Multipeer Connectivity: getting an invitation accepted (using built-in browser VC)

Question

I\'m trying to follow the WWDC talk to learn about the MultipeerConnectivity framework. After many false starts, the browser(s) show the peers, and invitations get issued.

Answer 1

I was having the same issue and it turned out i was using the same session for both the browser and the advertiser. split up the sessions but make sure serviceType is the same and it'll work like a charm

- (void) setUpMultipeer{
    //  Setup Peer ID
    self.myPeerID = [[MCPeerID alloc] initWithDisplayName:[UIDevice currentDevice].name];

    //  Setup Sessions
    self.advertiseSession = [[MCSession alloc] initWithPeer:self.myPeerID];
    self.advertiseSession.delegate = self;

    self.browserSession = [[MCSession alloc] initWithPeer:self.myPeerID];
    self.browserSession.delegate = self;


    //  Setup BrowserVC
    self.browserVC = [[MCBrowserViewController alloc] initWithServiceType:@"SERVICE_TYPE" session:self.browserSession];
    self.browserVC.delegate = self;

    //  Setup Advertiser
    self.advertiser = [[MCAdvertiserAssistant alloc] initWithServiceType:@"SERVICE_TYPE" discoveryInfo:nil session:self.advertiseSession];
    [self.advertiser start];
}
