I've just received some ESP32-S3 boards from a seller on Aliexpress.
The WiFi scanner sketch work OK and the RSSI values look sensible.
However if you run a sketch that tries to connect to an access point it goes through
SYSTEM_EVENT_WIFI_READY,
SYSTEM_EVENT_STA_START.
then just generates a SYSTEM_EVENT_STA_DISCONNECTED event every second in a perpetual loop.
If you then briefly touch the corner of the patch antenna with your finger , it generates a SYSTEM_EVENT_STA_GOT_IP event and resumes normal operation.
Has anyone seen weird behavior like this?
