Hey again
Ok, got the UE attached. Digging through the nas.cc file I noted that it
only supports EPS only attaches. Changing our ePC to support EPS only
attaches, it connects and I can get online.
Just flagging this as a potential issue for when trying to attach srsUE
to commercial networks - it is rather unlikely that a commercial core
would support an EPS only attach. Probably worth adding to the
documentation!
Thanks
Kenny
