RPI4 wifi hotspot network manager connection issues -ESP32 won't connect at all.

ESP32 even supports WPA2 Enterprise but I used ChatGPT to help with enforcing WPA2-AES (psk) on the Pi - which my iPad will be happy about as well hopefully ### Updated Configuration Edit your /etc/NetworkManager/system-connections/wifi-hotspot.nmconnection file as follows: [wifi-security] key-mgmt=wpa-psk proto=rsn pairwise=ccmp group=ccmp psk=YourSecurePassword

### Explanation:
- `proto=rsn`: This specifies WPA2 (the modern standard).
- `pairwise=ccmp`: Forces AES for unicast traffic.
- `group=ccmp`: Forces AES for group traffic (broadcast/multicast).

### Restart and Activate the Hotspot
After saving the changes, restart NetworkManager and bring up the hotspot again:


sudo systemctl restart NetworkManager
nmcli connection up wifi-hotspot

Reset pin pressed, when booting the ESP32 and it finally connected. *
