Low Power Node Support in Nordic BLE mesh

[Charile]

I'd like to use the nrf52832 as a mesh switch with battery powered. But I didn't find any sample code for the Low power feature in current mesh SDK v0.10.1. Does it support this feature now?

And does the light node support the friend feature?

The nRF52 chip has basically three modes of MCU core when it comes to power: POWER ON, POWER ON SLEEP and POWER OFF. Now all Nordic example FWs are using POWER ON SLEEP whenever chip has nothing to process (only peripheral blocks do what they are programmed for through the registers but nothing needs to be computed - e.g. RTC timer is running etc.) and system just waits for interrupt/event. Now that's pretty much all you can get for operation when you need to have any HW peripheral running! POWER OFF is useful only if you will get wake-up by external signal such as GPIO pulse (button) or NFC field (if you have it implemented). So this is not really useful for mesh node.

Conclusion: all the examples supplied by Nordic should already consume as few power as possible by the HW platform.

Oh sorry, I misunderstood the question as general low power capabilities of the platform not as feature of BT SIG mesh! I guess clarifying the question helps;) I hope someone will reply soon;)
