Bluetooth Power Save Example
=================================

In sleep state, RF, PHY and BB are turned off in order to reduce power consumption.
This example contains five build configurations. For each configuration, a few configuration options are set:
- `sdkconfig.defaults.esp32`: ESP32 uses 32kHz XTAL as low power clock in light sleep enabled.
- `sdkconfig.40m.esp32c3`: ESP32C3 uses 32kHz XTAL as low power clock in light sleep enabled.
- `sdkconfig.esp32c3_40m`: ESP32C3 uses main XTAL as low power clock in light sleep enabled.

- `sdkconfig.40m.esp32c3`: ESP32C3 uses main XTAL as low power clock in light sleep enabled.
- `sdkconfig.defaults.esp32c6`: ESP32C6 uses 32kHz XTAL as low power clock in light sleep enabled.
- `sdkconfig.40m.esp32c6`: ESP32C6 uses main XTAL as low power clock in light sleep enabled.
- `sdkconfig.defaults.esp32s3`: ESP32S3 uses 32kHz XTAL as low power clock in light sleep enabled.

## How to use example
### Hardware Required
This example should be able to run on any commonly available ESP32/ESP32-C3/ESP32-S3/ESP32-H2 development board.
