Once the Tdd engine is initialized on the Pluto there appears to be no way to get anything but zeros out of the receive buffer.
Example case:
In the Phaser-Control-with-MATLAB repo, running fmcwDemo.m. Once the script gets past line 111 (i.e. bf_TDD.Enable=1) the Pluto will not return anything but a zero (either in the script or through IIO oscilloscope until it has been power cycled. The phaser device behaves normally when running the pluto and phaser from the pi.
