Hi:Kieran 1 I uploaded the Ethereal files .
2 I set ARP_QUEUEING to 1 ,in lwipopts.h 3 When i changed "p->payload = (void *)Test;"to"memcpy(p->payload, Test, sizeof (Test));",the udp content changed to "00000...",you can find it in the file. 4 I changed to PBUF_TRANSPORT,it is no use. 5 Your patience is impressive! thank you again! the_gadfly Kieran Mansley wrote: > > On Fri, 2009-07-03 at 05:41 -0700, the_gadfly wrote: >> Thank you Kieran: > > Also, as well as changing the way you get the data in the payload region > of the pbuf, you should also use PBUF_TRANSPORT rather than PBUF_RAW to > make sure there is space for the headers in the calls to pbuf_alloc(); > > Kieran > > > > _______________________________________________ > lwip-users mailing list > [email protected] > http://lists.nongnu.org/mailman/listinfo/lwip-users > > http://www.nabble.com/file/p24323559/you_can_open_them_by_Ethereal.rar you_can_open_them_by_Ethereal.rar -- View this message in context: http://www.nabble.com/how-to-send-udp-messages-circularly---tp24321123p24323559.html Sent from the lwip-users mailing list archive at Nabble.com. _______________________________________________ lwip-users mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/lwip-users
