Hi,
I just got hold of a ip.access nanoBTS model 139U, but so far my
attemps at making it work with OpenBSC have been unsuccessful :(
It's a 'used' one so there are config already done most likely and I
don't know which.
What differs from
http://bs11-abis.gnumonks.org/trac/wiki/nanoBTS :
* It doesn't request an IP by DHCP
It seems to have IP/Netmask and GW hardcoded.
* When plugging it, it tries to do an ARP request for what I guess
his the GW address, and when it get a response, it tries to connect to
TCP port 3022 (yes, it's 3022 and not 3002) of yet another IP in
another subnet (which I guess is the configured Primarly OML IP)
* ipaccess-find does find it :

* ipaccess-config fails, the nanoBTS refuses incoming connections on
port tcp 3006
* Here's the result of a NMAP :

* I then tried to run ipaccess-config to port 3026 but it fails (just
waits a while thensays short read / BTS disappeared)
* I tried making openbsc listen on 3022 but with no real results :
