Hi Paz,
what exactly doesn't work in your application? I can see you're trying to
create a 10ms delay for Comm to get started, before calling send. I'm not
sure if you should stop the timer before restarting it for another one shot.
Another thing to try is moving the timer start in SendMsg.sendDone after
CommControl.stop(). That's what I had to do to get the timer working in
this app.

Harri

Hi Harri,
Ok, I know that the power management functionality is built into MicaZ
HPL layer, but I just don't know how to use it.
I have been studying the CountSleepRadio example, and trying to modify it
to be totally sure that I understand how it works. What I have done is
adding it a data read, it compiles but doesn't work.
Do you have any idea on what is happening?
I include the CountSleepRadio example modified.
Cheers,
Paz

Hi Paz,
you don't have to include anything from CountSleepRadio. The
functionality it uses is built into current MicaZ HPL layer.
CountSleepRadio is just an example of how you can achieve power
management (stopping certain modules). When your system is "idle enough",
power management kicks in by default.
The only "but" is, power management doesn't work in any of the
measurement applications (XSensor, XMESH) for MicaZ, if that's what you
need. If you write your own applications, you can get it working.

Hello,
I have a doubt about the use of the "HPLPowerManagement" library.
I've already installed the application called "ContSleepRadio", working
fine.
The Makefile has only these lines:
>>>>>
COMP ?= SleepRadio
COMPONENT ?= Count$(COMP)C
include ../Makerules
<<<<
Now, I developed my application based on how "ContSleepRadio" uses this
library, but it does not compile.
Does anybody know any other example of how to use this library?
PD.
I use MICAZ
Thanks in advance,
Paz
