Stephen Siadak sws at arbor.netWhile I think I am pretty close to getting my ip.access nanoBTS to
communicate with my laptop running osmo-nitb I seem to be running into a
problem.
I am running openbsc-0.9.13 and using libosmocore-0.1.30
When I start osmo-nitb I see this error:
./osmo-nitb -T -c ./openbsc.cfg

I am using one of the stock nitb configuration files with no modifications.
openbsc.git/openbsc/doc/examples/osmo-nitb/nanobts/openbsc.cfg
My setup is a little odd. I did not do the original configuration for
the nanoBTS. I was hoping to just get stuff working with the current
configuration before I changed anything.
The nanoBTS comes up with an IP of 2.2.2.1 and expects a gateway of
2.2.2.2. So I simply configured the ip eth0 on my laptop to 2.2.2.2.
Then annoyingly the nanoBTS starts looking for 3.3.3.3. Now I start
getting a little hacky to try and move stuff along:
ip addr add 3.3.3.3/24 dev eth0
ip route add 3.3.3.3/32 via 2.2.2.2
I am able to use ipaccess-find:
./ipaccess-find eth0
# finally shows
# MAC Address='00:02:95:00:51:83' IP Address='2.2.2.1' Unit
ID='1801/0/0'

# Software Version='168a302_v142b13d0' Unit

# Serial Number='00106317'
I am also able to use ipaccess-config:
./ipaccess-config -u 1801/0/0 -o 2.2.2.2 -r 2.2.2.1

At this point I try to start osmo-nitb and receive the error I mentioned
earlier:

I think the bts type is set correct in the configuration file:
type nanobts
I am not sure what setting actually sets the frequency.
I am happy to provide more information and any help is appreciated.
Thanks in advance,
