Official bladeRF forum

I have a x115 that I am having a problem with tx with and without the transverter board. I replaced the transverter so the problem has to be either the x115 itself, the usb interface, or me.

This is the board's codes:

bladeRF> version

bladeRF-cli version: 1.3.1-git-ba561a4
libbladeRF version: 1.5.1-git-ba561a4

Firmware version: 1.9.0
FPGA version: 0.5.0

Whenever I try to tx I get a timeout error. Using various GNURadio scripts including bladeRF_frs.grc, I get something similar to this:

If I transmit using the cli with 20 seconds of samples at 1msps (below), I will see a signal for ~630 seconds and then it disappears (timeout).

xb 200 enable
xb 200 filter tx custom
xb 200 filter rx custom

set samplerate 1000000
set txvga1 -6
set txvga2 25
tx config file=/tmp/2400hz.sc16q11 format=bin
tx start

I am confused as to the problem. Bad hardware?

Hi,

I have the same problem on my laptop
running Kubuntu (latest version, 64bit).

As a cross-check I installed
the same OS within a virtual machine
on the same computer.
Within the virtual machine transmitting
and everything else works fine.

But I'm still unable to bring down this problem
within the native OS.
