[srslte-users] Not receiving RAR

[Samie Mostafavi]

Hi,

I am working on my Adrv SDR to get connected to an OAI enodeB with srsUE. I
developed some custom drivers so the SDR is able to send TX buffers on
time. My srsUE gets synced with enodeB and starts the RA transmission but I
done get any RA response from the base station even though it detects the
RAs. These are the logs from enodeB:

The ue log is also attached. I would appreciate if anyone can help.
