Low power with serial monitor

Hello everybody!
I'm trying to automate my campervan with an arduino 101 in order to communicate directly with it via BLE. As the Arduino in permantly connected to the battery car, I try not to drain to much current.

I use the Arduino101Power from here: GitHub - bigdinotech/Arduino101Power: Low Power Library for Arduino101

My problem is the following. I cannot use the Serial at the same time as the this library. When the arduino starts to sleep for 1 second ( PM.sleep(1000) ), It does not wake up for ever. If I disable the serial, everything is working fine.

How can I use both?

Thank's

=)

I am also looking to use sleep in my routine.
I don't know, but maybe you need to do a serial.stop before going to sleep.
Hopefully some of the experts will chime in.

Hello, I am also developing a project with that board and I am trying to "wake up" the BLE and the Serial Port. Any ideas?
