USRP N210 Synchronization

Hello. I am using USRP N210 devices in my work. I have the necessity to synchronize three USRP N 210 devices in order to implement coherent receiving for these devices. I would like to know if it is possible to synchronize the USRPs by using the splitted into three 10MHz and splitted into three PPS

Re: Trouble using zmq in oot module blocks

You need to add the following to your CMake files. In the top level CMakeLists.txt: Add the line: find_package(Gnuradio COMPONENTS zeromq) after the line: find_package(Gnuradio "3.8" REQUIRED) In lib/CMakeLists.txt: Change the line: target_link_libraries(gnuradio-xxx gnuradio::gnuradio-run

Hello, I am trying to create a layout for a USRP E310 based direction finder in gnuradio. I need to read data from two inputs and give a command to switch the switch. And so several times. But I have no idea yet if this can be done in gnuradio. Can anyone give some ideas on this?

RE: Questions on Polyphase Clock Sync block

George, I would recommend that you start with the below referenced example symbol sync flowgraphs and parameter settings and tutorials first, get them up and running well, and then tweak the symbol sync block settings to your desired parameters/settings for your scenario: - .grc examples: You

Re: ZMQ Message Debug

Hi Jay, This does not directly address your ZMQ questions, but pertains to your software setup. Would being able to install ROS packages through conda be helpful?: https://medium.com/robostack/cross-platform-conda-packages-for-ros-fa1974fd1de3 You could pair that with the GNU Radio packages a

Ok, understood. I've used PMT before, just not this function. Adrian On March 9, 2021 2:46:29 PM UTC, Jacob Gilbert wrote: >What Jeff is proposing is a small change to the behavior of the cpp >pmt::is_dict() function, so not just Python API. It is exposed to >python as pmt.is_dict(). > >Jacob >

Re: RFC: Behavior of pmt.is_dict() in v3.8

PMT dict is a different kind of thing, so if you do not use PMT for message passing or tags, this won't affect you at all. Should have put that up front. Thanks for the reply! On Tue, Mar 9, 2021 at 3:25 AM Adrian Musceac wrote: > Is this strictly Python API? If yes, it would be very unusual to

Re: RFC: Behavior of pmt.is_dict() in v3.8

Is this strictly Python API? If yes, it would be very unusual to use this function in Python. I think most people would write type(x) is dict Or isinstance(x, dict) So I think you're safe to backport this change. Adrian On March 8, 2021 9:18:00 PM UTC, Jeff Long wrote: >Looking for comments o
