How to realize nRF24LE1 AES decryption

[dreamk]

I've been using nRF24LE1 for development. The HAL library provide the AES encryption for ECB mode. Now I need the decryption function. Does anyone has the realization? Any information will be appreciated!!!

Hi,

The AES HW inside the LE1 lacks some features, meaning that most of the processing must be done by the MCU. We have a couple of libraries for AES (hal_aes, lib_crypt). I am attaching a small example which uses AES Counter mode in combination with the radio.

Best regards Håkon

Ok! How to implement the decoding of the pair nRF24LU1P/LE1 AES? There are examples? Thank You!
