Optimal energy settings for T-Beam 1.1

Has anyone researched optimal power settings for the T-Beam?

I would like to use the several boards via Bluetooth with Android as a client and one should work autonomously as a repeater.

Messages are only lost when the ESP32 is in Super Sleep. In Light Sleep the ESP32 wakes up and processes the received message? Right?

Correct. See behavior in the docs here
