Establish Bluetooth connection in least amount of time

Hi everyone. I am trying to find the best way to establish a Bluetooth connection to a nRF52832 in the least amount of time.

I'm designing an ultra low power perpheral device which will remain in SYSTEMOFF mode until reset by an external watchdog every 10s. At this point the nRF52832 will advertise using the bluetooth and if no central bluetooth device is present go back to SYSTEMOFF. What is the best way to reduce this wake period?

Currently I'm using a device programmed with the peripheral blinky example and another device programmed with the central blinky example and from the point of advertisement to the point of connection I am getting results of about 33ms.
