be mentioned that without putting the module in AP mode with the bridge, I get . (dots) on the UART port.
Kind regards Rolfz

Thank you for some wonderful programming!
I am actively playing with this code, trying to learn how it works..
I can't seem to figure out how to turn on DEBUG so I can see all the DBG_OUTPUT_PORT statements..
I have remarked out #define RELEASE, as per the comment..

I have also enabled debug with ALL in the arduino environment during compile time .. I'm getting debug from the ESP framework.. but not from FSBrowserNG..

Any help would be greatly appreciated as this would drastically speed up my learning..

Thanks again!

Hi... I have a working FTP client on the ESP8266 that I can call a FTP server and request a file... Similar to this.. http://www.rudiswiki.de/wiki9/WiFiFTPServer.... It works but I am working on improving the speed for downloads...
With the FSBrowser how can I force to download a file from the ESP8266 side... vs using the /edit browser on a local computer..?

Hi

This project looks very interesting and I would love to get started playing with it.
I struggle a little bit with your simplest example "StartHere"

All files compilte in the PlatformIO just fine, the "data" folder is added to the project and I see that it's uploaded to the ESP when compiling.
I never get to the AP-point mode.
The serial output just keeps "Attemping WiFi***********" forever.

I have tried to put the GPIO-4 pin high/low and re-power the module with the same result.
IS this the GPIO? or a different pin? I use a NodeMCU v1 ESP12e.
#define AP_ENABLE_BUTTON 4 // Button pin to enable AP during startup for configuration. -1 to disable

Hello,

I'm trying to run this awesome library but i get huge error message in Arduino IDE as well in VSCode PlatformIO. I don't know if this is right place for such question but i did not find any other place to post this.

Here is error message from Arduino IDE: https://pastebin.com/byiDe5Ue
It is quite long and i don't completely understand it. My only guess is that it have something to do with libraries.
I downloaded every library mentioned in dependencies section as ZIP file, unpacked, and pasted into Arduino IDE installation folder (arduino-1.8.1/libraries).

And here error for VSCode: https://pastebin.com/nCXXF86e
In VSCode i did it twice, first time from PlatformIO manager and then manually (pasted libraries folders as above but into lib folder of PlatformIO). Both attempts failed.

What i'm doing wrong? Or this is just problem with newer versions of some libraries? If so, maybe someone could provide me with full package of needed libraries that you are using and they are working just fine?

Cheers!

When I try to compile your example, it says that strftime, gmtime, and time are not declared in this scope. I saw where a few weeks ago you recommended manually installing the esp8266 boards, but this made no difference. Do you have any other ideas? Thanks.
UPDATE: Reinstalled and got it working.

Hi there,

First off, great job you've done here. Congrats.

I couldn't get this this project to work. I strongly believe that is because of libraries versions. I've had lots of problems with this sort of things in past projects of mine. Would it be possible for you to make available the libraries that you used in this project? I know that all the libs are available on GitHub, but to get all of them in the same version you build this project is gonna be a pain.

If you could do so, I'd really much appreciate it.

Thanks.

It appears that Safari doesn't decompress the gz even though the response headers say the content is gzip encoded. Works fine on firefox and chrome.

Here's what Safari thinks the contents of graph.js are:

Full view of the web developer panel, right columns shows headers:

Do we really need blocking begin function? I would like my system work even if no wifi available.

edit - I revised this post substantially. I initially thought this was a Safari problem..

I have encountered several situations where the browser stops responding. LOOP() continues to run fine but the browser is not reachable..

I just about have my Wunderground sketch running properly. It plots actual temp from a sensor along with forecasts. Here's a version that does not use FSBrowser: http://orangecaweather.duckdns.org:8021

In the FSB version I am exposed so I am not giving the link to it!

Right now I am running my sketch after recompiling with ESP8266 RC2 to see if that maters. It looks to my uneducated eyes like there have been a lot of changes that could affect web service. edit - no change :(

If I still have Webserver problems with RC2 my next attempt to fix the problem will be to have the device ping its own IP within LOOP() and restart if it fails.

if ((millis() - currentLoop) > pingTest) {
currentLoop = millis();
if (Ping.ping(WiFi.localIP()), 1) {
//if (Ping.ping(remote_host)) {
Serial.print("ping Success!! Ping Time (mS) = "); Serial.println(Ping.averageTime());
} else {
Serial.println("ping Error :(");
ESP.restart();

}

}

Thoughts?

Bill

Is there a simple way to retrieve the Time Zone and DST flag into my sketch? I could use a user data field but then the user would be entering the same information twice,

Hi there, I've noticed that in readme You wrote that HTTPS isn't supported.
In similar project (Espurna) I found some interesting methods https://github.com/xoseperez/espurna/blob/master/code/espurna/web.ino#L330

#if ASYNC_TCP_SSL_ENABLED & WEB_SSL_ENABLED
    _server->onSslFileRequest(_onCertificate, NULL);
    _server->beginSecure("server.cer", "server.key", NULL);
#else
    _server->begin();
#endif

It look like ESPAsyncWebServer supports SSL.
Maybe this can be added to Your project?

Did You solve 2 Factor Authentication? It would be awesome to have this supported via Google Authenticator App.

Hello

i keep fighting with this.
Is it possible to include an example of a dynamic webpage with the coding to put the data on that page.
I want to enter 2 values (calibration) and to show the temperature of 2 sensors in 1 page.
It should be simple but i am not getting there.

Any help would be aprreciated;

hi,
I was trying to compile the sketch and received this error

\libraries\FSBrowserNG-master/FSWebServerLib.h:84:5: error: 'WiFiEventHandler' does not name a type

 WiFiEventHandler onStationModeConnectedHandler, onStationModeDisconnectedHandler;

How can I resolve this issue?

Thanks.

I'm able to switch to AP by putting pin 4 to ground. In AP mode, I can see the webpages and set WIFI config. However, when I try to boot in STA mode, I can't get it to work at all. The ESP (nodemcu) gets an IP from my router but I can't connect to it or ping it. When I debug to serial, it looks like it gets the IP but then goes into an endless ...................

I also get a WDT reboot after hitting save for the wifi config in AP mode but it does save the configuration.

serial:

Hello!
I do not know if it's proper place to ask, but I can't find answer myself.

When I do analogWrite() on pin 4 or 5 I'm getting disconnected from wifi.
in debug mode on serial monitor I'm getting "bcn_timout,ap_probe_send_start" and ESP can not reconnect.

analogWrite() on pin 2 and 3 is fine.

I'm using nodemcu 1.0 and motor schild.

I don't know how to present my changes:
https://github.com/kaminet/FSBrowserNG_5618/tree/arm

I'm trying to do some time sensitive calculations. My calculations are to calibrate an RTC using NTP.
I'm finding the NTP events are only firing while I have the graphs page open. Once I change pages, it disables the events. How to I keep the NTP events firing?

Here is a snippet of code taken from my modified AsyncFSWebserver::begin

if (_config.updateNTPTimeEvery > 0) { // Enable NTP sync
NTP.begin(_config.ntpServerName, _config.timezone / 10, _config.daylight);
NTP.setInterval(15, _config.updateNTPTimeEvery * 60);
NTP.onNTPSyncEvent ([&](NTPSyncEvent_t event) {
ntpEvent = event;
syncEventTriggered = true;
});
}

This works as long as I'm looking at the web page. (ie /events)

Once I leave that page (or close it) the events stop completely, including the NTP event..

For users in the USA does the Daylight Savings Time button do anything? I am in PST and I have the DST button clicked. The offset from UTC is set to -8 (correct). I would have expected the button to increase it to -7.

I can see where it uses MD5 hash to check authentication for HTTP Auth, Wifi AP mode, and OTA..

My question is, once a password has been entered correctly, how do I clear the credentials?
ie: Logout support?

Are there any plans for an ESP32 version?

Using the Wemos D1 board and the new ESP8266 update from v2.3.0 to v2.4.0 the example above will no longer compile. See below.

Hi,
This looks VERY interesting, BUT I find it odd that you don't have implemented a feature that sets the wifi in AP mode if it fails to connect to the stored SSID.
Wouldn't it be 'easy' and very useful to add this functionality?

Thanks,
Mikkel

When booting into AP mode and no config.json is found, and a user typo's the WiFi credentials, how would a user recover? Thinking of a case where the 8266 was configured and sent to the end-user with the expectation of bootstrapping upon first power-up.

Currently, from testing, the unit writes config.json with incorrect data and proceeds into an endless STA_DISCONNECTED state (at least for 743seconds so far). Does this ever time out and revert back to AP mode? How long does it take?

Second, same scenario when no config.json is found, if a user changes the unit name in general.html a reset is performed. The issue is config.json is written out and contains garbage WiFi connection data, so the unit has a name but never comes online to WiFi. What is the design to recover from this case?

Hi,

Thanks for this magnificent development. I am using this as a starting point for all of my projects relating to esp8266. However, I would like to enhance the graphs.js since I am not able to find a minimalistic graphing javascript library with such a small size relevant for these project. Can you point me where can you get the source for this graphs.js code?

When I comment the RELEASE define to enable debug output ,I find an error
no matching function for call to 'HardwareSerial::printf(const String&)'
how can I make this work ? thx.

Hi Germán,
FSBrowserNG is working for me on a nodemcu v1.0 using the libraries you have specified and the most recent arduino IDE. However when I added some code in the loop it failed. The error seems related to using analogRead(A0) in my code, as it vanishes if I don't use it and generate random data. I can recreate the problem simply with just this code at the start of the main loop:
int n = analogRead(A0);

I found that if I slow down the analogRead to once every 2ms, the problem goes away. However I would
like to sample faster than 500 Hz.

Thanks

Regards, Bill

Hello Germán.

First of all - great library. Thank you for it.

I am a newbie to both C++ and Arduino so it gave me quite some time to understand how it works. Now I think I have a rough idea. I wanted to add my own sensors to the code. As I understood the JSON on URL /all returns the value of the analog input + all GPIOs. I wanted to add something slightly more complex like digital thermometer.

I tried to add following code into the setup():

ESPHTTPServer.on("/temperature", HTTP_GET, [ESPHTTPServer](AsyncWebServerRequest *request) { sensors.requestTemperatures(); String json = "{\"temp\":"+String(sensors.getTempCByIndex(0))+"}"; request->send(200, "text/json", json); json = String(); });

Unfortunately on compile I get following error:

FSBrowserNG:35: error: 'AsyncWebServer' is not an accessible base of 'AsyncFSWebServer'

After some googling I have found a solution by modifing FSWebServerLib.h line

class AsyncFSWebServer : AsyncWebServer {

to

class AsyncFSWebServer : public AsyncWebServer {

That modification helped, the project compiles successfully and gives expected results.

My question is whether I can achieve the same without modifying the library.

Regards

Jiri

do you have an idea what to change

SEK. Thomsen

Hello!

First thanks for that wonderful lib. It's exactly what I needed. :-)

But I stumbled upon a few crashes, which were related to sending Page_WaitAndReload and Page_Restart to the browser. As both are stored in PROGMEM replacing request->send with request->send_P solved the first crashes and made saving the config possible.

The second kind of crash was due to the use of delay() in AsyncFSWebServer::send_network_configuration_html() and AsyncFSWebServer::restart_esp().

I'm new to ESP8266 programming but if I understand correctly, delay() shouldn't be used within a handler. At least removing those two delay() calls fixed it for me.

I just recompiled working code under the new board manager. It compiles fine but I can not bring up the web config web page to get started. I am using a WEMOS D1 Mini Pro

I have the following settings:

Arduino IDE: 1.8.5
esp8266 v2.4.0
Board: NodeMCU 1.0 (ESP-12E Module)
Debug Port: Serial
Debug Level: CORE+WIFI+HTTP_UPDATE+UPDATER+OTA

void setup() {
    Serial.begin(115200);  // added this line.
    SPIFFS.begin(); 
    ESPHTTPServer.begin(&SPIFFS);
}

Changed FSWebServerLib.h as follows:

// #define RELEASE  // Comment to enable debug output
#define DBG_OUTPUT_PORT Serial

#ifndef RELEASE
#define DEBUGLOG(...) DBG_OUTPUT_PORT.printf(__VA_ARGS__)
#else
#define DEBUGLOG(...)
#endif

I am compiling StartHere.ino example and getting the following error:

In file included from C:\Users\Umar\Documents\Arduino\libraries\FSBrowserNG-master\src\FSWebServerLib.cpp:8:0:

#define DEBUGLOG(...) DBG_OUTPUT_PORT.printf(__VA_ARGS__)
^

I have also tried with following settings:

Debug Port: Disabled
Debug Level: None
Not initializing Serial.begin() in the setup().

I still get the same error. Please help!!

Hi, thanks in advance for this project.
I have some questions.
First one: When I comment RELEASE line, and compile pop up error with printf not being a member of StreamString.h I dont know how to fix it.
Second one: what files or folders should be loaded to ESP8266 FS?
Third one : Once it boots up in AP mode. Which is the default IP address assigned to connect and configure ?

Thanks again.

Before I start playing Sorcerer's Apprentice, I think I will ask :)

Here's what I get on the bottom of the info page. All else is fine. I am at a loss to figure what could be wrong. In my sketch NTP time works just fine with function calls to NTP.gettime() . As you can see Uptime is okay and so is Last Sync.

NTP Date: 01/01/1970
NTP Time: 00:25:43
Last sync: 14:18:10 22/11/2017
Uptime: 0 days 00:25:43
Last boot: 00:00:00 01/01/1970

Any ideas on where to start troubleshooting this?

Bill

I don't quite understand what this issue is.. I get this error:

C:\Users\SB 55\Documents\Arduino\libraries\ESPAsyncWebServer-master\src\WebHandlers.cpp:78:25: error: 'time' was not declared in this scope

if(time(&last_modified) == 0) //time is not yet set

any ideas?

Hello gmag11,

First off, this is a fantastic project, it works beautifully when it comes to serving HTML files and it is very fast. Secondly, I'm relatively new to this and I don't know where else to ask this question so I'll put it here:

Can you maybe add some functionality to the main page along with some explanations? It's nice to read the status of the analog input and the GPIO pins, but do you think that you can have a write example in there somewhere as well?

This is a really complex project for a beginner like me, and it would really help a lot if you could add some more examples and support. Right now I can't even find the code you are using to read the status of the GPIO pins, and if you could add a simple button to turn on and off one of the pins, along with an explanation of how you did so, that would help a lot of people I'm sure!

Thanks! (Feel free to move this to wherever it needs to go)

I can compile starthere and use it but there is no output of the IP address for the connection to the site onboard. I have to use the network watcher to see what ip address is added and use then that one.
Is there a way to see the address on serial output or somewere else?
Many thanks

i get this error:

This issue is just to inform the steps i had to go through to make FSBrowserNG compile for ESP8266.

problem: ESP8266: unknown type name 'time_t' time_t tv_sec
see Sloeber/arduino-eclipse-plugin#851

problem; ESPAsyncTCP: 2.3.0 ESPAsyncTCP.cpp:839:30: error: invalid conversion from 'long int (*)
see me-no-dev/ESPAsyncTCP#61

I was having a less then 1 in 4 WiFi connection success , from either cold boot, warm reset or upload

in my fork (not yet commited) i have changed to (which seem to fix the issue)

void AsyncFSWebServer::configureWifi() {
WiFi.disconnect();
WiFi.mode(WIFI_STA);
//currentWifiStatus = WIFI_STA_DISCONNECTED;
