iotwebconf's Issues

PW's displayed in clear text in Serial monitor

First of all.....thanks for your work on this library! While I have made a lot of changes and modifications for my use, you have saved me a lot of time and effort.

I started at version 2.1.0 and am currently using 2.2.1. My question is in regards to the WIFI passwords being displayed in clear text when Serial logging. In IotWebConf::configSave(), unless you #define IOTWEBCONF_DEBUG_PWD_TO_SERIAL, the WIFI passwords are shown as "<hidden>". However, when you change the WIFI password(s) and save the configuration parameters at "/config" and IotWebConf::readParamValue() runs, the WIFI passwords are shown in clear text.

Is there a way to hide them in the second case?

Thx

Internal parameters (setter)

Is it possible to have a sample or setters for modify the following internal parameters?
Why? After the first boot and initial configuration, I have a touchscreen display and I want to modify the value directly from the display.
Perhaps i need to reset entirely the previous configuration.

Also, how to access others parameters like MQTT id and pasword? What am I supposed to do? Reread the EEPROM from my stuff?

/**
     * Get internal parameters, for manual handling.
     * Normally you don't need to access these parameters directly.
     * Note, that changing valueBuffer of these parameters should be followed by configSave()!
     */
    IotWebConfParameter* getThingNameParameter() { return &this->_thingNameParameter; };
    IotWebConfParameter* getApPasswordParameter() { return &this->_apPasswordParameter; };
    IotWebConfParameter* getWifiSsidParameter() { return &this->_wifiSsidParameter; };
    IotWebConfParameter* getWifiPasswordParameter() { return &this->_wifiPasswordParameter; };
    IotWebConfParameter* getApTimeoutParameter() { return &this->_apTimeoutParameter; };

Dynamic parameters?

I wonder if it is possible to create dynamically parameters without any errors. Now when I declare a parameter inside the setup function, the parameter is available in the config page, but the parameter div is given the class "de" because the current->errorMessage is not NULL. The error below the input field is mostly "~" but sometimes another random character.

I've edited the example sketch IotWebConf03CustomParameters as a test:

I can edit and save the parameter without any problem. After saving the "de" class is gone. After a reset of the ESP the error is back again.

mDNS and connecting to hostname.local , I cant seem to get it to work

Am I the only one having this issue?

If so can someone walk me through how to set this up.
Its automatically setup as my "thingname" right?
Or is there another step I need to take to init it.

Sorry if this is a stupid question! I'm far from an expert.
Everything else is working great though!

how to get IP Address

I like and use this library.
There is one feature I miss or at least I don't know how it works:
Before I used the WiFi class which supports the WiFi.isavailable and IPAddress function.
I need to print out the IP Address once it's either connected or it opens an access point (...).
I have seen that I can register a callback once it's connected but how to get the IPAddress?
Which function do I have to use/call to get the IPAddress?

Does not play nice with FreeRTOS queues and tasks with Arduino SDK

Hi! I am trying to run IotWebConf with Arduino IDE using queues and tasks.
But I get errors - serial monitor closes connection.

I have few tasks:

  • Receives messages from queue and process them (outputs to serial)
  • Sends demo data to CAN bus
  • Loops iotwebconf every 10 msecs.

Any ideas how to make it all play nice together?

Disable Serial Debug

Hi thanks so much for the amazing library.

Is there a way to completely disable the serial debug without having to remove it from the library?

Thanks in advance

Preprocessor statement in IotWebConf.h is incorrect

#ifdef ESP8266
# include <ESP8266WiFi.h>
# include <ESP8266WebServer.h>
# include <ESP8266HTTPUpdateServer.h>
#else  defined(ESP32)
# include <WiFi.h>
# include <WebServer.h>
#endif

#else defined(ESP32) is not a valid preprecessor statement.

Should probably be

#if defined(ESP8266)
# include <ESP8266WiFi.h>
# include <ESP8266WebServer.h>
# include <ESP8266HTTPUpdateServer.h>
#elif  defined(ESP32)
# include <WiFi.h>
# include <WebServer.h>
#endif

store numbers as numbers

Very interesting project, Thanks for providing the code!

except for the missing espasyncwebserver (issue #24), i'm wondering about one more thing:

e.g. in example IotWebConf03CustomParameters.ino, there's a Int, limited with min/max from 1-100, and it's stored in RAM and Eeprom as a 32byte string.

in that case it could be done using one byte - type uint8.

is there a reason you went the char[32] route?

except for the waste of resources, it would be easier is the user-code could access the value of the parameter in correct type (so no need to add another uint8_t and convert from char[] to uint8_t...

it would be very great to have support for unsigned/signed int 8/16/32 as well as float.

what do you think?

Compile errors with new version of Arduino IDE (1.8.9)

Hello,
today I updated my Arduino IDE from 1.8.3 to 1.8.9.
On 1.8.3 my source code, which uses IotWebConf, was compiling and working well.
After that upgrade, I get a lot of errors:

Device Crashes with interrupt during change of connection state

Hi All!
I'm using a high-resolution encoder that uses interrupts to track the length of material traveled.
I'm running into a significant issue that crashes the device when the encoder is tracking and iotWebconf switches connection state at the same time.
This happens with both the ESP8266 and the ESP32.
Does anyone have any idea why this would happen?
I can't for the life of me figure it out, and it's super important for my project that this doesn't happen.
Let me know if there is any info I could give to help!

Thanks in advance!

Do not print passwords by default

Please, disable passwords prints by default. It can be enabled via additional #define if needed
This prevents e.g. online demos and conference calls... Even showing to the friends over the table doesn't looks safe. Needless to say somebody smart enough can use a portable serial analyzer to still this from already working iot.

I know there is a #define for disabling all prints, but I still would like to have the rest of them.
You did a great security considerations forcing people to set the passwords to device, but this prints reduces security a lot.

Switch off and on the wifi

Hello,

probably it's a weird thing to do, but in my project I don't want to use the wifi all time long, just for some time to set the time up and change the settings.

Is there any way to switch off the wifi (without connecting to the local network or creating an ap) and then switch it on again?

Thanks!

use of mDNS

It is hard to find the IP of the device in real world applications where serial monitor is unavailable. May be local domain name option can help access to the device more easily. Something like thingConfig.local

Drop-down menu for custom parameters?

Hello all!

This is either a feature request or just a request for help.
I am by no means an expert on this stuff, so I'm sorry in advance if this is a stupid question hahaha.

So, for one of the custom string parameters id like to create a drop-down menu with only a few specific options, rather than just a text field. Or really any menu that allows people to choose from only a few options rather than having to type it in.

Is there a simple way to do this? Or is this a feature you would be willing to add?

Any help would be greatly appreciated!

Errors after upgrading ESP8266 board package version from 2.4.2 to 2.5

Hi, I am having issues after upgrading ESP8266 board package version from 2.4.2 to 2.5
I am using IotWebConf 1.2.0
Board resets after changing from state 2 to 2 and trying to connect to WiFi.
Do you have some information regarding this?
I downgraded to 2.4.2 to workaround the issue but iยดd like tu updgrade.

By the other hand I need to connect to 2 different MQTT brokers using TLS. So I am doing the following but I am failing to make it work. Can somebody give me any hint?

At the beginning:

WiFiClientSecure net;
MQTTClient client;
WiFiClientSecure net2;
MQTTClient client2;

in setup()

  client.begin("broker1.com", 8883, net);
  client.onMessage(messageReceived);
  client2.begin("broker2.com", 8883, net2);
  client2.onMessage(messageReceived);

in loop()

  client.loop();
  client2.loop();

Thanks in advance.

Default Values not working

IoTWebConf Version 2.3.0
Using an ESP8266

IotWebConf iotWebConf(thingName, &dnsServer, &server, wifiInitialApPassword, CONFIG_VERSION);
IotWebConfSeparator separator2 = IotWebConfSeparator("Nutrients");
IotWebConfParameter mlGallon = IotWebConfParameter("ML Per Gallon", "mlGallonParam", mlGallonValue, NUMBER_LEN, "number", NULL, "4.9", "step='0.1'");
IotWebConfParameter separator3 = IotWebConfSeparator("Advancied Config (Leave defaults if unsure)");
IotWebConfParameter ticksGal = IotWebConfParameter("Ticks Per Gallon", "ticksGalParam", ticksGalValue, NUMBER_LEN, "number", NULL, "3200", "min='1' max='100' step='1'");
IotWebConfParameter msMl = IotWebConfParameter("ML Per Second", "msMLParam", msMLValue, NUMBER_LEN, "number", NULL, "320.0", "step='0.1'");

The above configuration will show all custom parameters, but the set defaults are not in the input fields, nor does IoTWebConf set the appropriate defaults when the fields are left blank.

I know this issue was supposed to be fixed in 2.1.0, but seems to be reintroduced in 2.3.0.

Disconnection Debugging

Could you give an example of handling connection failures? I don't want the library falling back to AP if there's a connection problem, I want to keep trying without blocking and log this.

I see setWifiConnectionFailedHandler, do you have an example?

Change of standard labels and parameters

Hi, @prampec .
How can I change the default labels ("Thing name", "AP password", "WiFi SSID", "WiFi password", "Startup delay (seconds)") for these parameters?
I will be grateful for the answer or for the implementation of this.

this->_thingNameParameter = IotWebConfParameter("Thing name", "iwcThingName", this->_thingName, IOTWEBCONF_WORD_LEN);

this->_apPasswordParameter = IotWebConfParameter("AP password", "iwcApPassword", this->_apPassword, IOTWEBCONF_WORD_LEN, "password");

this->_wifiSsidParameter = IotWebConfParameter("WiFi SSID", "iwcWifiSsid", this->_wifiSsid, IOTWEBCONF_WORD_LEN);

this->_wifiPasswordParameter = IotWebConfParameter("WiFi password", "iwcWifiPassword", this->_wifiPassword, IOTWEBCONF_WORD_LEN, "password");

this->_apTimeoutParameter = IotWebConfParameter("Startup delay (seconds)", "iwcApTimeout", this->_apTimeoutStr, IOTWEBCONF_WORD_LEN, "number", NULL, NULL, "min='1' max='600'", false);

feature request

hello, I would like to use your iot, to control an LED via mqtt and adafruit.
Adafruit requires 4 parameters to add to the Ap configuration:
server name, port. user and aiokey.
in your examples I did not find the possibility to change the mqtt port.
what is the correct method to add these parameters?
Thank you for your time

Do not reset system config when config version changed.

Suggestion:
Let's separate system config (ap password, siid, etc) and custom config versioning.
I assume a version for system config part can be hardcoded and will be only affected when user upgrades to the next release, where those configs layout been changed. While the rest of config is versioned by developer. In this case, when developer changes his custom config layout & bumps a version (or user uploads new firmware), he will not be forced to start over again and configure IoT via AP mode. Device will continue to connect (because those builtin setting will be preserved). User will be able to login on iot inside wifi and update new custom config much easier and faster.
Digging in more details, I suppose system-part data should go first to avoid any offsets (I suppose it already goes first?). This means, when system part is changed - both parts must be reset (PS: if only we don't add some padding for future upgrades)

User-configurable library settings

Thanks for all the owrk on this library - really useful.

I'm already using EEPROM in setup()
EEPROM.begin(336);

Your library redefines it
EEPROM.begin(IOTWEBCONF_CONFIG_START + IOTWEBCONF_CONFIG_VESION_LENGTH + size);

With this, memory is messed up for your code and mine.

Having limited knowledge of C++, I cannot figure out how to specify my memory requirements without changing your library code, which seems to me to defeat the use of a library.

At the moment I have changed the following lines:

IotWebConf.cpp line 200 - //EEPROM.begin(IOTWEBCONF_CONFIG_START + IOTWEBCONF_CONFIG_VESION_LENGTH + size);

IotWebConf.h line 28 - #define IOTWEBCONF_CONFIG_START 336

Now I'm looking at other settings that can't be changed except by altering the library code, such as IOTWEBCONF_CONFIG_USE_MDNS, IOTWEBCONF_DEBUG_TO_SERIAL, and IOTWEBCONF_ADMIN_USER_NAME.

Am I missing something? Or can you make these settings and options configurable when initialising the library?

WiFi password length

the input for WiFi password length is limited in the definition file to 33 chars -> for WPA2 the SSID can be max 32 char and the password 63 char

Can you give me a hint?

Can you give me a hint on how I should update a custom parameter from code without using web?

For instance...

char stringParamValue[STRING_LEN];

IotWebConfParameter stringParam = IotWebConfParameter("String param", "stringParam", stringParamValue, STRING_LEN);

void update_param() {

**What should I write here to assign "Hello" to the parameter**

configSaved(); 
}

Thanks in advance

Best regards.

Crash when errorMessage is not initialized

When rendering the page for the first time no error message is present for the thingName parameter. When replacing the {e} parameter in the template it crashes.

Solution: Initialize error message in constructor.

IotWebConfParameter::IotWebConfParameter(
const char *label,
const char *id,
char *valueBuffer,
int length,
const char *type,
const char *placeholder,
const char *defaultValue,
const char *customHtml,
boolean visible)
{
this->label = label;
this->_id = id;
this->valueBuffer = valueBuffer;
this->_length = length;
this->type = type;
this->placeholder = placeholder;
this->customHtml = customHtml;
this->visible = visible;
this->errorMessage = "";
}

Unfortunately could not make a branch/pull request. Could you check this and update the repo so will be fixed on PlatformIO?

Thanks!

"thingName" help please

Hi, I know this is not really a issue about the library, but im new to C++, 2 days surfing the web triying to learn about char arrays, pointers and references, but im done, cannot guess how to assign ESP.getChipId() and ESP.getFlashChipId() to thingName, can you give me a clue please?

This is what a wrote:

const String brandName =  "IH";
const String deviceType = "SWITCH01";
const String deviceVersion = "v0.1";
const String espCID = String(ESP.getChipId());
const String espFID = String(ESP.getFlashChipId());

I've tried a lot of std::string, strcpy, strcat, and many others that I cant remember.
So, how can I make thingName look like something like this (concatenation)?:

const char thingName[] = brandName + "-" + 
    deviceType + 
    deviceVersion + "-" +
    espCID + 
    espFID;

thanks in advance!!

Q: WiFiScan

Can an addition be made that the list of found networks are displayed in AP mode?
Scan results can indicate if a wifi has protection, which could be used to hide the password field.

Configuration options i can think of are:

  1. ScanWiFiNetworks(true|false) = false = display text box, true = execute WiFi.scanNetworks(); and populate selectbox.
  2. MinimumRssiNeeded
  3. ListOpenNetworks(true|false)

AP Error

I try the example IotWebConf06MqttApp as I need it to pre-test.

I comment all stuff from MQTT and when I try to connect to AP I have the following error :

My config is a ESP32.
I precise, with same code, it's ok with a ESP8266.
Something wrong ?

Setting Hostname

Is there a way to set the hostname?
Currently the device appears as: ESP_nnnnnn (when connected)
It would be nice to have an option to set hostName = thingName
or even better to have an extra field on the config page to set the hostname individually.

Wrong config version

I am getting the error
"Config size: 165
Wrong config version."
presumably, since I played with other WifiManagers before this one :)
Using iotWebConf.setConfigPin(CONFIG_PIN); and pulling this pin to ground seems to have no effect.
Is there a way to delete an "old" config?

Error in AP mode

Everything was working fine, but now I have this error, when I load up a new module or if I force an existing one back into Ap mode by connecting to it from my phone.

E (27188) event: mismatch or invalid event, id=63
E (27189) event: default event handler failed!

It seems to be something to do with the ESP32 libraries themselves, but I just cannot get any of my projects that I have build with the IotWebConf to work anymore if the device is in AP mode?

Anyone got a work around?

Cant Write To EEPROM

I don't know why , i can't write to EEPROM when i'm Write after (for example) :

EEPROM.begin(1024); 
iotWebConf.addParameter(&separatorshift1);
iotWebConf.addParameter(&Param_value_1);
iotWebConf.addParameter(&Param_value_2);

EEPROM.write(600, 12);
EEPROM.write(601, 23);
EEPROM.commit();

if i write before that, i can successfully write to the EEPROM,
any idea why this happened ?

ESP8266HTTPUpdateServer class compile error on Wemos D1 mini

I get an error when compiling IotWebConf in Arduino IDE for Wemos D1 mini. It shows up even when I try to compile your "IotWebConf01Minimal" example from the repository.

I have searched the net without any luck, so now I try this way. It would be nice to solve this, because I really would like to use IotWebConfig instead of WifiManager. ;-)

And thanks a lot for the good work with IotWebConf !

How to work only in AP mode

Hello,

This not an issue but more a question:
In my use I just need that my esp32 work in AP mode. But I would like to be able to change the SSID or password of the AP, and other specific things. (this AP will broadcast data by udp)

So how to make IotWebConf only working in AP mode (and not switch to station mode and try to connect to a network.) ?

Thanks

Emmanuel.

Some way of hiding default config parameters

Apologies if I'm missing something but I'd like to be able to hide some of the default config parameters, for example the startup delay and I can't see a way to do that right now.

add a firmware update progress bar

@prampec I wrote some code to add a progress bar when using an OLED display on an esp32. How do I go about adding it so it displays when a user clicks "upload"?
I'm guessing somewhere between:
if(upload.status == UPLOAD_FILE_START){
if(Update.end(true)){
Can this be done by calling it from the main sketch?

Default value in config form

Hi,
I have just a question,
It seems that default value is not working on the configuration form when empty.
Can you help me by telling me if I am doing something wrong?
Placeholder text is showing ok but if field is not completed default value is not saved.

char mqttServerValue[STRING_LEN];

IotWebConfParameter mqttServerParam = IotWebConfParameter("MQTT server", "mqttServer", mqttServerValue, STRING_LEN, "text", "mymqttserver.com", "mymqttserver.com", NULL, true);

void setup() { iotWebConf.addParameter(&mqttServerParam); }

Am I doing something wrong or my expectations are wrong and the behavior is the expected?
What I need to achieve is that if field is not filled by user, then the default value is saved.

Tanks in advance for your support.

Reset a IotWebConfParameter to default?

Is there a way to reset a parameter after it has been configured through the web interface?

I tried the web interface to a separate database containing nodes with a custom struct. When I delete the nodes in the database, I would like to go back to the web side and reset the values to their defaults. Otherwise, when a new parameter is created, it inherits the settings saved for the previous parameter.

It would be especially nice if it was a public function so it could be called from other source files.

Password parameter visibility

Is it possible to add the functionality, like in Android (as picture below) and some others OS, to have an icon to make visible the password?
