BladeRF Sink and BladeRF Source - Cannot Output Clock

[MaxenceCrvlh]

Hello, I am using the BladeRF blocks in Gnu Radio 3.10.1.1. I am using multiple bladeRF 2.0 Micro xA4.
These blocks allow a lot of things that are not possible with Osmocom or Soapy blocks, one of them is choosing to enable the output clock for synchronization.

However, when I modify the value of the boolean from clk_out: False to True in the block parameters, and click "apply" it does not save it and the clock_out remains disabled.

I am trying to go around that by simply modify the generated python file once the .grc ran but it does not provide a long term solution.

Do you have any idea on how to change that part in the source code of the blocks themselves ?

Thanks,
Best Maxence

Hi,
unluckily I can only confirm that problem still occurs with Gnu Radio Copmanion 3.10.1.1 (Python 3.10.12), bladeRF micro xA9 and newest gr-bladeRF downloaded from https://github.com/Nuand/gr-bladeRF

Found a way to fix this problem. Commited fix, but not sure if it will be accepted. When you download repository from https://github.com/Nuand/gr-bladeRF you need to change code in file /gr-bladeRF/grc/gen_bladerf_blocks.py

Find: '- id: out_clk'
and make sure it is set like that:

• id: out_clk
  label: 'Output clock'
  dtype: enum
  default: False
  options: ['False', 'True']
  option_labels: ['Disable', 'Enable']

  Find '+ ",in_clk=" + '${'$'}{in_clk}''
  and under it there should be:

  • ",out_clk=" + '${'$'}{out_clk}'

  Then just:
  cd gr-bladeRF
  mkdir build
  cd build
  cmake ..
  make -j4
  sudo make install

  And this worked for me :D
  Hope it also will help you
