LOST 3054!
What would this LOST 3054! say ? It does not sound good anyway, but at
this point I am not skilled enough to read OsmocomBB logs.
That's fine/normal.
OK, good. Sounds scary, though. I would prefer FIND message when
things go righth :).
...
PLMN selection in state 'A6 no SIM
inserted'
Can somebody explain me what the hell is happening here ?
No SIM inserted ;)
You have 3 options:
1. Check out sylvain's testing branch for a working on-phone SIM driver
2. Use the SAP interface to a PC/SC smartcard reader with SIM inserted.
3. If you want to use GSM test set instead of real network, use test sim
functionality of mobile
Hmm.. I was convinced that there was some kind of SIM card simulation
implemented in the software and that for basic connection no physical
SIM card was needed...
Hrm, for cell_log I don't think you need a SIM but when mobile starts it
tries to register with the network which requires a subscription.
So, as I understood, to have a cell attachment
and to have some
packets exchange I will need to pull Sylvain's branch, as I have no
network nor PC/SC SIM card reader...
Yes, if you want to register on a network, make/receive calls, etc.
No, no.. I can
not start with that - seems too advanced for a
beginning... Just a simple connection. The simplest stuff possible.
For
just finding cells and catching announcements on the beacon channel, you
may be better off starting with cell_log
Yes great. I'd like to start only with that. So I guess current master
is able to do this, I do not need SIM...
I prefer to try this for a gentle introduction.
It is more or less operational except for those two
caveats:
1. TX disabled by default so that you have to actively *do* something
yourself before you can transmit on the air, presumably making it your
own legal responsibility (whatever that may mean)
Yes I noticed this one. But as I
said, I have no intention to TX
anything. Just to receive some signals and to have packet appearing on
my host running Wireshark. So, that I can slowly start changing/adding
logs to layer1 and layer23 code and observe consequences in
educational purposes.
2. Current SIM driver is broken, not sure why sylvains is not merged in
master but I have heard reports that even his driver doesn't work for
some SIM's.
OK. Great informations. Helps a lot !
