wifi signal strength

[Yannick S.]

Hi all,

I want to get the wifi signal strength of all the wifi network around my
PDA. I have see that OpenNetCF.Net allows that. Is there another way to get
the signal strength programmatically ?

thx in advance.

Why not use OpenNetCF.Net?

OpenNETCF.Net does not work on all Pocket PCs :'(

Why do you need another way? The OpenNETCF stuff wraps the API, which is
the direct way. I suppose you could write your own C DLL that calls it, the
P/Invoke into it, but that seems convoluted.

The required APIs aren't available on all Pocket PCs. With older versions
it's driver dependent, so there's no "universal" way to do it.

Although OpenNETCF wraps up all the NDIS API required for 802.11 cards, it
never tested with all hardware available.

Different device require different "data extraction" behavior and some
drivers also returns wrong (but recoverable) value. OpenNETCF only provide
VERY basical access to these information. So you have to test the
application with different devices and customize the extraction logic.

So why not simply fix the OpenNETCF stuff rather than starting over? You're
going to save days of work at a minimum.

Although OpenNETCF wraps up all the NDIS API required for 802.11
cards,
We're not made of money. In fact, we have an incoming revenue stream of
exactly $0/annum. We have no funding, no donations and we certainly
don't make any money with the Smart Device Framework. All the hardware
we use is paid for *directly* out of our own pocket.

So write an abstract data extraction layer and fit it into the hard work
Paul and the team have already done so that you and others may benefit
from the added value it would provide.

We don't have the resources to test with a whole myriad of different
devices. See my earlier comment about our incoming revenue. If we had
the resources, we would have done it already.
