Hi,
I'm working on LowPowerListening interface to manage Radio Power. I've read the
tutorial about it but it does not explain how to tune that interface. I would
like to ask if someone could advice me a link to get more detailed information
about that interface and, in particular, how to define

Boomerang allows you to change the duty cycle via the lowpower parameter of

I think "beacons whenever a node wakes up from sleep" covers that :-)
But regardless, either you are sending additional messages to keep tight

With LPL you can do a simple calculation to calculate
a worst case packet delivery time.If sleep interval is

delay grows significantly. This explains the huge

Hi Antonio,
Gerat to hear that it works. The driver can lock up if it does not
receive the right interrupts. Branoislav Kusy has some fix to make it
more resilient (in case for some reason an interrupt is missing), but
those interrupts should be received on an undisturbed platform.
