FRDM-K64F Low Power Modes?

Has anybody been able to get the FRDM-K64F board to operate under "low power mode"? I am using the AT&T IoT Starter Kit which comes with the FRDM-K64F board and an Avent cellular shield. I need to reduce power consumption as lo as possible while it waits to for the next sensor reading ( 1 minute, 5 minutes etc.) and transmission of this data to AT&T Flow.

There are several examples out there but all seem to be for a different board model and not sure if some of this code applies to the K64F as well.

Any help would be greatly appreciated!

Thanks, Eduardo

Sleep/deepsleep functions work for the K64F as far as I am aware. However that just reduces the power consumption of the MCU. Those full boards aren't generally really optimized for low power consumption.

Thanks Erik. If I can at least get the K64 power reduced, I think that will be a good start and help with lowering power consumption to get more from each battery charge. Does anyone have sample code used on a FRDM-K64F?
