tonyp7 / esp32-wifi-manager Goto Github PK

Good day. Firstly let me say thank you for the awesome code which you have developed.
I would like to use this code in one of my projects but I have the need to enter more data strings like IP address and device name and store them in NVS. Could you please let me know whether this is at all possible and how I could implement it?
Thank you.

Hello,

With 3.1.2 esp-idf version, I'm struggling to connect iPhones to Wifi manager while it is working fine with Androids' phones.

Does anyone face the same issue ? Any tricks ?

sorry can you shown me where the fully code , my English was not so well .......

I just build the source and do run. When I'm connecting to ESP32 wifi(STA) in mobile module getting restarted

Hi tony,

Does this wifi manage uses dynamic ram allocaton for wifi or static.
Where in the code I can specify not to use dynamic ram.

in my menuconfig I specify only static ram. I don't want to use dynamic ram for wifi.

but my debug logs on startup shows some dynamic ram allocations.

I (1105) wifi: Init dynamic tx buffer num: 32
I (1108) wifi: Init data frame dynamic rx buffer num: 64
I (1113) wifi: Init management frame dynamic rx buffer num: 64
I (1119) wifi: Init static tx buffer num: 12
I (1123) wifi: Init static rx buffer size: 1600
I (1127) wifi: Init static rx buffer num: 12
I (1131) wifi: Init dynamic rx buffer num: 0

Kindly do reply.

Thanks,
Naeem

I am able to connect to ESP32 AP. it open up a HTML page but there is no Wi-Fi list in that page.
I am trying this on android phone as well as on windows phone. Not working on android but the same is working on windows phone.
Can anyone help me out. Thanks in advance.

If a DHCP address isn't acquired within a defined time period, default to first start config.

// configure the softAP and start it */
wifi_config_t ap_config;
ap_config.ap.ssid_len = 0;
ap_config.ap.channel = __wifi_settings.ap_channel;
ap_config.ap.authmode = (wifi_auth_mode_t)__wifi_settings.ap_authmode;
ap_config.ap.ssid_hidden = __wifi_settings.ap_ssid_hidden;
ap_config.ap.max_connection = AP_MAX_CONNECTIONS;
ap_config.ap.beacon_interval = AP_BEACON_INTERVAL;
memcpy(ap_config.ap.ssid, __wifi_settings.ap_ssid, sizeof(__wifi_settings.ap_ssid));

Hi,

Thanks again for a nice program.

I've run into an issue combining the wifi-manager with MQTT. If I use a the MQTT app (task) separately (stand alone) it is able to publish messages okay to a remote host. However, if I use MQTT app (task) with wifi-manager, the MQTT app is not able to connect to the remote host to publish messages. I've gone through the wifi-manager code, and tested different options. So far I've not found a solution to why the MQTT app will not work along aside the wifi-manager.

I have been able to use the wifi-manager to select an access point and store the access point credentials to NVM. Then on a reboot, I check to see if there are access points credential in the NVM, If there are, I used those credentials to attached to the access point and start the MQTT app. I don't start the wifi-manager up in this case. This configuration works okay.

Have you run see this issue? Do you have any recommendations on combining wifi-manager with MQTT?

Thanks,
Robert

Hello, awesome work on this wifi manager btw!

I am using the wifi manager and thought it would be great to have the ability to create a new AP ssid and password over the webpage. I was trying this, but I am having major troubles modifying the wifi_manager.c file to enable saving the new credentials to the flash and retrieving them upon restarting the ESP - so I thought I would ask if you have any plans for this in the future?

all the best

Whenever I change the value in the header file Wifi_manager for the AP or AP/STA config, the program breaks and throws this error:

****ESP_ERROR_CHECK failed: esp_err_t 0xb (ERROR) at 0x400d397b

Even trying to change the value back and reflashing the board doesnt fix it. Any ideas?

Hi,
I'm new to ESP32 development. I use the Arduino IDE, and would like to know how to use the Wifi manager with it.

thanks!

Hi,

I need to keep track of now many WiFi clients are connected to my Access point. I run my application with both AP and STA modes.

I need to keep count of how many WiFi clients are connected to me via AP or STA and when it disconnect we get event. then we can decrement count.

Hi,

I am new to ESP32, so my apologies if I am missing out something obvious.

I downloaded the esp32-wifi-manager and tried to compile the project, using vscode, ESP-IDF 3.2 and mingw32 under windows. It compiled fine, starts and using make monitor I see the attached log.

No errors present, but I do not see any Access Point when scanning for it. Hence I cannot connect and configure the STA.

esp_wifi_start() in wifi_manager.c, line 577 returns ESP_OK.

I am puzzled, what the problem might be.

I m using the Heltec esp32 wifi board.

Any help appreciated.

Kind regards

Instead of going to http://192.168.1.1, is it possible instead to go to "http://myesp.config". Is that possible?

Hi,

Can you test your wifi manager start and stop in freeRTOS dual core mode.

Thanks,
Naeem

Skimming through the code, it seems that the expected behavior is to connect to the network via web server, being the device in sta+ap mode and change to only sta mode. But this doesn't happen

Hi. I have downloaded your code and try to to run it. This is what I get:

Any idea why it reboots at /wifi_manager.c" line 580?

Hello,

Thank you for your useful contribution.

In my application I do not use the callback feature, instead I read bits from the wifi_manager_event_group.

There is a race condition where if I read from the group before wifi_manager's task is started I will crash trying to read a group that hasn't been created yet.

Why not just create it in the very first method, the start method?

`
void wifi_manager_start(){

/* disable the default wifi logging */
esp_log_level_set("wifi", ESP_LOG_NONE);

//move to here
wifi_manager_event_group = xEventGroupCreate();

`

Also, recommend that you initialize it to zero at the top of the file :)

Thanks Again,
QC

I need to start my application AP mode and then after scan and join another AP. I need to disconnect and connect to STA only.
Is it possible?

just a very tiny change needed to move xEventGroupSetBits() call outside of #if/#endif.

patch.txt

When http_server.c copies the javascript / jquery / json / html files, it calculates the length incorrectly which ends up copying one byte past the end of the text. This breaks the javascript.

Great applications. Thanks.

I was wondering if you happen to have a human readable verions of jquery.js?

Thanks,

Rebooting...

I believe it has something to do with how the wifi_settings_t struct gets created initially. Not sure (I'm terrible with C).

Does nothing if you want to join an open wifi network.

Hi,

https://esp32.com/viewtopic.php?f=13&t=8319&p=35283#p35283

Can some one tries with latest code. putting wrong password.

Thanks,
Naeem

I have included the wifi manager in my code and what my code does is it hosts a webpage but when I try to open the webpage in my browser it shows your webpage instead of mine even though I am on a home network where esp should be connected as station hosting the webpage.

Also, how can I retrieve the ssid and password from your code so I can manually start my station code thus solving the above-mentioned problem

The following use case:

1. Application is fresh loaded in ESP32
2. Location A
   2.1 Start: connection from client to 192.168.1.1
   we see the list of networks, we can connect.
   The configured connection: "NetworkA"
3. Location B, network "NetworkA" is not there.
   3.1. connection from clien to 192.168.1.1.
   No list of available connections is shown.
   A Try to manual connect does not work.
   3.2. From Postman request GET /status.json gives the name of "NetworkA"
4. on host PC from Postman: request DELETE /connection.json
5. 1 status is cleaned
   4.2. 192.168.1.1. gives the list of available networks

Resume:
it is not possible from HTML interface alone to reconfigure the settings.
First the request DELETE /connect.json restarts the application.
THe Button "RESET connections: with action request DELETE could fix the issue

I'm newbie in HTML and my own HTML experience are to small to fix it clean

Hello, thank you for great wifi manager!

I've got an issue, when I'm trying to append wifi manager to program with ULP I catch error with undefined reference

/home/tetenkov/esp/esp32-wifi-manager/wifi_manager/build/main/libmain.a(baremetal.o):(.literal.init_ulp_program+0x0): undefined reference to _binary_ulp_app_bin_end' /home/tetenkov/esp/esp32-wifi-manager/wifi_manager/build/main/libmain.a(baremetal.o):(.literal.init_ulp_program+0x4): undefined reference to _binary_ulp_app_bin_start'

I really change nothing in ULP programming logic, I follow Programming Guide but when I add wifi manager files it fails.

https://esp32.com/viewtopic.php?f=13&t=7761

kindly check this and reply.

Hi,

I've integrated wifi manager into a battery operated mailbox detection solution. Here I've used the ESP-Wrover module because it can operate on lower voltages. It is powered by 2 x AA.

I notice from time to time that the wifi credentials are lost and needed to be re-configured with the wifi manager ui.

Any idea what can cause this behavior?

Thanks,

First of all, congrats to excellent coding on ESP-IDF, this is awesome ;-).

I have a few suggestions:

• Made this as component for easy deployment
• The password with confirmation (2nd entry for it)
• When finished, put one button to close the captive portal

Best regards

Hi,

How this application specify 192.168.1.1 as AP IPv4 address.

I cannot find source code line where It specify it.

Just to confirm It is running in both AP and STA mode. after connect to any AP.

Is web files are part of .bin image?

Hi there,

first of all "Kudos!" for such a nice project! Loving it!

I wonder if it would be possible to include support for the ESP32 WiFi Long Range Mode (https://blog.hackster.io/long-range-wifi-for-the-esp32-9429ab89f450) ?
This way this project could be used as a "WiFi LR <-to-> WiFi" Bridge and LR devices (such as ESP32 based IoT sensors and devices) could be connected to a standard Home WiFi over massive distances. That would be really nice! Distances of 1-10km can be achieved with this mode.

The WiFi-Manager would run a SoftAP with LR Mode enabled and communicate to the other WiFi networks nearby in standard WiFi Mode.

Best regards and keep up the excellent work!
Cheers!
Thomas

Good day,
I changed the default AP_SSID in the wif_manager.h file but after I flash the file the ssid of the ap does not change?
Can you please advise on what I may be doing wrong and how to achieve this?
Thank you

Hello friends,
I'm starting to learn how to use IDF.
I am trying to write the default_demo example but it is giving the error:
"Executing" ninja all "...
[1/5] Performing build step for 'bootloader'
ninja: no work to do.
[2/3] Linking CXX executable wifi_manager.elf
FAILED: wifi_manager.elf "

I believe I am installing the wifi_manager library the wrong way.
I'm putting the "default_demo" folder and the "scr" folder in the esp_idf root, is that it?

thank you for now

Thanks for a great application!
I have a few more needs myself and I am trying to find my way through your code but have not yet managed to do what I want:

1. From the main web page bring up a new page "Settings" (for instance by clicking the "WiFi header")

2. In the Settings page be able to:
   a. Set (and store) a new name for the AP
   b. Set (and store) a new WiFi channel for the AP
   c. Select (and store) if the AP should be turned off whenever esp32 is successfully connected as a WiFi client (i.e. switch to "STA" mode instead of "APSTA" whenever connected to a WiFi router)
   d. Select (and store) if WiFi Power save mode should be enabled when in client mode

3. In my own application, I think I will need to use websockets instead of regular Json pulls due to latency. If WiFi-manager could be changed to use websockets instead of regular Json pulls, then I guess it would make WiFi-manager:
   a. acting more in "real time" when scanning for WiFi AP's or when signal strengts varies etc
   b. easier to integrate with applications that need to read/control I/O pins in "real time" (like my app)

Any chance that you are already working on similar additions to WiFi-manager (to save me hours of work :-) )?

Hey there,
I'm writing an application on top of wifi-manager that extends the web server such to support my own API. In development I noticed that the esp_wifi_scan_start appears to be stealing 2.5s of CPU time every time it runs (which if often). My next course of action is to disable scanning once the unit enters STA however I was wondering if it was something you've come across and if there are more event driven alternatives?

Alex

else if(uxBits & WIFI_MANAGER_REQUEST_WIFI_SCAN){			             
  int64_t timeBeforeTasks = esp_timer_get_time();
  ESP_ERROR_CHECK(esp_wifi_scan_start(&scan_config, true));
  int64_t timeAfterTasks = esp_timer_get_time();
  printf("time to scan AP list: %lld ms\n", (timeAfterTasks-timeBeforeTasks)/1000);

time to scan AP list: 2500 ms
time to scan AP list: 2497 ms
time to scan AP list: 2497 ms

Are there any example of how to implement this solution and it's require dependencies?

When I try to build, make sets defaults. menuconfig lets me change those defaults, so I can change the name and password, but there is no option to change auth type. So when I leave a blank password, the esp just keeps crashing. Changes in the header dont work since they are overridden by kconfig during the build.

I need a way to set the password blank and the network type to open.

http_server.c line 169

if ((sizeof(host) > 0) && !strstr(host, DEFAULT_AP_IP)) {

should be

if (host && !strstr(host, DEFAULT_AP_IP)) {
or
if (lenH > 0 && !strstr(host, DEFAULT_AP_IP)) {

And if Wifi is running in STA mode, then it can't be accessed via the network.

Great Work, awesome project!
I have a problem though - I can't get wifi_manager_destroy(); to work.

As for a basic test I simply added it to the callback:

void cb_connection_ok(void *pvParameter){
	ESP_LOGI(TAG, "I have a connection!");
	wifi_manager_destroy();
}

I think the problem lays within vTaskDelete() - it seems the function is entered but never left.

void wifi_manager_destroy(){
	ESP_LOGI(TAG, "trying to kill wifi manager");
	     if( task_wifi_manager != NULL ) vTaskDelete(task_wifi_manager);
		else ESP_LOGI(TAG, "This is not the Task you are looking for.");
	ESP_LOGI(TAG, "Success deleting task");
	task_wifi_manager = NULL;

Last Output is:
I (4511) wifi_manager: trying to kill wifi manager
"Success deleting task" is never printed.

I can delete other tasks on my project though (eg heap monitor).

Any Idea why this is happening? It's unclear to me.

Hi,
I managed to flash wifi manager on my esp32. Now I would like to add functionality that will check if some pin is high state. If that is true just make a post request or connect to mqtt.
How would I do it?

Hi. I'm trying to connect to aws_iot, but I get "aws_iot: failed! mbedtls_net_connect returned -0x52" error. This error may be a network connection problem. The point I'm curious about is how the network configuration of the aws configuration is trying to connect and how I can select it.
I'm using aws embedded c sdk.

and

I call aws_set_event_start() in the following code block.

		uxBits = xEventGroupWaitBits(wifi_manager_event_group, WIFI_MANAGER_WIFI_CONNECTED_BIT | WIFI_MANAGER_STA_DISCONNECT_BIT, pdFALSE, pdFALSE, portMAX_DELAY );

			if(uxBits & (WIFI_MANAGER_WIFI_CONNECTED_BIT | WIFI_MANAGER_STA_DISCONNECT_BIT)){

				/* Update the json regardless of connection status.
				 * If connection was succesful an IP will get assigned.
				 * If the connection attempt is failed we mark it as a failed connection attempt
				 * as it is important for the front end app to distinguish failed attempt to
				 * regular disconnects
				 */
				if(wifi_manager_lock_json_buffer( portMAX_DELAY )){

					/* only save the config if the connection was successful! */
					if(uxBits & WIFI_MANAGER_WIFI_CONNECTED_BIT){

						/* generate the connection info with success */
						wifi_manager_generate_ip_info_json( UPDATE_CONNECTION_OK );

						/* save wifi config in NVS */
						wifi_manager_save_sta_config();
						#if WIFI_MANAGER_DEBUG
									printf("aws_start_Bit\n");
						#endif
						aws_set_event_start();
					}
					else{

						/* failed attempt to connect regardles of the reason */
						wifi_manager_generate_ip_info_json( UPDATE_FAILED_ATTEMPT );

						/* otherwise: reset the config */
						memset(wifi_manager_config_sta, 0x00, sizeof(wifi_config_t));
					}
					wifi_manager_unlock_json_buffer();
				}
				else{
					/* Even if someone were to furiously refresh a web resource that needs the json mutex,
					 * it seems impossible that this thread cannot obtain the mutex. Abort here is reasonnable.
					 */
					abort();
				}
			}

While testing my current project with different devices I noticed that there is no page splash on a samsung device.

Some digging turned out, that they behave a bit special. As solution it is suggested to answer with an empty 204 packet (??). I usually don't have to deal with DNS-stuff ^^'

Anyhow - I'm trying to implement some code to catch that problem. But any help would be highly appreciated.
I'll update this Issue as I make any progress.

Hi,

Thanks for sharing this great work!
I've made it run as it is but now I'd like to use it as a library. Is it possible to use it in PlatformIO? I've managed to add it to the project (with pio lib install <url>, and lib_deps = esp32-wifi-manager), but couldn't make it work there. I copied the file main.c to my src, and updated the includes inside as follows:

#include "wifi_manager/main/http_server.h"
#include "wifi_manager/main/wifi_manager.h"

I'm now getting error:

...
.pioenvs/esp32dev/src/http_server.o:(.literal.http_server_netconn_serve+0x4c): undefined reference to `_binary_style_css_start'
collect2: error: ld returned 1 exit status
*** [.pioenvs/esp32dev/firmware.elf] Error 1

What am I doing wrong? It seems to me the assets couldn't be linked. Or it is just not yet capable for library use?
