Is it possible to modify BLE_CONN_CFG_GAP after the softdevice has been enabled? I want to be able to set the event length on start up based on a setting stored in flash with FDS, but I can't use FDS until the softdevice is enabled since FDS uses the soft device back end. If it can't be modified after the softdevice is enabled would the best solution be to enable the softdevice, read the setting, disable the softdevice and then re-enable it with the updated setting?
