no device find

[Xin Yao]

Dear Powder Users,

I am trying some different settings using srslte-otalab profile. I create multiple experiments using my reservation. But one of the X310 shows that "no UHD Device find" when I run the "uhd_find_device" command. I tried to power cycle it but it is not working. How can I solve this problem? I only have a few hours left, thanks for your help. 

Here is my experiment link: https://www.powderwireless.net/status.php?uuid=80643ea8-408a-11ef-9f39-e4434b2381fc#

Best regards,

Xin Yao

I went to look, but it appears the experiment you sent the link for is
gone. Do you know which X310 device it was?

Hi Kirk,

Sorry, I tried to restart the experiment to fix it, but it still isn't working. It is X310-2.

Best wishes,

Xin Yao

This should be resolved now. The SFP+ transceiver module on the switch
side had gone bad.

Hi Kirk,

Thanks, now it is working. I have another question. Do you know why the enodeB configuration got stuck when I tried to establish two links using the opposite central frequencies for two separate experiments (for example, experiment 1: dl=3430, ul=3530 and experiment 2: dl=3530, ul=3430)?

Best wishes,

Xin Yao

That is unlikely to work well since the downlink for one cell will be
interfering with the uplink of the other, and vice versa. You would
need to use different ranges for each cell.
