Hi all,

This weekend I had my first try with a C123, and everything seemed to
work great from the start.
But suddenly when uploading l1test.bin to the phone, it seems to hang
after the first three ARFCN's found, like so:

Hello World from apps/l1test/main.c program code

LOST!ARFCN Top 10 Rx Level
ARFCN   7: -102 dBm
ARFCN  10: -103 dBm
ARFCN  14: -103 dBm

When I press any button of the phone it continues by showing the
remaining ARFCNs, but nothing else:

ARFCN  43: -103 dBm
ARFCN  85: -103 dBm
ARFCN  87: -103 dBm
ARFCN 105: -103 dBm
ARFCN 115: -103 dBm
ARFCN 123: -103 dBm
ARFCN  96: -104 dBm
Starting FCCH Recognition

key=12 released

I also noticed the dBm values,  all channels are barely above the
noise floor, right?

Does anybody have tips on how to get running again?
Thanks,

Hessel
