AES CCM encryption/decryption examples

[Lucas]

Hello,

Are there examples of AES CCM encryption/decription?

Is there a recommended procedure for generating nounces?

Are there recommended procedures for using CCM?

Thank you.

Update: I forgot to mention I am using a nrf52832.

Hello Oliver,

Thanks,

It seems this cryptocell is only available for nrf52840.

Are there any examples using the peripheral included in nrf52832?

Thank you for your help.

In this answer : devzone.nordicsemi.com/.../

we can read that :

Just Works: STK generated on both sides, based on packets sent in plain text. No security against MITM attacks

If I'm working with SDK11 on S132 then the link is encrypted in the Heart Rate Sensor example ?

If I enable the LE Secure Connections it's impossible to sniff data ?
