[srslte-users] No connection between srsenb and ue

[lilijobo1 lilijobo1]

Hello guys,

I'm trying to set up a connection between a commercial ue (galaxy s8) with a programmed sim card and srsenb with my limesdr. I can find the lte network with my phone but when trying to connect to it my phone rejects it. At the moment I try to establish the connection to the network I get the message concerning the RACH and the followed disconnection. You can see this in the output of the terminals below. Could anyone guess why I can't get a connection?

Greetings

Johannes
