Hi everyone, I'm trying to establish communication between two USRP2 using benchmark example. The command "./benchmark_tx.py -f 2.4G -r 500k" doesn't work: USRP2 can not correctly decode the packets received, all packets are 'false'. (PS:Same command works well on USRP1) After many times' tests, the following magic combination are able to show better results. --------- #./benchmark_tx.py -f 2.4G -r 500k -s 98 -i 14 -discontinuous #./benchmark_rx.py -f 2.4G -r 500k -d 14 --------- Test Result: Received packet rate: 98% Received OK packet rate: 97% I'm wondering why I could not receive 100% correct packets?
The test environment: Ubuntu 9.04, GNU Radio 3.2.1, the SD card is updated with latest version of firmware images (http://gnuradio.org/releases/usrp2-bin/trunk/).USRP2 is bought the end of 2008 with daughterboard XCVR2450. I would appreciate if somebody can tell me what is problem of my test.
