On the infocenter website we can read that ,,The nRF5 SDK v15.0.0 supports nRF52 Series devices''. I would like to use crypto code from SDK15 on nRF51. I am interested in using AEAD GCM/CCM. By ,,work' I would like to know if these algorithms are also accelerated in hardware on nRF51, so that encryption time is about 200 us?
