Port, board and/or hardware

ESP32-C3 and S3

MicroPython version

MicroPython v1.25.0 on 2025-04-15; ESP32C3 module with ESP32C3

Reproduction

Power-cycle the board and run the following code (in my case, in Thonny):

import network, time
sta_if = network.WLAN(network.WLAN.IF_STA)
sta_if.active(True)

print('foo')
sta_if.connect("no-such-network", "password")
time.sleep(5)

print('bar')
sta_if.connect("no-such-network", "password")
time.sleep(5)

print('baz')

Expected behaviour

No response

Observed behaviour

foo
bar
Traceback (most recent call last):
  File "<stdin>", line 10, in <module>
OSError: Wifi Internal Error

(where line 10 is the second connect)

I get similar results when the first connect() is a real network with the wrong password, the second connect() is the same wrong network/password as the first, or the second connect() is a real network with the right password.

In fact, the sleep()s don't seem to be required either.

Additional Information

Power-cycling the board before running the test may be required for reproducibility.

Bug also manifests in the latest preview ESP32_GENERIC_C3-20250709-v1.26.0-preview.364.gdf05caea6.bin

and ESP32_GENERIC_S3-SPIRAM_OCT-20250709-v1.26.0-preview.364.gdf05caea6.bin

Unfortunately I don't have other boards to test with right now.
