Re: [Discuss-gnuradio] Re g : usrp2_card_burner_gui.py
Well I got the solution
Its some python version problem. With 2.7.2 its working fine. I have 2.6 in
the problematic systems.
So told by Josh I removed the " errors='ignore' " from usrp2_card_burner.py
from line 53
and it worked finally. :-D

This is not a gnuradio problem. Its a UHD bug that was introduced from a
language fix for the card burner. So I can fix it, please tell me:
What version of python are you running?
Does the app work if you remove "errors='ignore'"?

[Discuss-gnuradio] strange behavior when make gnuradio in build directory
Hi all,
I meet a strange behavior when building gnuradio (v3.5.3.X) on my
desktop with Fedora 16 these two days.
When I build in the directory build/:
rm -rf *
gr-cmake # my script which call cmake with some options enabled
make -j 8 && make test
The test 'qa_pmt' always fail. When run
./gruel/src/python/qa_pmt_test.sh, I can see the error message.
It is attached below for your reference.
However, when I build in some different directory, say build-test/,
build-another/, or build2/, and repeat the commands above, all tests
will pass.
I have cleaned the directories and tested many times, and qa_pmt always
fail under build/ but always pass under other build directories.
Occasionally I get compilation errors with make -j 8, I will then try
make with less parallel jobs. But it doesn't affect the phenomenon
above. I am not familiar with cmake now but I don't think the make test
result should vary with particular build directory. Maybe this indicates
some problems with the OS?
(I will also attach the script gr-cmake, although I do not think it is
relevant.)

[Discuss-gnuradio] Tweaking digital_bert_tx and digital_bert_rx
Hello everyone, Lately, I have been trying to tweak the way both digital_bert_tx and digital_bert_rx are working by introducing in the transmitter side my own generated random .dat file instead of transmitting an infinite vector of ones (default) while at the receiver side I consider the transmitted data known and I am making use of the error_rate block for evaluating the Bit Error Rate. However, the file source that I am using as a reference input in my error rate block at the receiver seems to introduce overflows after some time at the receiver as I am repeatedly giving as an input a predefined randomized sequence of bytes. Moreover, using a scope sink at the output of the error_rate block I get probability of error close to 1/2 either transmitting or not. Does anybody have an idea of what could be the problem in the above scenario or even better has tried something similar in the past? Thanks, George The experiment takes place in the latest revision of both gnuradio and UHD, Ubuntu 11.04-64bit in Intel core-i7 laptops. -- Sklivanitis Georgios Postgraduate Student Telecommunications Division Technical University of Crete ECE Dept.

[Discuss-gnuradio] How to implement a TDMA system
Hi everyone, I want to implement a TDD system with three USRP2 and an IBM server with three Ethernet cards. The scenario is one relay and two nodes exchange data through the relay, I want them to transmit data in their fixed time slot, it does not need to be too precise, about 100 milliseconds per slot is OK. The question is: 1. Can I achieve my goal with the current equipment? 2. I want to use the time-stamp in UHD to precise control the time to send and recv, but without external clock, does the UHD have to use the external clock to get the time? Thank you in advance! -- Best regards, Pan, Luyuan ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
