Dear Rachida, you don't seem to be very familiar with how mailing lists work: 1. Please use a meaningful subject line. We get a lot of emails – and I can't read all of them at the same time. GMail will most definitely complain when you try to send an email that has no subject line. Writing a goo

Re: Help- gr-lora OOT Module failed to install!

Just so you know, there’s a much more up to date, better documented and more thorough implementation of LORA in GNURadio. I wouldn’t mess with the one you’re installing now. Repo: https://github.com/tapparelj/gr-lora_sdr Paper: https://arxiv.org/pdf/2002.08208.pdf > On Oct 19, 2021, at 11:24

Problems using multiple C files in OOT Block

Hello GNURadio Community, With complex algorithms, there are times when one needs to add C files to an OOT module on top of those created by the gr_modtool to make the coding more modular and cleaner. I made a try with a trivial C++ adder function file, but could not get it to work. Below is a des

Hello everyone, I'm trying to transmit a lora signal and receive it using two USRP. But it didn't work. Here is my flowgraph. I hope you can help me. I'm not sure about the link between USRP source and USRP sink. Thank you TX_USRP.pdf Description: Adobe PDF document

Re: Adding uhd-style tags, to soapy driver?

The timestamp in gr-uhd is useful because a USRP can provide the exact start/restart time of a sample stream, based on a GPSDO. A system timestamp at the call to work() is not quite as useful. I'd suggest that a "timestamp first sample" block would do the same thing, and would be usable for sources

Re: Adding uhd-style tags, to soapy driver?

Hi Josh, @Josh Bailey: great work! Thanks for the patch :) Sadly, for some reason, `patch` and `git apply` only see the first hunk (i.e. the changes to block_impl.h and the three static const pmts), and I can't directly put your email through `git am` because HTML + MIME-multipart seems to be h

How to call an existing class? How to modify it?

Hello everyone！ I am now going to rewrite the "ofdm frame equalizer" module, but I found that the "ofdm_frame_equalizer_vcvc_impl.cc.h" source code refers to "ofdm_equalizer_base" and other files. I want to know if I create a new "ofdm frame equalizer" OOT module, I copy The content of ofdm_fra
