Well, if you just want to enable the RF you can search for rf_lock inside the
network section. It will bring down the RF. If you want to have faster
development roundtrips you want to look at the bsc_proxy. It will be inbetween
the BTS and the bsc_hack. There is one issue to be fixed though.. on the
second BTS bringup OpenBSC still thinks the bts is down and you can not
allocate any channel...

Sorry, I am not so much into speculation. Please record a tcpdump, maybe
wireshark is even complaining about the message...

Yeah, the "blob" part in the row is meant to be a pre-encoded SMS, I don't
know if sending is enabled but as usual patches are welcome.
