Hi Ralph,
This is great. I am using LimeSDR in my lab. So, I have few questions.
1- Could you please share your configuration files (epc.conf and enb.conf)
with us?
2- Where are located your configurations files? in the .config/ directory?
3-Where is located your user_db.csv? within the same directory where you
run the srsepc command or somewhere else?
Many Thanks,
