What happened?

When building AsyncTCP for the ESP32-P4 with custom_sdkconfig set (even without any options), compilation fails due to mismatched types between [ip_addr] and [ip_addr_t].

To Reproduce use AsyncTCP as a dependency in a PlatformIO project targeting ESP32-P4 and set custom_sdkconfig.
Build the project.

I confirm that:

I have read the documentation.
I have searched for similar discussions.
I have searched for similar issues.
I have looked at the examples.
I have upgraded to the lasted version of AsyncTCP.

Hi,
Did you try with v3.4.1 ?
Did you also try with esp32dev board (with v3.4.1 and with v3.4.3) ?

I am not able to reproduce. If I create a pio file with your content and create src/main.cpp with your c++ content and run pio run on CLI, I get :

After testing many settings, different boards and Async versions, I discovered that PlatformIO/Arduino doesn't seem to clear the build cache properly (or at least that's what it looks like). Sometimes a build works correctly, and other times it doesn’t—seemingly at random.

When manually deleting all cache/temp files in the project folder:
Folders:

.dummy
managed_components
.pio/build
.pio/libdeps

Files:

sdkconfig.defaults
sdkconfig.esp32-p4
CMakeLists.txt
dependencies.lock

And these settings, it will compile.

board = esp32-p4
ESP32Async/AsyncTCP


custom_sdkconfig = 
  ; CONFIG_LWIP_IPV6=n 
  ; CONFIG_LWIP_IPV6_AUTOCONFIG=n
  ; CONFIG_LWIP_PPP_SUPPORT=n
  ; CONFIG_BT_ENABLED=n
  ; CONFIG_CACHE_L2_CACHE_256KB=y
  ; CONFIG_ESPTOOLPY_FLASHFREQ_80M=y
   CONFIG_LIBC_OPTIMIZED_MISALIGNED_ACCESS=y  
   CONFIG_LWIP_IRAM_OPTIMIZATION=y
   CONFIG_ETH_IRAM_OPTIMIZATION=y
   CONFIG_ESP_MAIN_TASK_STACK_SIZE=7168  
   CONFIG_COMPILER_OPTIMIZATION_PERF=y

But disabling IPV6 support by uncommenting
CONFIG_LWIP_IPV6=n

Will produce the ip_addr_t error.
.pio/libdeps/esp32-p4/AsyncTCP/src/AsyncTCP.cpp:313:27: error: cannot convert 'ip_addr_t*' {aka 'ip4_addr*'} to 'ip_addr*' e->client->_dns_found(&e->dns.addr); ^~~~~~~~~~~~ ip_addr_t* {aka ip4_addr*} .pio/libdeps/esp32-p4/AsyncTCP/src/AsyncTCP.cpp:527:34: error: invalid application of 'sizeof' to incomplete type 'ip_addr' memcpy(&e->dns.addr, ipaddr, sizeof(struct ip_addr)); ^~~~~~~~~~~~~~~~~~~~ .pio/libdeps/esp32-p4/AsyncTCP/src/AsyncTCP.cpp:1164:12: error: no matching function for call to 'AsyncClient::connect(ip_addr&, uint16_t&)' connect(*ipaddr, _connect_port); ^~~~~~~~~~~~~~~~~~~~~

After an error, no other options, lib_deps or boards will compile. You need to manually clear all the caches & temp files.

To summarize for AsyncTCP:

It will not compile with these platformio settings:

[env:esp32-p4]
platform = https://github.com/pioarduino/platform-espressif32.git
lib_compat_mode = strict
lib_ldf_mode = chain

framework = arduino
board = esp32-p4
;board = esp32dev
;board = esp32-p4-evboard
build_flags = -D CORE_DEBUG_LEVEL=5
monitor_speed = 115200

custom_sdkconfig = 
   CONFIG_LWIP_IPV6=n 

  

custom_component_remove = espressif/esp_hosted
                          espressif/esp_wifi_remote
                          espressif/mdns
                          espressif/esp-dsp
                          espressif/esp_modem
                          espressif/esp32-camera

lib_deps =  
  ESP32Async/AsyncTCP

I suspect CONFIG_LWIP_IPV6 is required... Even Arduino 2 has it set and AsyncTCP is for Arduino 2 and 3. It was recently opened to esp-idf only but not sure it can be used with CONFIG_LWIP_IPV6=n, especially with framework = arduino.

Maybe @willmmiles or @me-no-dev would know better...

I will move this to support ticket for now, until it is proven there is a real issue which is not related to a usage problem.

@qniens : would you be able to test this PR ? #68
I have removed ref to the structure to use the type ip_addr _t directly (which is redefined depending on the config).
This is more correct IMO but not sure it will solve the issue.

@mathieucarbou I just tested the PR and it compiles without errors.

It looks like this quick fix might make it incompatible with ESPAsyncWebServer.

Leaving the built cache intact and only including
https://github.com/ESP32Async/ESPAsyncWebServer.git
It will also produce errors on the just changed ip_addr struct.

@qniens : the error you got in espasyncws (first one with the fix) is unrelated. I've seen that: this is because you miss an include and Arduino components are then missing from the compile path.

you can add includes or maybe:

  ESP32 Async UDP
  ESPmDNS
  FS

  WiFi

You are correct. If you don't include ESPAsyncWebServer.h in your code it will throw errors.

#include <Arduino.h>
//#include <ESPAsyncWebServer.h> //Not including this will throw errors.
void setup(){

}

void loop(){
    log_d("Hello, World!");
    vTaskDelay(1000); // Delay for 1 second

A minimal code example gives the same error.

#include <WiFi.h>
#include <ESPAsyncWebServer.h> 
void setup(){

}

void loop(){
    log_d("Hello, World!");

I think this is related to the custom_sdkconfig built of pioarduino in combination with the ESP32-P4.

Explainable since P4 has no WiFi so trying to use IP settings will fail.

The ESP32-P4 lacks Wi-Fi but includes an Ethernet PHY.
So why does it still compile when the custom_sdkconfig is disabled?
Shouldn't it fail to compile in that case too?

It compiles with these settings:

@qniens : so your problem is solved then ?

No, because I would like to use the custom_sdkconfig options. But I think this is no longer related to the AsyncTCP lib.
If you want you can close this issue and I will open it on the pioarduino git. Thank you for your support!

@qniens By using 'custom_sdkconfig` options you have to take care by using it correctly. As already explained before it needs taken care how to use options which affects wifi too. To be clear this is NOT a bug in pioarduino. Wrong config ends in compile errors. That's it.

If you want that custom of build, you can look into using Arduino as IDF component. On other side it's very hard for the Async libs to support both Arduino 2.x and 3.x. Once 2.x support is removed, things will get easier.

Thanks for the clarification ,I understand it's not a bug in pioarduino.

That said, I assumed that using a custom_sdkconfig would only override the values I explicitly set, and that all other values would remain the same as in the default build. But from what I’m seeing, it seems the resulting config doesn't fully match the default one.

If so, that explains the confusion. Thanks again for your time and support!

@qniens Will have a look, indeed only the setting which is listed in custom_sdkconfig should be changed to the original used sdkconfig (which is stored in the Arduino framework and used by pioarduino)

@mathieucarbou @qniens

The P4 env needs a change

[env:esp32-p4]
platform = espressif32
framework = arduino
board = esp32-p4
build_flags = -DLED_BUILTIN=2
monitor_speed = 115200
lib_deps =                https://github.com/ESP32Async/AsyncTCP.git
                          https://github.com/ESP32Async/ESPAsyncWebServer.git
custom_sdkconfig =        CONFIG_ESP_HOST_WIFI_ENABLED=y
                          CONFIG_ESP_MAIN_TASK_STACK_SIZE=7168

The key is to enable Host wifi for the P4. Now ESPAsyncWebServer throws an error

.pio/libdeps/esp32-p4/ESPAsyncWebServer/src/WebServer.cpp:11:10: error: 'WiFi' was not declared in this scope
   11 |   return WiFi.localIP() == request->client()->localIP();
      |          ^~~~

   19 |   return WiFi.localIP() != request->client()->localIP();
      |          ^~~~

This line https://github.com/ESP32Async/ESPAsyncWebServer/blob/c25ff116ab0ee917b43ade6156e3bac9e7e80611/src/WebServer.cpp#L10 (probably other too) needs a specifi check for the P4 which Network is used Wifi / ETH

@me-no-dev these are the lines we wanted to remove - that's the only place we depend on WiFi...

maybe it is time to refactor this part ?

These filters could for example only be compiled if WiFi.h is there maybe ?

Jason2866 · 2025-06-05T11:20:33Z

@mathieucarbou Why is this there at all? Imho this code part should not do WiFi enable at all, only a check for a valid IP in general.

I agree! Ask the question to the original lib author (@me-no-dev). These filters are here since a very long time and are now becoming a pain.

Filters are to be reworked once only ESP32 Arduino v3 is supported. Then we should use the Network layer to filter interfaces

Do you have an idea of when only ESP32 Arduino v3 will be supported? That would help us plan accordingly.

@me-no-dev This option CONFIG_ESP_HOST_WIFI_ENABLED=y should imho default set in Arduino Lib Builder for the P4

I'm not sure that is true. Seems to be an older option for something else

When compiling Arduino as a component of IDF and using this lib it fails to compile when this option is not set.

Yes, it automatically resolves the dependencies from the idf_component.yml which is in framework
