QuestionReceive broadcast UDP Pin
jeron121-Sep-06 4:14

Hi everyone,

I have a scenario where I wish to send and receive broadcast UDP packets to and from an embedded piece of hardware. The embedded hardware listens for a certain broadcast UDP packet (on port 46051), and responds with a single broadcast UDP packet (to port 46050). The HW and PC are connected directly together. The embedded HW does not transmit anything else. I can transmit a broadcast UDP packet (as seen by Ethereal) and the HW sends its response usually within 375us (which can also be seen by Ethereal) but my app never receives the data. When I connect my PC to another PC running a microsoft UDP sample program (msocupd) which can send broadcast UPD packets, my app does get the data. I noticed that when the 2 PC's were linked together, all sorts of packets were being exchanged (ARP requests, etc..) whereas the embedded HW doesn't transmit anyting. Can what I wish to do be done using sockets?


Thanks in advance,
Jeron
