Got the following errors while trying to compile for ESP32 (brand new install of ESP-IDF, version v4.4.1):

Solved this by setting CONFIG_WPA_MBEDTLS_CRYPTO=n (in idf.py menuconfig, Component config -> Supplicant -> Disable Use MbedTLS crypto APIs), so dropping this here mostly for information in case others run into the same issue.

Thank you! It's worked out for me.
