I've been studying the OsmocomBB documentation, but cannot find any clear
mechanism for interfacing with Kraken. Can you give some guidelines, or is
there any article that I have missed?

Thanks for your prompt reply.
If I understand right, earlier the workflow used to be:
USRP -> GNURadio ->Airprobe (Parse) -> Kraken -> Airprobe (decode)
Now the workflow is:
MotorolaC1xx -> OsmocomBB -> Airprobe (Parse) -> Kraken -> Airprobe
(decode)
Osmocom can do everything that Airprobe does, so Airprobe is not needed
anymore.
Can you please confirm or correct.
I've read the Osmocom/Sysmocom documentation, but could not figure out
what is the best phone option on Sysmocom shop for my use:
Do I need the Motorola C1xx with filter rework?
Not necessarily. Filter removed helps you sniff the uplink communication
from a larger distance. Downlink is much more interesting for the
beginning, though.
Do I need C1xx with Calypso chipset?
All Osmocom-capable phones, incl. C1xx, are built around a Calpso chip.
Cheers,

It will be very helpful if you can suggest.
