Comprehensive User Directive Manual Needed

Hi All,

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

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

i. Start the osmocon program

ii. Start Mobile App

iii. Turn C155 on

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

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

Osmocon Output:
