Osmocom Trx with OpenBTS

Hi Guys,

So I was trying to use my osmocom phone as a transceiver for openBTS.

I followed the procedures indicated in this link "
bb.osmocom.org/trac/wiki/Software/Transceiver" and was able to successfully
load trx.compalram.bin on the phone, connect openBTS to it and sync the
clock to the strongest cell around

I got the output attached from openBTS

For some reason however when I search for the network I am unable to find
it.

I can not figure out what exactly is going on here and I was wondering if
any one can help

One thing to point out is that I was never able to set the below value to
the suggested value as it was not in OpenBTSs configuration options. I am
not sure if this has been deprecated or replaced by any other options

GSM.CellSelection.Neighbors =           (set to empty string)


Any help would be appreciated
