Trying out the tunnel.py example, we are transmitting a ping request between two USRP2s. The receiving USRP should respond immediately with a ping reply what the outpout is also saying. At all, this ping reply is not send. We can bypass this by deploying a time.sleep(0.05) at the RX-USRP before sending the ping reply (txpath.send_pkt(payload)). Thus, the transmission is left behind for 50ms which is not very convenient.

Is it because the hardware components have to settle and the tx/rx switching takes some time? Or might there be some configuration settings? A colleague of mine is supposing something about different transmitting mode like streaming and sending just bursts?

Thanks a lot in advance, I really appreciate your help!
