config MBEDTLS_SSL_MAX_CONTENT_LEN
int "TLS maximum message content length"
default 16384
range 512 16384
help
Maximum TLS message length (in bytes) supported by mbedTLS.
16384 is the default and this value is required to comply
fully with TLS standards.
However you can set a lower value in order to save RAM. This
is safe if the other end of the connection supports Maximum
Fragment Length Negotiation Extension (max_fragment_length,
see RFC6066) or you know for certain that it will never send a
message longer than a certain number of bytes.
If the value is set too low, symptoms are a failed TLS
handshake or a return value of MBEDTLS_ERR_SSL_INVALID_RECORD
(-0x7200).
config MBEDTLS_DEBUG
bool "Enable mbedTLS debugging"
default "no"
help
Enable mbedTLS debugging functions.
If this option is enabled, use the mbedtls_debug_set_threshold()
and mbedtls_ssl_conf_dbg() functions to obtain debugging output
from mbedTLS.
Note thatm mbedTLS debugging is not related to the ESP logging
functionality. See the "https_request_main" example for a
sample function which connects the two together.
