Hi Paul
Removing that from the sib23 config, that error goes away. The attach
connection does not fully complete though - the tun interface never
seems to get created in linux. This is the current output:
sudo srsue

Failed to Attach
And running ifconfig, there is no additional tun interface shown. After
the 'fail to attach' the tx LED on the USRP goes out and the radio goes
to sleep. Amarisoft logs show that while the IMSI tries to register and
is assigned an IP, the registration does not complete. Currently looking
into this further - will update if I can find what the problem is!
Also noted an outdated parameter name in the ue.conf.example file in the
gw configuration section and have made a pull request.
Thanks
Kenny
