WiFi STA does not connect and WiFi AP does not advertise

FYI, you have to use LVGL version 8.4.0 with the included lv_conf.h file, not the latest version of LVGL.

Another issue, is that i can scan for WiFi networks and see my target network - Great. But when i come to connect to the AP, it will only show "Wifi disconnected". Using esp_wifi.h and the error logging available in this library, the log states it wont connect due to "wifi_event_sta_disconnected_t reason 2" - the target AP cannot be found. Talking with chatGPT, I think this is due to the LCD screen interfering with the directional nature the the C3 ceramic patch antenna. Even when my AP is 2cm from the antenna, it will not connect. Using the same program on a ESP32-S3-Zero, the device connects to the AP just fine.

I have also noticed that if you try to get the device to be an AP, you cannot see the SSID with my phone, right next to it or with any other devices?

Any ideas?
