Hi all, after loading L1 to RAM and starting mobile app, "show cell" is giving me :

OsmocomBB# show cell 1 arfcn |MCC |MNC |LAC |cell ID|forb.LA|prio |min-db |max-pwr|rx-lev -------+-------+-------+-------+-------+-------+-------+-------+-------+-------

and

OsmocomBB# network search 1 logs : <0002> gsm322.c:3099 (ms 1) Event 'EVENT_USER_RESEL' for automatic PLMN selection in state 'A6 no SIM inserted' <0002> gsm322.c:3106 Event unhandled at this state.

OK

I have inserted SIM in the phone, and I know that SIM controller driver is not functional on the master branch.

However, is there something that can be done even in this state to have some packet logging in Wireshark ?

Yes, the fact that you cannot subscribe to the network has nothing to do with the gsmtap stuff which happens at a lower level.

I.e. do we need SIM for any communication over Um. I guess not, and I want to start at this state, and observe some packets that are traversing the stack for educational reasons.

You guess correctly.

Did you try to capture the gsmtap packets already as I had described before? What happened?

Can somebody point me how this can be done (with current master and no SIM functional).

what valuye did you pass to mobile for the -i parameter?

eg: mobile -i 224.0.0.1

then just tcpdump -s0 host 224.0.0.1 -w my-gsmptap-capture-file.pcap
