Error: missing ‘softAPSubnetMask’ in WiFiClass (ESP32 / Artnet)

[arpschuino]

Hi,
I’m switching from version 0.2.8 to 0.9.2.
I made all the required modifications (I think), but my code doesn’t compile.
Here’s the error message:
.pio/libdeps/esp32doit-devkit-v1/ArtNet/ArtnetWiFi.h:58:25: error: 'using ArtnetWiFiClass = class WiFiClass' {aka 'class WiFiClass'} has no member named 'softAPSubnetMask'; did you mean 'softAPSubnetCIDR'?

thank you in advance.

[arpschuino]

It seems that the latest ESP32 Arduino core removed softAPSubnetMask() in favor of softAPSubnetCIDR(). I was able to fix the problem locally by replacing all occurrences of softAPSubnetMask() with softAPSubnetCIDR().

I wanted to report this so it can be addressed in a future release of the library, ensuring compatibility with the latest ESP32 core.

Thanks again for your work on ArtNet!

[hideakitai]

@arpschuino Thank you for reporting. But softAPSubnetMask() is still available in the latest main branch of arduino-esp32.

Also, I could compile the examples using the latest arduino-esp32 with several ESP32 series as shown in CI (e.g. ESP32).

Could you confirm your own code and target board/platform?

[arpschuino]

Well, this is the content of my platformio.ini:

[env:esp32doit-devkit-v1]
platform = espressif32
board = esp32doit-devkit-v1
framework = arduino
monitor_speed = 115200
board_build.partitions = my_partitions.csv
monitor_rts = 0
monitor_dtr = 0
lib_deps = 
    ESP32Async/ESPAsyncWebServer @ ^3.6.0
    hideakitai/ArtNet@^0.9.2
    roboticsbrno/ServoESP32@1.0.3
    someweisguy/esp_dmx@^2.0.2
    adafruit/Adafruit PWM Servo Driver Library@^2.4.1
    adafruit/Adafruit NeoPixel@^1.11.0

;   Special retrofit :
    paulstoffregen/OneWire@^2.3.8
    milesburton/DallasTemperature@^3.11.0

should it help ?

[arpschuino]

I'm using an Arpschuino32, a board I developed myself:
https://arpschuino.fr/arpschuino32_e.php
It's equipped with a standard ESP32 4MB (ESP32-WROOM-32E-N4)

[hideakitai]

Could you please provide a minimal project that reproduces the error?

[arpschuino]

Thank you very much for your quick response!
Here is the link to download my code:
https://nextcloud.arpschuino.fr/index.php/s/Y4C8ZzQfi4Rj8bd

[hideakitai]

I couldn't reproduce it. Could you give me a COMPILABLE, MINIMUM, and REPRODUCIBLE project?

[arpschuino]

Sorry...
I see that the compiler can't find arpschuino.h.
It's a case sensitivity issue; the file is present but with a capital letter: Arpschuino.h. It compiles fine for me like that, but it must be a matter of an option in VS Code or PIO.
Anyway, I've corrected this in retrofit_1.4.2.2.3-Copy, so if you download it again it should be OK.

[arpschuino]

Furthermore, I searched for the WiFiAP.h file in my copy of the code, but for some unknown reason it's not the same version as the one you linked to.
It seems older; there are fewer lines of code.
However, in platformio.ini I wrote platform = espressif32, so the latest version should have been downloaded.

[hideakitai]

I couldn't reproduce it. Could you please provide the code after confirming that only the softAPSubnetMask compile error you mentioned occurs reliably on your end?

I would prefer you create a minimal project that reproduces the softAPSubnetMask error with only ArtNet as a dependency, rather than sending me your entire project.

Hello,
Here’s what I did:

In my main file, I copied the content of your example send_receive.ino

I deleted all the other files

In platformio.ini, I removed calls to other libraries

I did a full clean

I recompiled

Here’s the error message I’m getting:
