[Discuss-gnuradio] USRP1 can't correctly receive packet from USRP2 using benchmark_tx/rx or benchmark_ofdm_tx/rx |

Hi,
I have currently set up a transmission between USRP1 and USRP2 with FLEX900.
And got the following results.
In gnuradio/gnuradio-example/python/digital/
Successful transmission (ok = True) when
Tx (USRP1) : ./benchmark_tx2.py -f 900M --tx-amplitude=0.4 -m dbpsk2
Rx (USRP2) : ./benchmark_rx2.py -f 900M -m dbpsk2 -e eth0
Fail (ok = False and lost lots of packets) when
Tx (USRP2) : ./benchmark_tx2.py -f 900M --tx-amplitude=0.4 -m dbpsk2 -e
eth0
Rx (USRP1) : ./benchmark_rx2.py -f 900M -m dbpsk2
In addition, if using the original modulation like dbpsk not dbpsk2, the
transmission also not work as expected.
also ref to the two discussions:
http://www.ruby-forum.com/topic/203035
http://www.ruby-forum.com/topic/202105
I successfully transmit packet from USRP1 to USRP2 with the following
parameter setting.
Tx (USRP1) : benchmark_ofdm_new_tx.py -f 900M --tx-amplitude=0.4 -i 128
Rx (USRP2) : benchmakr_ofdm_new_rx.py -f 900M -d 100
But the same problem as above, USRP1 can't receive correct packet from
USRP2.
Does anyone has any suggection about this problem, please let me known,
Thanks.
Sincerely,
Fisheep
