USRP X410で"what(): RfnocError: OpTimeout: Control operation timed out waiting for ACK"が発生する。

[shoheikke]

I am creating an application that connects a USRP X410 and a Ubuntu PC to send and receive IQ streams.
When I run the application, I get the following error:
terminate called after throwing an instance of 'uhd::op_timeout'
what(): RfnocError: OpTimeout: Control operation timed out waiting for ACK

For reference, I will list the UHD and FPGA versions.

GNU C++ version 13.2.0; Boost_108300; UHD_4.7.0.HEAD-0-ga5ed1872

MPM Version: 5.3
FPGA Version: 8.3
FPGA git hash: c37b318.clean

fpga=X4_200

I would like to know what is happening. How can I solve this?

I have the same problem…Could you solve it?

In my case, it was caused by connecting the USRP 1GbE to a different network. Changing the 1GbE to a local network solved the problem.
