Help¶

Use a specific mbedTLS configuration file. The default config file file can be tweaked with Kconfig. The default configuration is suitable to communicate with majority of HTTPS servers on the Internet, but has relatively many features enabled. To optimize resources for special TLS usage, use available Kconfig options, or select an alternative config.

Direct dependencies¶

NORDIC_SECURITY_BACKEND || (MBEDTLS_BUILTIN && MBEDTLS)
