SangHyuk, I'm really getting desparate. The fact that your application generates 400B over-the-air packets has *nothing* to do with the size of the sample packets going through Ethernet. Stop assuming that. > I expected one send() be represented one packet at wireshark. You should not expect that.

Hi, I counted number of sending packet in code and wireshark. I send 400Bytes packet, but wireshark packet be shown about 1500Bytes. While coded counter shows about 50,000 packets (data packet), wireshark captured 450,000 packets. I expected one send() be represented one packet at wireshark. W

While UDP gives no order guarantee, the USRP still sends them out in order. The uncertainty comes in cases where routing happens between the USRP and the host. Still, within a LAN you can expect with relative certainty, that packets will still arrive in order, as there is usually only one route fro
