Troubleshooting • Can't connect to Wifi Hotspot with ESP32 Arduino Uno R4 to Raspi4 or Raspi5

Hello,

I've created a Wifi hotspot on a RaspBerry Pi 5 using the network manager GUI.

I can connect my phone or my computer on this hotspot but I can't with an ESP32 or an Arduino Uno R4. The 2 a reusing an ESP32 processor
I can view the Wifi hotspot with Arduio UNO R4 when I scan the available network but it is not possible to be connected on.

I can find a work around with the ESP32, to limit the security level to WPA-PSK in place of the default WPA2-PSK security level.

How to solve this trouble and permit WPA2 security level to be usable ?

Thanks in advance
