Is there any way I can turn on and off the device at specific time or make it in a low power mode to save battery life?

Hello,

What do you mean turn on/off the device ?

For the low power part you can start with an example from the STM32Cube_FW_L4.

Being able to turn on like once per hour and then turn off after few minutes

Additional question. For the lower power part. Does the lower part disables the Bluetooth functionality or it is still running at low power? for st products with Bluetooth functionally

Hello,

>Being able to turn on like once per hour and then turn off after few minutes :

You can configure a timer to wake up the MCU each period of time.

For the second part :

It depends on the product capabilities at low power modes.

You can refer to this series STM32WB for more details.
