CONFIG_MBEDTLS_HEAP_SIZE

The mbedtls routines will use this heap if enabled. See ext/lib/crypto/mbedtls/include/mbedtls/config.h and MBEDTLS_MEMORY_BUFFER_ALLOC_C option for details. That option is not enabled by default. Default value for the heap size is not set as it depends on the application. For server application 15000 bytes should be enough. For some dedicated and specific usage of mbedtls API, the 1000 bytes might be ok.
