Hi,
when I have a WLAN-device working on my system, how can I get a list of all WLANs that are available for it?
Or is there some other documentation about WLAN access available somewhere?
I don’t know what you mean by WLAN. Do you mean what other QNX nodes are on the network? You can read /net like a directory.
Ahem…no, WLAN like “Wireless LAN” - that funny little thingy that you have in all modern Laptops now.
The whole situation is nothing less than a shame: QNX claims to support WLAN-hardware but there are no information available how to access and use them.
- Google finds nothing
- the search function on the QNX pages finds nothing
- code taken from Linux does not work
- here within the forum nobody knows how to access the WLAN device?
So what kind of WLAN-API do we have? Is it a top-secret, stealth programming interface? Or just hot air?

Well for better or worse, QNX the company and the last version 6.+ has been focused on the embedded market. They support a wide range of processors, and a wide range of hardware. But there are lots of holes when compared to the desktop market. A number of areas have been slow in coming. USB took a long time. It’s still problematic if you have anything esoteric. I find the support of OpenGL ES something of a joke. There’s one or two embedded board boards that have hardware acceleration.
The cause of this is simple. QNX is very directly market driven. When a big customer needs something, it appears. So the simple answer to your question is that no one has needed a nice desktop like solution, at least no one willing to pay for it. There is supposed to be a couple wireless lan chips supported, but what that means I don’t know.

Or something like the following. Note wpa_supplicant
must be running first and have a line like the following
in /etc/wpa_supplicant.conf (doc’d with wpa_supplicant
and wpa_cli).
-seanb
cat /etc/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant
wpa_cli
wpa_cli v0.6.4

That is not true in this case. According to their hardware database they DO support WLAN, so they must have a working WLAN interface.
Hm, both are command line tools where I would have to parse the output. Isn’t there a native WLAN support out of the system? I’d guess ther must be one after WLAN support is listed within the hardware compatibility list…
