Hi Paul,

I'm fighting a similar problem while using the current development 
branch of OsmocomBB. Trying to connect to both OpenBSC and OpenBTS using 
the test SIM that's available in OsmocomBB.

I have a Motorola C123.

Is this feature supposed to be fully functional at the moment?
Before trying to associate, I switched the mobile to the 
network-select-mode: manual.
The latest behavior is that it's not possible to connect to OpenBSC with 
the following output from the "mobile" OsmocomBB app:

OsmocomBB# show cell 1
