I tried to make an app to communicate between iOS devices and I found "Chatty", which is based on NSNetService (Bonjour) and it works on my devices. (iPad 3Gen, iPhone 4S and iPhone 5)

However, there's a problem, some devices cannot find each other if I use the "Internet Sharing" of Mac OSX to make Wifi hotspot, or connect to a b/g/n mixed 2.4GHz router, but it work perfectly if I use the hotspot of my iPhone 5.

Can you tell me why it cannot work in these routers? I guess that Bonjour is influenced by other routers in the room which I didn't connect, is that true?

  • I recommend a factory reset on your router, if possible. We had a similar problem and it was due to the router's internal settings and security. You can set up a password after, if you wish, that will not hurt things. – borrrden Apr 18 '13 at 07:41
  • Thanks, however it does not help so much, the devices can find each other now but cannot communicate... – Hiraku Apr 18 '13 at 13:15
