LimeSDR Errors

General Discussion

HI all,

Just received my LimeSDR and it is giving me the errors below. Can you guys confirm that the board is a DOA?

Please advise urgently

Hi @ronaldjeden,

Do you have something connected to RF inputs/outputs?

3

HI, for some reason I could not add comments so I have created a new account ronaldjeden2.

I bought the one with the antennas included. Tried them on different places but no joy.

Any other ideas? Is it a DOA?

4

Hi @ronaldjeden2,

Disconnect antennas ant try tests again, please.

5

Hi,

I did but no joy. With and also without. Same errors.

6

I did all of these things:

Tried VM Ubuntu, Windows 10, even a bare-metal with Ubuntu, USB2 and USB3 ports, change the antennas removed antenna’s changed firmware…

My vendor (Antratek) says they can only assist me if I got a valid RMA.

Hi guys Any update?

Can I return the device to my vendor?

Hi @ronaldjeden2,

Arrange RMA, please.
