| config BLUETOOTH_CONTROLLER_XTAL_ADVANCED |
| bool "Advanced event preparation" |
| default y |
| help |
| Enables advanced event preparation offset ahead of radio tx/rx, taking |
| into account predictive processing time requirements in preparation to |
| the event, like control procedure handling and CPU execution speeds. |
| Crystal oscillator is retained between closely spaced consecutive |
| radio events to reduce the overall number of crystal settling current |
| consumptions. |
| |
| This feature maximizes radio utilization in an average role event |
| timeslice when they are closely spaced by using a reduced offset |
| between preparation and radio event. |
| |
| By disabling this feature, the controller will use a constant offset |
| between the preparation and radio event. The controller will toggle |
| crystal oscillator between two closely spaced radio events leading to |
| higher average current due to increased number of crystal settling |
| current consumptions. |

| Configure the optimal delta in micro seconds between two consecutive |

| default n if BLUETOOTH_PERIPHERAL && !BLUETOOTH_CENTRAL |
| help |
| Enable non-overlapping placement of observer, initiator and master |
| roles in timespace. Uses window offset in connection updates and uses |
| connection parameter request in slave role to negotiate |
| non-overlapping placement with active master roles to avoid slave |
| roles drifting into active master roles in the local controller. |
| |
| This feature maximizes the average data transmission amongst active |
| concurrent master and slave connections while other observer, |
| initiator, master or slave roles are active in the local controller. |
| |
| Disabling this feature will lead to overlapping role in timespace |
| leading to skipped events amongst active roles. |

| Peripheral will respond to Encryption Request with Encryption Response |
| in the same connection interval, and also, will respond with Start |
| Encryption Response PDU in the 3rd connection interval, hence |
| completing encryption setup in 3 connection intervals. Encrypted data |
| would be transmitted as fast as in 3rd connection interval from the |
| connection establishment. |

| selected. |
