In packet transmitter.vi I m attaching the IPv4 header of 160 bits instead of 32 bits header. And in packet transmitter.vi i changed the start location of data. I received the ERROR: Underflow: the tx buffer was emptied before new data was provided. consider reducing the IQ rate, increasing the Write rate, or increasing the number of samples per write.
Please give me some idea how to remove this. after reducing the IQ rate, or increasing the samples per symbol its not working correctly.
