nrf52: after disconnect, device doesn't go into sleep again #9276
BLE_HeartRate example, release profile, advertising interval changed to 250ms: during advertising, the current consumption is about 76uA. Once connected the controller keeps alive (I don't know if that's normal) and draws a little more then 3.3mA. But once disconnected, it still draws 3.3mA. Furthermore the spike while sending the advertisement packet is much higher (around 9mA compared to 6.5mA).

@bearsh Thanks for pointing this out and we noticed it ourselves while investigating #9093. We have shown that this is related to the CryptoCell 310 (CC310), and @pan- has an idea to resolve it. The higher current floor we observe related to using the CC310 (mentioned in #9093) needs to be re-evaluated.
