How to deal with “Transmit unsuccessfully: Could not execute UHD driver command in 'sendData_c': tx send error: sequence error”

When I want to send data from USRP X310, it reminds me an error:"Transmit unsuccessfully: Could not execute UHD driver command in 'sendData_c': tx send error: sequence error".

I can use USRP to send data, but I can only send around 3M. If it exceeds the limit, the error message will appear.How can I continue to send data? Expect an answer!

Hello @Yummy,

I understand you're experiencing issues with the USRP, and I suspect you might be using a RealTek Ethernet chip.

I faced a similar performance issue, which turned out to be due to hardware incompatibility, specifically the Ethernet chip used for the USRP connection.

Switching from a RealTek Ethernet chip to an Intel Ethernet chip resolved the issue for me.

Refer to the following MathWorks documentation for more details:

Hello, I'm also having the same issue with the error message as follows:

Transmit unsuccessfully: Could not execute UHD driver command in 'sendData_c': tx send error: sequence error

I tried using the ‘release(radio)’ command but found that it didn't solve the problem。

Have you solved the problem and is there any good way to do it？
