Hello,

I’m having a lot of trouble here while trying to make openBTS work with  
my USRP N210  
to play with GSMs.  
First of all, a little description of my setup:  
Software:  
openbts v5.0  
gnuradio  
UHD from git  
OS: ubuntu 14.04 LTS 64 Bit

My phones cannot find the network, I’m trying with a LG L80 and sony  
experia, whereas all indicator led in USRP N210 is on. And  
usrp\_uhd\_probe not trouble.

I would be glad if somebody had an idea where I could look next.

With best regards,  
agus
