Hello,
In regards to the WinNet750SR. If the Host sends a UDP broadcast packet, in certain situations the Wiz 750SR will send the correct response UDP packet, in other cases it won’t
The case that works:
Packet Source 192.168.0.99:54344 to Destination 255.255.255.255:52380
Note the response packet from the 750SR at IP addr 192.168.0.2
The case that does not work:
Packet Source 192.168.0.10:65312 to Destination 255.255.255.255:52380
If ip is 192.168.0.10, there is no reason not to respond.
Is 192.168.0.10 another PC?
192.168.0.99 If the packet is being captured by the PC, the packet transmitted by the WIZ750SR will not be visible. Since the packet transmitted by the configuration tool is a broadcast packet, it can be seen on 192.168.0.99 PC.
If this is not the case, it may be because 192.168.0.10 does not give a response to the ARP transmitted by WIZ750SR.
The 192.168.0.10 , the case that does not work, is a Sony Control panel that is acting as the host. The 192.168.0.99 ,the working case, is a a PC that is running a Sony app that is supposed to simulate the Sony control panel
When broadcasting from the Sony control panel (192.168.0.10) the PC app is not running, only Wave Shark to monitor the traffic
I believe you are correct in that the 192.168.0.10 does not give a response to the ARP transmitted by WIZ750SR.
Can you steer me some documentation on the expected ARP packet transmitted by the WIZ750SR, a waveShark screenshot or similar would be fine.
If indeed this is the case, is there any way to configure WIZ750SR to reply to this broadcast UDP packet from 192.168.0.10
