# This example is disabled as mbedtls uses too much stack, and Freertos SMP is problematic with
# pico_cyw43_arch_lwip_threadsafe_background (nosys), where WiFi and LwIP activity is performed in an IRQ.
# Prefer to use pico_cyw43_arch_lwip_sys_freertos instead, where WiFi and LwIP activity is performed in a thread.
