Unfortunately no. Because there is no interface to access these packets. Remember, they are coming over radio frequencies, i.e. are modulated bursts and are decoded in a black box called “3G module” until PCM voice or USB data is coming out of it. What you are trying is to inspect a data stream inside that black box and the designers of these modules have done everything to make access impossible for us. > > This would not prevent any danger but could be used for analysis of possible > attacks or to be sure everything was fine. Well, such devices exist - but are several kg of weight and big - and very very expensive. They are called GSM protocol tester. just my 2cts, Nikolaus _______________________________________________ Community mailing list [email protected] http://lists.goldelico.com/mailman/listinfo.cgi/community http://www.openphoenux.org
