I believe you have to make sure that "end-of-burst" is set and wait for an ACK from the USRP. This allows the FPGA buffers to clear, at which point you should be able to start RX. Someone please correct me if I'm wrong :)

The daugtherboard being used is the WBX. I have 2 antennas: One antenna (Rx) is connected to the Rx2 connector on the WBX board the other antenna (Tx) is connected to Tx/Rx connector on the WBX board. I'm not doing Rx and Tx at the same time (for now....) Tx is working fine. Rx is not because Tx is still sending data (last packet??). Rx and Tx are using close frequencies.... so the Tx is interfering with the Rx.... I tried after stopping the Tx, so send a bunch of packet with 0 data in them...no difference. For now the only solution I found is when a switch to Rx mode, I set the Tx frequency to a different value (ex: 800MHz instead of 200MHz). Is there a way to completely stop the Tx?
