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.
