WPA2-Enterprise Connection

[Zubs01]

Does anyone here have experience with using WPA2-Enterprise (SSID/Username/password) for this project? As the code explanations are all mainly WPA2-Personal(SSID & Password). I am interested to know what I need to change in the code to make this possible if anyone is knowledgeable about the topic. Thank you so much to anyone that can help

You would have to check the ESP IDF documentation to see if this is supported at all. Then dig through https://github.com/jomjol/AI-on-the-edge-device/blob/main/code/components/jomjol_wlan/connect_wlan.cpp

From what ive seen online and from ChatGPT, ESP-IDF does support WPA2-Enterprise but ill need to change some code in jomjol_wlan, recompile it in ESP_IDF Windows Installer and flash the hardware again

@Zubs01 I don't know with WPA2-Enterprise and couldn't test it either:
https://github.com/SybexX/AI-on-the-edge-device/actions/runs/15098074900

e.g.

ssis = "test"
eapid = "[email protected]"
username = "test"
password = "test"

MQTT does not really matter whether the ESP32 connects to the router via WEP WAP or anything else, it simply uses the existing connection. Maybe the port used by MQTT is blocked on your router or the firewall from your laptop is blocking it?

[Zubs01]

I see, thank you for your reply SybexX! I will check the possible options on that. I also tried to use port forwarding from "Netsh Port Forwarding from LAN IP(172.xxxx.xx.xx)-Port(1883) to Local IP(127.0.0.1)-Port(1883) for Mosquitto MQTT Broker", to see if it could work.

But when I did that, it stopped showing the error below. Do you happen to know why? I will check the router / firewall as well tomorrow.

Here is the log after the latest reboot, it stops after the "[LOGFILE] Set log level to ERROR". The logs before this showed it kept trying to connect the MQTT.

If the MQTT connection does not come about after several attempts (I think it was 5x), the ESP32 restarts.

Hi @SybexX, I hope you are well. I realized that you deleted (cleaned) all your branches from the main code. (including test)

I've been slowly learning your code and the changes, and have been using your "commits/test" page as a reference. The page is sadly not there anymore. Is there a way I can still have access to the changes that you did, or is it permanently gone? If it is all gone, it is alright too. I did take down some notes already, but I was an idiot and did not clone your code changes into my computer.

In any case, you have helped me a lot by getting the ESP32CAM to connect using a WPA2-Enterprise network, and I am very grateful for that. 👍
