BladeRF 2.0 2x RX

Post by bmagistro »

I was trying to setup receiving on two channels. I did find https://nuand.com/forums/viewtopic.php?t=5070 which helped me get the number of channels setup. For quick testing, I pointed the second output to a null sink so that the only change should have been enabling/adding a second channel. When I enable the second channel (same frequency and bandwidth), the rest of the flowgraph doesn't seem to produce any data. If I reduce the channel count back to a single channel, it produces the expected data. I'm not sure if there is an additional setting that I am missing. Adding a waterfall gui I am fairly certain I can see the signal of interest when it is transmitted.

BladeRF xA4 / BladeRF xA9
FPGA: v0.11.1
OS: Ubunutu 18.04
GnuRadio: 3.8.2.0 (via pybombs)
gr-osmosdr: master/v0.2.2 (via pybombs)

EDIT:
Relevant files are shared https://filebin.net/95iout5dwfwbcvg8 (expires in 1 week). I am now wondering if this has to do with https://nuand.com/libbladeRF-doc/v2.2.1 ... m_a_t.html
