Does the PM3 rdv4 have power-saving features?
I'm considering developing a standalone application that needs to run every once in a while and idles the rest of the time, on a PM3 with a BlueShark module. It needs to last at least 8 hours on a battery charge.
Is it possible to shut down parts of the board / send the CPU to sleep / have it wake up on BLE events... that sort of things?

No really. You might consider the idea of hooking up the pm3 to a usb battery that lasts eight hours as a quick fix.
Remember the pm3 consumes most when the rf fields are on.

Okay thanks. I'll leave it running idling, see how long it lasts doing nothing.
The external battery pack isn't really an option: I'd like to turn a PM3 + BlueShark into a wearable. It's a nice little platform: it already has everything I need onboard in a compact format. But maybe battery life will make the idea unworkable.
