00002  *  Minimal configuration for using mbedtls as part of mbed-client
00003  *
00004  *  NOTE! This is an optimized, minimal configuration for mbed Client.
00005  *  We know it works with mbed Client but if you want to add more
00006  *  services/communications to the application yourself - please ensure
00007  *  you update this configuration accordingly. The default configuration
00008  *  can be found from mbedTLS Github:
