Hi Martin, | ... The trick seems to be to | use the 10 seconds granted by iOS upon incoming data received | through the VOIP TCP socket: when the app is woken up by such a | signal, let it wait for about 9 seconds, send a response to the | server, and go to sleep, only to be awoken immediately by the | server's response coming in through the socket; then again wait for | 9 seconds etc. (the most elaborate description I found is here: | http://stackoverflow.com/a/7393083) Do you know about "SBUnsuspendLimit"? iOS 5 or later will kill your app if it is woken up more then 15 times in 300 seconds. So I would stick to TCP on iOS. ;) Sebastian.
