## ◆ ble_activity_end_notify_cb_register()

void ble_activity_end_notify_cb_register | ( | void(*)(ble_gap_actv_role_t e_role, uint8_t index) | callback | ) |

Register BLE activity end notification callback function.

Parameters

  [in] | callback | function pointer of BLE activity end notification function.

Note
  e_role: the role of activity, refer to ble_gap_actv_role_t for possible roles. index: The index parameter is interpreted by role. If role is BLE_GAP_ACTIVITY_ROLE_ADV, it's the index of Advertising. If role is BLE_GAP_ACTIVITY_ROLE_CON, it's the index of Connection. For all other roles, it should be ignored. Callback will be called by BLE ISR when the BLE activity ends every time. It should be realized as simlpe as you can. You'd better to define it in the RAM space It's not suitable for ISO activities.
