[Openlte-announcements] V00.18.01

[Ben W. <bwo...@gm...>]

All,

V00.18.01 is available.  This version added more MME encoding and decoding
to the LTE library, pulled in a patch from Ruben Merz to add USRP X300
support for LTE_fdd_dl_scan and LTE_fdd_enodeb, added to
enodeb_nat_script.sh, added delayed user deletion, ol extension to all
mesage queues, ability to send EMM information message, and QoS for default
data services to LTE_fdd_enodeb.

WARNINGS for LTE_fdd_enodeb:
1) I have been testing exclusively at 5MHz.  Other bandwidths should work,
but may have issues.
2) Not many improvements have been made to user plane data support in this
release and it is still quite unstable.  Crashes will be common.
3) In order to support user plane data, a script (enodeb_nat_script.sh) is
run at install time to setup NAT using iptables and LTE_fdd_enodeb creates
a TUN device (tun_openlte) at run time to send/receive IP packets.  This
configuration worked well for me, but I can't guarantee that it will work
on every installation.  Please provide feedback if you are having issues or
if you have better suggestions on how to configure this functionality.  In
order to view the IP traffic, it is best to open wireshark and capture
packets from tun_openlte.
4) I had some major USB issues as I was in the middle of testing this
version.  I don't think these issues are due to openLTE, but please provide
feedback if you experience USB issues while using LTE_fdd_dl_scan,
LTE_file_recorder, or LTE_fdd_enodeb.

Future releases will focus on stability of user plane data with
LTE_fdd_enodeb.

Any and all feedback is welcome.

Thanks,
Ben
