Devices aren't seeing each other #25

Open tmandry opened 8 years ago

tmandry commented 8 years ago

I haven't been able to discover anyone nearby, testing with 3 different devices (iPhone 5, 6, and 6 Plus) on the example app. Haven't changed anything.

There don't seem to be any interesting logs, except occasionally Received memory warning. On each device log I see this message repeated:

2015-10-05 13:28:37.027 DiscoveryExample[11294:1566532] Updating table view with users count : 0

but it only starts when I go home and reopen the app. In any case I can't get any of the devices to see the other.

I'm having the same problem, did you find a solution? iPhone5 and iPhone6S both with iOS 9.2.1.

I found my problem. The solution was described in issue #21, use the following code in Discovery.m: initWithUUID: self.shouldAdvertise = NO; self.shouldDiscover = NO;

switch (startOption) { case DIStartAdvertisingAndDetecting: self.shouldAdvertise = YES; self.shouldDiscover = YES; break; case DIStartAdvertisingOnly: self.shouldAdvertise = YES; break; case DIStartDetectingOnly: self.shouldDiscover = YES; break; case DIStartNone: default: break; }
