Dear all, I'm using BladeRF hardware in my system. I want to use two devices on the same computer. The "*osmocom Source*" lets me choose several channels, I actually need to use 2 channels. However, I don't know how to set the parameter "Device Arguments". Could anyone help me with this? Thank yo

Newbie to gnuradio. After struggling for a couple weeks with build issues, I finally have a yocto-based build for an embedded x86_64 target. I'm trying to execute a flowgraph that I demonstrated successfully on Ubuntu 14. I copied the resulting .grc file from Ubuntu to the x86_64 target. It is

Excellent! Thanks for your reply Felix! As Thomas Rondeau pointed out, the sync problem would ideally be solved with the correlate and sync block, as 802.15.4 packets have a known preamble and SFD but there might be some glitches with it. However, Thomas also optimized Costas Loop to be quite eff

Hi I am not familiar with those solutions. Could you please give a little more detail? How can I use msg ports/ stream tags? Are they available in python flow-graph or do I have to look into C++ block programming? Where can I see rx_time, rx_rate and rx_freq tags ? Regards, Jorge On 5 February

Hi Thesis, first of all: be sure to actually copy and paste the code you're using; what you've pasted can't run, since python is case sensitive and start() and wait() are written in lower letters. I don't understand what you mean with "close the scope"; can you elaborate? Greetings, Marcus On 0

[Discuss-gnuradio] Flush samples of blocks when changing centrer frequency

2015-02-05 Thread Jorge Gallo
Hi, I have a python flowgraph with several blocks. One of them is a "filter.single_pole_iir_filter_ff" which does a moving average. The last block is a Sink to file block. I scan several bands, 10MHz each, in order to get the power of the signals in those bands. I use moving average to get an av
