Samsung Galaxy as a router wifi

[gianpaolof]

Hello!
I've been looking through the net but could not find an answer to my problem.
Hope someone can help me here.

1)I have Samsung Galaxy (2.2) configured as a Router WiFi to which I connect an embedded device. So far, no problem.
After that, I'd like to have the 2 guys (phone and device) talking over the just created WiFi link. So, on the Samsung I've installed a simple apk that does a HttpGet towards the device. HttpGet fails ("network is unreachable").
2)If I connect the Samsung and the device to an external WiFi access point, everything works.

So, my question: configuration 1) is feasible?

best regards
Gianpaolo

This is the code of the getRequest() where the exception is thrown:

}catch(Exception ex){

Log.d("getRequest", ex.getMessage());
}

Maybe, and I mean maybe, your phone cannot work as a hotspot and a client at the same time?

Hi Szadik,
I think you are right. In your opinion, is there a definitive test I can do to show my boss that this configuration won't ever work?

SOLVED: my fault: the ip address of the embedded device was out of range with respect to the address given by the mobile phone and so the could not talk.

thanks a lot
