Re: [Discuss-gnuradio] problem running uhd_fft.py
Hi, Just to be clear and to complete the previous answers. It happens to me the same problem, i.e., the fft GUI is blocked (shadowed in grey color and not responsive). In my case, the problem occurs when pressing the "Peak Hold value" when using a Q6600 @ 2.40GHz with 4 GB RAM and NVIDIA GeForce 7300 SE/7200 GS. I checked it with UN210 and USRP1. Also, under a slower computer (core duo and 2 gb ram) the problem is increased. However, in both cases the CPU use is not at 100 %. If i execute this command line the problem seems to dissapear (checked in the faster computer and with XCRV daughterboard). uhd_fft.py -s 1M --fft-rate 15 -f 2.4123G --averaging Hope it helps, PS: i have installed the latest UHD version from the master branch. --M ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
Re: [Discuss-gnuradio] RX->TX Switching delay on XCVR2400?
I found something on the mailinglist that there might also be SEND_MODE_ONE_PACKET function beside the SEND_MODE_FULL_BUFF but actually it affects nothing as I replace it in the gr_uhd_usrp_sink.cc (after recompling etc.). In another thread it was mentioned that the transmitting buffer is not transmitted until it is full which is being done until the timeout time is elapsed. Does anybody have an idea how the waiting time could be skipped or this ONE_PACKET mode could be set up correctly? ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

You can just use "dir(gr)", or something like: for g in dir(gr): print g OR: print "\n".join([g for g in dir(gr)]) Both of these will print all available objects in gr, one per line. Also, you can use iPython as a command-line Python interpreter shell. In iPython, typing "dir(gr)" will print the objects as a column, too.

Imagine an application that is always receiving. When you transmit, the receiver is temporarily unavailable.

@Philip Balister the steps are 1. compiling wxGTk from source. 2. compiling wxPython from source. Then compile the gnuradio ,, These the main steps i went through ,If you want details tell me.

[Discuss-gnuradio] not getting timestamps from UHD received stream tags
I am trying to read incoming RX timestamps from the UHD sample stream. I'd like to calculate the approximate time a preamble is received in the OFDM code. The issue is that, despite getting incoming frames and preambles, I do not seem to be getting timestamp values. I use get_tags_in_range() on "rx_time": https://github.com/gnychis/grforwarder/blob/8f8c4e6cf79a2d635a0eb3bcad9b5ab325f1e373/gr-digital/lib/digital_ofdm_sampler.cc#L78 However, the size of the rx_time tags is consistently zero: https://github.com/gnychis/grforwarder/blob/8f8c4e6cf79a2d635a0eb3bcad9b5ab325f1e373/gr-digital/lib/digital_ofdm_sampler.cc#L99 The output of the OFDM receiver code: ok: True pktno: 637 n_rcvd: 18 n_right: 17 got a preamble, size of time_tags: 0 ok: True pktno: 638 n_rcvd: 19 n_right: 18 got a preamble, size of time_tags: 0 ok: True pktno: 639 n_rcvd: 20 n_right: 19 got a preamble, size of time_tags: 0 ... Is there something I am missing to enable the RX timestamp on the incoming samples, or am I not properly reading the stream tag? My branch came from the GR master 4 days ago (309ca769af).

Bingo, didn't realize they were only incoming at those points in time. Problem solved, thanks Josh!
