BLE reconnect time from light sleep takes long.

Hello, and thanks in advance for looking at the question.
I am trying to construct a BLE keyboard using the T-vK library(https://github.com/T-vK/ESP32-BLE-Keyboard). To save power I put it into light sleep after no input is detected for a couple of seconds. However, I'm seeing that it takes ~1-2 seconds for the bluetooth to re-connect after waking up, which makes using this device clunky and awkward. Is there any way to speed this re-connect process up? If not, is it possible to stay connected while still achieving a relatively low power state?
