I'm seeing a difference in behavior between gr-uhd and plain uhd c++ api:
Setup:
B210, 2 channels, 5MSPS, master_clock_rate 20MSPS, PPS sync
Receive only flowgraph
With gr-uhd, there is always a "OOD" when the flowgraph first starts
But, if I replicate the setup in a simple compiled program usin

Hello,
I'm looking to transmit a wideband signal from an X310 at 100 MSPS, so I'll
start by posing the very general question of what tips and optimizations do
I need to make to be able to do this reliably.
Here is what I already have set up (this is using a powerful server - 60
cores at 3.4GHz)
