Hi Kyle, Sorry for the long delay. In looking at the 30001 log (debug_output3.txt), it looks like this is only a portion of the output. I would recommend starting it before you run the "start" command from the 30000 control interface. From what I can see in the log, it appears that your UE is attempting to do an RRC reestablishment procedure. Can you try hard power cycling your UE and running again?

Code exists currently that supports packing/unpacking UE information request but not for UE information response. However, this is not currently used in the eNodeB.
