I have a temporal solution for this.. i manage the duplicate SSID in b4a using arrays. If anyone want to know i can share the code.

westingenieria said:
Great library. Thank you for your work. Now i made a little modification (WPA+static IP) if someone has some interest i can upload the library...

I have a problem with scanning networks... i have duplicate SSID in my list :sign0148also in the log). I cant find the problem... Ill appreciate if someone can help me.

PD. sorry for my english, i know it sucks!

i tested the example project in this thread, but didn't work.
"no network found"
and when "refresh" still show up no network found.
i don't know what's the problem

Hi Vb1992,

there is a way to get an event when a new network is available ? I would get notice when a new Wifi is available without doing a time scheduled scan ...

Thanks
Fab

I get a divide by zero error using sample 1.2 with library 1.1 and 1.5. It fails on line 120 "Buffer = MyWiFi.GetWifiList" and log shows it gets my network data but dies when it sees my neighbors network.

This library seems to be the only one that has the functions I need but with this bug it will not work.

Please, who is interested - try my project, attached.

Hi vb1992 & NJ,

I have just tried using the sample apps(version 1.1 and 1.2) and also the APK with the library(1.5 BETA). I can get the list of all WiFi networks, but when i try to connect to one of them, I get the following error:

android.system.ErrNoException: recvfrom failed: ETIMEDOUT (Connection timed out).

Any pointers or things that I can try?

TIA,

Harish
