Comprehensive User Directive Manual Needed

Hi All,

Currently I have the Osmocon running layer1.compalram.bin using Motorola
C155.

Mobile runs as ./mobile -i 127.0.0.1. I followed the normal procedure as
followed:

i. Start the osmocon program

ii. Start Mobile App

iii. Turn C155 on

iv. Start Wireshark (Direct Path Source : Git ) with the following
parameters:



Osmocon and Mobile keeps cycling in a loop searching for possible PLMN and
perhaps trying to find a suitable
cell to camp on. After power measure with an average level of -95dB, FCCH
RecognitionL1CTL_RESET_REQ kicks in.
The layer1 process keeps in this loop continuously. Likewise the Mobile app
with gsm322 message of channel
sync error. My guess is Layer1 couldn't found a suitable frequency to sync
with. And I wonder why?

I'll like to know if anyone has successfully run Mobile without SIM using
the Master copy. 

Please, I'll appreciate any hint on what to do from anyone
Thanks.
