power management

Hey,
I've been playing with kismet in combination with a bluetooth GPS and
GPSD. Unfortunately I'm finding that kismet stops working a minute or
two after the device blanks the screen. I assume that the device is
disabling either the bluetooth connection, or the wifi. Perhaps
because kismet is accessing the wifi chip directly and not via the
maemo api, it is being forced into sleep mode ?

Is there any way of disabling the power management, of a more fine
grained control of it ?

Cheers,
Gav

Hi,

There is a way to prevent screen blanking described in the libosso
documentation:
http://www.maemo.org/platform/docs/api/libosso/html/index.html
http://www.maemo.org/platform/docs/api/libosso/html/group__Devstate.html
#gbd82d7b0160e26cd15479f2685697322

This might help with the networking too, didn't try myself. As you see
this device is not aimed at applications that sucks power all the time.
If you have such application you will have to work around the rest of
the system trying to conserve the energy.

Br,

Hi,

You can find the parameters timeout_wlan, timeout_dun_cs and
timeout_dun_ps in /system/osso/connectivity via gconftool. These
parameters are accessible via the Connection manager > Tools >
Connectivity settings > Idle times and seems to be related with your
problem (but i haven't tried them enough to assure you that it's gonna
work)

Ok,
Thanks for those replies, I'll play around with them and see what I can achieve

Gavin,
I don't remember the details for connectivity power management, but my
advice is to not force the LCD on unless you have a real need for it: it
really sucks lots of power and connectivity should provide its means to
keep the radio on. If not, then it's a bug.

Try using ifconfig wlan0 power off as root on a terminal. I tried once
and It worked for me.
