Hi Bob, Your guess is correct, I found the error from Transmitter side. Now the synchronization is working fine. PN From: Robert McGwier [mailto:rwmcgw...@gmail.com] Sent: Thursday, December 15, 2011 8:53 PM To: Phone Naing MYINT Cc: discuss-gnuradio@gnu.org; usrp-us...@lists.ettus.com

[Discuss-gnuradio] SpecEst toolbox install issue

2011-12-16 Thread Marius
Hi! I have a small issue with the SpecEst toolbox install from cgran: https://www.cgran.org/wiki/SpecEst#HowToInstall I followed that Howto and the Readme. It compiled just fine on my Ubuntu 11.04, x64, v3.4.0-101-g7e2b45b8 sudo specest_gui.py linux; GNU C++ version 4.5.2; Boost_104200;

[Discuss-gnuradio] trying to create a simple packet analyzer in gnuradio

Hello, I'm trying to make a packet analyzer with gnuradio which will translate 802.15.4 messages for me. I already have a gnuradio block that would pass my a raw data of the message from that start of frame. Right now the messages are saved into a text file by connecting this block to a file

You’ll have to somehow convert and decode the raw samples into data and dump them as perhaps a PCAP file that can be analyzed in Wireshark. More general question – would it make sense for GNU Radio to have decoders than can dump to PCAP files? I noticed there are already TCP and UDP sinks, for

My end goal is to be able to re-transmitting the message to other 802.15.4 devices so I cannot dump it into a file. The decoder would be a simple one. Translation can easily be done by hand or even looking at the raw date itself (source, destination, short message.) Let's say if I have a block
