Sometimes notification are not delivered

[niks...@gmail.com]

Hello all,

Its been a frequent problem for sending notification. Notification which I send are not received many a times. One thing that came to my mind was payload size which I find in the following code and checked it is well below 256

                    $message = new ApnsPHP_Message($deviceToken);

                    $message->setBadge($badgeCount);

                    $message->setText($alertMesssage);

                    $message->setSound($soundFileName);

                    $message->setCustomProperty("custom", json_encode($customMessage));

                    $push->add($message);

                    Logger::getRootLogger()->info("Payload Length= ". strlen($message->__toString()));

I am using it for Chat functionality, any pointers why is it not received many a times. Is it because of expiry is not set, if yes then how can it help?

Thanks.
