[Discuss-gnuradio] problem with benchmark_tx.py with "--discontinuous"

[Sahoo, Anirudha]

Hi,

  When I run benchmark_tx.py with “—discontinuous” flag ON, I notice

the following problem:

 

   When the transmitter goes to sleep (for 1 sec), the receiver TIMEOUT (which is fine).

But then when the txmitter wakes up and sends the next 5 packets, the receiver consistently does not

receive the first packet (of this set of 5 packets). Occasionally, I see the rcvr does not

get the first two packets.

   So, I think there is some problem when packets are sent after a period of “lull”

which leads to very first packet (after a TIMEOUT) being lost.

  

   Can anyone think of what could be wrong with the ofdm implementation which may

lead to this problem?

 

   I am running gnuradio 3.6.2 on USRP N210.

 

 

thanks and regards
