Hi,

I was able to reach this point (Limeutil update successful and S1-setup-response complete): Hopefully someone can assist me.

Thanks,

Hi Dave,
If You can share the soapySDR ver, Lime Suite ver and srsLTE ver its easier to someone smarter than me to help.
and also what You have changed in srslte “enb.conf”

24

theboel, thank you. I haven’t change any config of default srslte. the soapysdr version is 0.8.0, Lime suite version is 20.07
I can see my limesdr mini info with SoapySDRUtil -find command

Hi Link,

I do not have LimeSDR mini, my suggestion based from my experience with limeSDR USB.
I never use soapy 0.8. one of srsLTE development team suggest use less than 0.8 ver because different API.

26

Theboel, thank you For the suggestion, I will try older version.
