[Discuss-gnuradio] USRP Lan not detected

2013-09-08 Thread Medhat Hamdy
Dear all,     I am using USRP N210 with a Lenovo Thinkpad labtop. When I connect ethernet wire nothing happens (the leds on both the lab and the USRP do not flash). And also the network gives me the message "Wired Network Disconnected - you are now offline". Can anyone help me.   Medhat Ham

[Discuss-gnuradio] TDOA estimation with USRP and GPSDO

Hi all, I've been working with Cheng Chi (http://gnuradio.4.n7.nabble.com/How-good-can-USRPs-with-internal-GPSDOs-being-synchronized-td43502.html) on a project where we try to estimate the TDOA (Time-difference of arrival) of a signal using USRP-N210 equipped with a GPSDO board. The setting

2013-09-08 Thread john
Just wondering if there is anyone here who would be willing to have a go at porting the kalibrate tool for use with the hackrf, I think this would be a great tool to have but my programming skills are not good enough to complete this myself. ___

Hi Fokko, you have a misconception of what flowgraphs are. You call connect twice, connecting all the blocks twice; this can't be done, since every block only has one set of input ports. Please consider flowgraphs as mathematical digraphs: Just a set of vertices (blocks) and directed edges; if

Hello Marcus, I am sorry for the scare information. Please let me elaborate. The most recent version is pushed in my fork of the repository of gr-ais: https://github.com/Fokko/gr-ais/blob/master/apps/ais_rx.py I have digged in the generated python swig code, but the type of the osmosdr_source_c_

Hi Fokko, The information you're offering is a little sparse. Do you have the source code (at leas ais_rx.py in your current version) somewhere? On 09/08/2013 09:25 PM, Driesprong, Fokko wrote: He guys, I have managed to fix all the swig error's, but now I have some issue's with python. Mayb

He guys, I have managed to fix all the swig error's, but now I have some issue's with python. Maybe you guys have run into it earlier? All the SWIG objects and Python classes are available. But something might have changed in the connect method of the top_block. Traceback (most recent call last)

Hi Manu, Am I supposed to put ldpc.h in inlclude/ldpc/ and ldpc.cc in lib/? Or should I put both of them inside lib/ ? Which section of CMakeLists.txt am I supposed to modify? Yes, that would be the correct structure. Just add ldpc.cc to lib/CMakeLists.txt: It

Hi Manu! Suppose I don't know the block size before hand, and I want to pass a parameter "x" to toe constructor such that block size can be obtained from x using certain computation (that will be defined inside the constructor). Can I do this? If so how? Yes, that's possible *inside the cons
