Description

When using the gr-osmosdr block with BladeRF 2.0 dual receive modes, the receiver misses every other buffer. The detailed experiment is shown here:
https://github.com/Abdob/FRS-Transceiver/blob/master/README_PART1.md

To fix the problem, the file bladerf_source_c.cc needs to be modified. The modified file is attached. The fix is also explained here:

Note that the first uploaded file (on 1/28/2022) was actually made for an earlier version of the code and is now not building. I've uploaded another file (on 1/29/2022) that does build but produces a warning at line 340. However, it should work fine. The purpose is only to demonstrate the problem.
