I am trying to connect a cell I scanned with cell_serach and for some cell it works and for some cell it doesn't.
When looking in the ue.log, I found that even when it did decode the MIB successfully, it also fails.
Setup Details
Ubuntu 20.04
USRP B210 - with power adaptor, GPSDO and USB 3
UHD - linux; GNU C++ version 9.2.1 20200304; Boost_107100; UHD_3.15.0.0-2build5
CPU - Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz
Expected Behavior
Either to find the cell and try to connect to it or not find the cell.
Actual Behaviour
The srsUE searches for a cell and fails to connect.
Usually the output looks like:

I ran the srsUE with --rat.eutra.dl_earfcn 1282 --phy.force_N_id_2 2
THe config files are as in the examples (except using device_args = clock=gpsdo) , I tried to play with the phy category:
