Hello,

Can't find any documentation how to deinit httpd instance, it causes StoreProhibited error wen trying to esp_wifi_stop(); and esp_wifi_deinit(); after httpdFreertosStart was called, resulting in no possibility to turn off wifi dynamically with httpd server.

Hi,

I have just started to learn how to use the esp32. This project would be a great help.
So I tried to build it on windows 10 using esp-idf 4.0 stable. My setup seems to work correctly with other projects and examples.

Running idf.py build on this one, the first issue was:

[665/686] Performing install step for 'mkespfsimage'
[0/1] Install the project...
-- Install configuration: ""

'npm' is not recognized as an internal or external command,
operable program or batch file.
ninja: build stopped: subcommand failed.
ninja failed with exit code 1

Fixed it by installing: https://nodejs.org/en/
Unfortunately I got stuck at the following:

ninja: build stopped: subcommand failed.
ninja failed with exit code 1

As I just started to learn esp32 stuff and I am not an experienced c++ / linux programmer I don't know how to fix that one.
My guess is that the cmake scripts use linux commands.
I am a bit sad about it since the esphttpd library seems to be just what I was looking for. Also this example seems very usefull.

I would really appreciate your advise.
Egon :-)

In the ROUTE_REDIRECTs below, was it intended that the second one should instead be ROUTE_REDIRECT("/test/", "/test/index.html"),?

Lines 173..175 in user_main.c

	ROUTE_REDIRECT("/test", "/test/index.html"),
	ROUTE_REDIRECT("/test", "/test/index.html"),
	ROUTE_CGI("/test/test.cgi", cgiTestbed),

I can not get the stock project to compile targeting the ESP32. I am using git commit 2cd29cb of this project and the release/v4.0 branch of the ESP-IDF @ 463a9d8.

Procedure to reproduce:

1. Clone the repository, cd into the new folder and run the git submodule update command specified in the README
2. Run make
3. Once the 'menuconfig' menu appears, change nothing, just save the default config and exit

The following error will occur:

An OTA update seems to fail 50% of the time when performed over WiFi. It almost never fails via Ethernet.

Usually the WiFi connection to the esp AP disappears from my phone, then my phone tries to connect to another AP. So it seems the WiFi is unstable during the flashing process.
Has anyone else experienced this?

Perhaps it can be improved by yielding more time from the flash operation to the WiFi functions?

I get this as soon as I try and build;

How can I get this script to use double backslashes or a forward slash? This should be mandatory in the build script to catch Windows environments

Hi there,

I'm trying to separate the webpage data into a different 8MB partition. I sadly running into the same problem with the size of the filesystem (ESP_ERR_NO_MEM) than in following topic:
espressif/esp-idf#1184

Does anyone has a workaround for this or are there any examples available for how to adapt a SPIFFS fs with the esphttpd-freertos example?
Thanks,

Hello, using latest esp-idf and latest libesphttpd this example does nothing, monitor says everything is ok, but trying to connect via browser or telnet, 80 port is timing out. Monitor:

Hi,
I am using ESP-IDF v4.1, the application compiles and flashes correctly, however selecting perform OTA firmware does nothing, it does not display the partitions table, nor does it accept to reboot!
Apperantly the cgiGetFlashInfo is not called due to bad java script in html file, cannot read localStorage!

Thanks,

Trying to run git clone, I get the following; any suggestions? Similar error on Linux. Thanks.

Hi I am trying to compile your example code in platformio and get the following error
Compiling .pio\build\esp32doit-devkit-v1\esp-idf\espfs\src\espfs.c.o
*** [.pio\build\esp32doit-devkit-v1.pio\build\esp32doit-devkit-v1\esp-idf\espfs\src\espfs_image.c.o] Source .pio\build\esp32doit-devkit-v1\esp-idf\espfs\src\espfs_image.c' not found, needed by target .pio\build\esp32doit-devkit-v1.pio\build\esp32doit-devkit-v1\esp-idf\espfs\src\espfs_image.c.o'.

I have no idea what that means and how to fix it, some guidance would be greatly appreciated

There is an assertion failure on line 284 in file main/user_main.c when ever attempting to switch to standalone STA mode. This issue is seen in git commit #ffffd5c.

Instructions to reproduce:

1. On an ESP32, Checkout, compile, flash, and monitor version #ffffd5c.
2. Connect to the 'ESP' WiFi AP, browse to http://192.168.4.1, and select 'Configure your WIFI Network' option.
3. Click on the 'Go to AP+STA mode' button. Wait for the screen to refresh.
4. Enter your SSID (or click the scan button and select your SSID), enter your password, and click on the 'Connect!' button. After the screen has changed, click on the 'here' button to use the ESP's new IP address.
5. Re-select 'Configure your WIFI Network' option.
6. Click on the "Go to standalone STA mode' button, The esp will assert on line 284 in file main/user_main.c

Additional Information:
Modifying line 284 from:

ESP_ERROR_CHECK( esp_wifi_ap_get_sta_list(&sta_list));

to

esp_wifi_ap_get_sta_list(&sta_list);

apparently makes the software work, but I am too new to this project to know if this is the correct way to fix this issue.

Also, the error return from function esp_wifi_ap_get_sta_list is ESP_ERR_WIFI_MODE (0x305) and
sta_list.num is equal to 1 upon this functions return.

There are a couple of comments on build the project

Initialization of submodules.

After cloning the repository and initializing the submodules:

git submodule update --init --recursive

There are no latest commits in the "espfs" and "libesphttpd" submodules (this can be seen by looking at the log of the submodules), so the project not build. If updating submodules from remote:

git submodule update --init --recursive --remote

The latest commits appear in the "espfs" and "libesphttpd" submodules. But a build error occurs on the "heatshrink" submodule. To get the necessary commits in all submodules, needed to run two commands:

git submodule update --init --recursive
git submodule update --remote

After such initialization, the project for ESP32 ESP-IDF (master) is built without problems.

Build the project for ESP8266.

I managed to build and run this project for ESP8266 ESP8266_RTOS_SDK (master). But it was necessary to change the code of the project and the submodules "espfs", "libesphttpd". As I understand it, the old SDK was used for the ESP8266.
For example, in the file "components/libesphttpd/include/libesphttpd/esp.h":

#ifdef ESP_PLATFORM // only set in esp-idf
#define FREERTOS 1
#define ESP32 1
...

The assumption that "ESP_PLATFORM" declared only in ESP-IDF is not true.
For which version of the ESP8266 SDK is a project build expected?

After flashing the firmware, I can successfully connect to 192.168.4.1, associate the ESP to my WiFi network. All the pages work.

If I switch to STA Mode only and reboot, I can no longer ping the ESP.

I am using esp-idf v4.0
