Klaus Darilion klaus.mailinglists at pernau.atHi! First I do not know if this is the proper mailing lists, as I am not a developer but a user. But I couldn't find a user list. So please advice if there is a better list. I started playing with Osmocom and my "brand new" C118 :-) and meanwhile I made my first open source GSM phone call. Following is my list of questions and suggestions I experienced so far: - Build System: since the "Use the system wide libosmocore for host applications" commit it is required that libosmocore is built separately. But the documentation is still confusing. Thus I think it would be good to: - remove the libosmocore subtree git from osmocom-bb git - remove this line of text from http://bb.osmocom.org/trac/wiki/libosmocore: "When you download and build OsmocomBB, then libosmocore is automatically part of the package, no special action is required." - osmocom: some wiki pages refer to an "osmocom" application. Is there an osmocom binary? (I think most times it is a typo for osmocon) - I use Wireshark to capture the GSMTAP packets of "monitor". How do I find out in the Wireshark trace if a message is sent from the MS or is received by the MS? - I want to study the high layer messages (e.g. not cell selection but call setup, registering to the network) but I am lost in the debug flags: DCS:DNB:DPLMN:DRR:DMM:DSIM:DCC:DMNCC:DSS:DLSMS:DPAG:DSUM. Which ones are needed in my case? Is there somewhere a description of the flags? - Some tools (e.g. cell_log) give 'SAP' log messages, e.g: Failed to connect to '/tmp/osmocom_sap'. Failed during sap_open(), no SIM reader I suspect this is for communcation with SIM cards. How it is supposed to work? - Is this 'SAP' stuff only needed/useful for softSIMs? - Which application should create the /tmp/osmocom_sap socket? (osmocon only creates /tmp/osmocom_l2 and /tmp/osmocom_loader) - Would it be possible to remove the SIM card from my C118 and put it in an external SIM reader, and then let "mobile" use the SIM card in the external reader instead? Thanks Klaus PS: I'm willing to improve the documentation in the wiki with your answers ;-)
