I am using a nordic BLE SOC: nrf52 dk, along with s130 and sdk 14.2.0 I want to secure an advertised BLE packet with AES CCM encryption. The board contains a co-processor for AES calculation that is not accessible while using the soft device that I am using to generate packets and advertise.
The solution is to use timeslot API but I do not know how to do it. There is a tutorial but it's only valid for nRF5 SDK 11.
