Hi list. According to multiple sources, UDP broadcast is supported on WinPhone 8+ (e.g. look here <http://stackoverflow.com/questions/23504957/windows-phone-8-1-doesnt-send-udp-broadcast> , here <http://metronuggets.com/2013/03/18/how-to-send-and-receive-a-udp-broadcast-in-windows-phone-8-and-win8/> or here <http://01siddharth.blogspot.it/2014/08/send-and-receive-udp-broadcast-in.html>) but it seems that the feature in not supported in Qt since CanBroadcast flag is set to false in QNetworkInterface (or am I misinterpreting?) The test code I've used is as simple as the following:
udpSocket->bind(BROADCAST_PORT); udpSocket->writeDatagram(data, length, a.broadcast(), BROADCAST_PORT); A 4-bytes message is sent on a network where our target device is connected. The sent message is correctly received by the target BUT the answer we receive back is plain wrong. At least, the length of the messages match the expected lengths: \0x00cdcdcd // original message sent by my code - 4 bytes \0x00cdcdcdcdcdcdcdcdcdcdcdcdcdcd // answer from the target device - 15 bytes The very same code works fine on other platforms. Any idea or suggestion? Thanks in advance, F.
