Compilation Error, undeclared frame and wifi

Arduino IDE v2.3.4 (2024-12-03) Board: DOIT ESP32 DEVKITV1

Just cloned the repository today and tried to compile the code. Getting the below listed errors.

I'm getting the same error and while the PR from @cdamman fixes the FAN_FRAME error, I also get the WiFi errors I see in your message when using my ESP32 DEV board and the PR doesn't fix that unfortunately. So if anyone knows hw to fix that part, I'm very interested

same errors here weeks ago. I've removed the FAN_FRAME_04 code part (put case FAN_FRAME_04 in comment) and included wifi....h files include in numerous files, then it compiled completely. Added :

#include <WiFi.h>

to : /nRF905API.ino /api/json_api_v1.cpp /html/configwizard.cpp /html/html.cpp /hardware/esp32.cpp

also had to change in /hardware/esp32.cpp :

String Board::get_localIPv6(void) {
	return WiFi.localIP().toString();
}
bool Board::enable_IPv6(void) {
	return WiFi.enableIPv6();
}

Best is that the project owner fixes this in main branch.

@8OND007 Thanks for your reply, I got it to work perfectly by combining the PR by @cdamman with your changes. So thank you very much!

Hello, just got an ESP32 board 🙂 Pushed the fix in my PR as well! https://github.com/eelcohn/nRF905-API/pull/33/commits/9e9b9406a76b4302cfc1eda17155121884944a9b
