I want to get some uniqe information from access points such as mac address (bssid). I try this code, but it is only works when I connect a network..
- (id)fetchSSIDInfo
{
NSArray *ifs = (id)CNCopySupportedInterfaces();
NSLog(@"%s: Supported interfaces: %@", __func__, ifs);
id info = nil;
for (NSString *ifnam in ifs) {
info = (id)CNCopyCurrentNetworkInfo((CFStringRef)ifnam);
NSLog(@"%s: %@ => %@", __func__, ifnam, info);
if (info && [info count]) {
break;
}
[info release];
}
[ifs release];
return [info autorelease];
}
How can I get bssid from access points around me even if I am not connected, is it possible?
