AES hardware module

[Greebo]

We've been trying to user the AES hardware module in ECB mode. To do that we used the sd_ecb_block_encrypt function.

Is this hardware accelerated? Based on power consumption it seems that it is a software implementation. If it is not hardware accelerated, how can we use the hardware module.

Thanks!

Yes, that should be HW accelerated but may get delayed if you are using encryption in your BLE connection and are actively transferring data. Said another way, you're sharing that HW block with the SoftDevice.

What do you mean by "based on power consumption"? Is it greater than what you would expect for a HW implementation?
