Re: Import problem of OOT module

Hallo Marcus, I checked the PYTHONPATH just by starting python3 and typing import sys sys.path As far as I know new OOT modules are installed under /usr/local/lib/python3/dist-packages And running the python files means either starting the flowgraph in grc oder python3 test.py, where test.py is

Re: Import problem of OOT module

Hallo Karsten, are you sure the PYTHONPATH is also set for the python files you execute? How do you set the PYTHONPATH, and how do you run the python files? Best regards, Marcus On 07.07.21 22:28, Dr. Karsten Schmidt wrote: > Hallo > > I’m trying to port a hardware driver from an older gnuradi

Import problem of OOT module

Hallo I’m trying to port a hardware driver from an older gnuradio version to to gnuradio 3.8. According to the steps described in  https://wiki.gnuradio.org/index.php/Guided_Tutorial_GNU_Radio_in_C%2B%2B#Creating_our_OOT_module

Re: packet_loopback_hier OTA problem

500 kS/s is *really* low for the USRP B2xx. Can you try with 1MS/s? (The CPU load is very fine) Also, regarding your RX gain: have you verified with e.g. a time sink directly attached to the USRP Source that the amplitudes are as you expect them to be? Something with a magnitude value ranging u

htop: https://imgur.com/a/jgzo3Gk flowgraph: https://imgur.com/a/2XN4Z35 I included a picture of the topology just incase I've missed anything glaring with it, although I did not change much at all to the example.

Re: packet_loopback_hier OTA problem

Hi Jack, the background shows that there's regular underflows. This might be a bug, or your computer being overtasked. Could you run e.g. `htop` or `top` to check how loaded your CPUs are? Best regards, Marcus DISCLAIMER: Any attached Code is provided As Is. It has not been tested or validat

packet_loopback_hier OTA problem

When running the packet loopback example, from version 3.10, it works as expected without SDR involvement. However when using an SDR sink and source I have no luck with it working. I have tried using different configurations of sdrs, frequencies and gain values all known to be working on other topo
