@dwhire A similar problem also exists when using the Arduino IDE. e.g. SimpleWiFiServer.ino. I have raised a repair ticket on Banggood (My supplier)

Device: LILYGO TTGO T-OI PLUS RISC-V ESP32-C3
Dev Environment: ESP-IDF 4.3
Program: examples\wifi\getting_started\station (unmodified)
The WIFI station example program does not work on this device.
The same is true for the softAP example. Please assist in finding a solution.

The program was run exactly as it is provided in the IDF installation.
idf.py set-target esp32c3 was applied.
I can confirm that this example program runs OK without change on my M5Stack which is standard ESP32.
