+/**
+ *  Minimal configuration for using mbedtls as part of mbed-client
+ *
+ *  NOTE! This is an optimized, minimal configuration for mbed Client.
+ *  We know it works with mbed Client but if you want to add more
+ *  services/communications to the application yourself - please ensure
+ *  you update this configuration accordingly. The default configuration
+ *  can be found from mbedTLS Github:
+ *
+ *  https://github.com/ARMmbed/mbedtls/blob/development/include/mbedtls/config.h
