AES CCM on-the-fly encrypt/decrypt using ESB

[Julian]

Hi,

As per subject I am looking to implement hardware on-the-fly AES-CCM encryption/decryption of ESB packets. Are there any examples/guides available for the nRF52840?

I have started with the example provided @ https://github.com/NordicSemiconductor/nrf52-esb-ccm-example. However, the encrypt/decrypt process is not on-the-fly.

Any help much appreciated.

Hi,

I am not aware of any examples that demonstrate on-the-fly encryption/decryption with ESB. Generic on-the-fly encryption/decryption is described in detail in the CCM chapter in the product specification though, so you can use that as a reference if you are implementing it.
