We're using Qt 4.8.2 on an embedded Linux device. We've always had Ethernet
(eth0) and we use QUdpSocket to send a multicast message on the network:
m_pUdpSocket = new QUdpSocket(this);
m_pUdpSocket->writeDatagram(json.toAscii(), m_cMulticastAddr,
m_cMulticastPort);
This works fine, but recently we've started testing with a Wifi interface as
well. What we've found is that this code only transmits the multicast on
Ethernet and ignores the Wifi. From the application we have to create a second
QUdpSocket and bind it to the IP address of the Wifi interface. I would have
expected Qt to transmit on all available network interfaces.
- Is this a known bug? If so, is it fixed in a later release?
- Is this working as intended?
Thanks,
Tom Isaacson
