How to use the sd_ecb_block_encrypt API?

[balaji]

Hi, Is there any sample code which is using the sd_ecb_block_encrypt(); API, we are planning to do encryption and decryption of data, which will be transmitted and received over the air, So it will be helpful for us, if we get any source code regarding this.

Regards, Balaji

Hi Balaji

If you are using BLE then you don't need to use the sd_ecb_block_encrypt() function manually. As long as you enable security on the required characteristics, and you bond with the BLE master, the BLE stack will encrypt/decrypt the data for you.

Thanks for your reply Torbjorn, what do mean by enabling the security on the required characteristics? I never tried anything like this before, if possible suggest me how to do this.
