Expected behavior

I have a commercial device with a ESP32-S3 that can connect to a wifi access point. I set up an access point with a Raspberry Pi 4B (Bookworm 64bit OS) which uses a Broadcom BCM43438 chip for wifi. I expected that the ESP32-S3 can connect to the wifi network supplied by the Raspberry Pi.

Actual behavior (suspected bug)

The ESP32-S3 device was unable to connect to the the access point provided by the RaspPis internal wifi (Broadcom BCM43438). To verify the access point is working, I establised a connection to it with my smartphone.
When I use a USB wifi stick (Qualcomm Atheros AR9271 chip) with the RaspPi to set up the access point, the wifi connection between ESP32-S3 and RasPi functions as expected.
