[Discuss-gnuradio] uhd digital-bert script !
Hello everyone I am working on USRPN200 with RFX2400. I am trying to make digital-bert scripts to work for uhd devices. I have modified them a bit but i am getting some errors which am unable to debug. If anyone can help me out. Attached are my benchmark_tx and transmit_path scripts. while running the script, it shows me : aravind@COE-CW85V91:~/gnuradio/gnuradio-examples/python/digital-bert$ ./uhd_benchmark_tx.py -f 2500M -g 16 linux; GNU C++ version 4.4.5; Boost_104200; UHD_003.001.002-5239879 gr_fir_ccf: using SSE Modulation: 250k bits/sec TX IF rate: 500k samples/sec USRP interpolation: 256 DAC amplitude: 2000 -- Opening a USRP2/N-Series device... -- Current recv frame size: 1472 bytes -- Current send frame size: 1472 bytes -- mboard0 is MIMO master UHD Warning: Unable to set the thread priority.

Re: [Discuss-gnuradio] uhd digital-bert script !
I have made that change.

Aborted Some part of the block chain setup by transmit_path.py is producing floating-point values that cannot be easily scaled into the range required by the (I'm assuming) UHD sink block.
