Hi,
According to latest OMA-TS-LightweightM2M-V1_0-20170208, when using
PSK mode it is recommended  to provision a 16 byte (128 bit) key or
longer in the Secret Key Resource.
Currently wakaama is using tinydtls library for security which limits
the key to 16 bytes length (DTLS_KEY_LENGTH 16).
Is it possible to increase this value?

Thanks,
Boris Shlafman
