Re: Re: lost sms

Thanks Luca! Yes, my network does not use encryption, but I did not specify TMSI when using ccch_scan. How could I specify TMSI ? With a new parameter when using ccch_scan? And, what if I use lots of phones(e.g. 8 or more) to sniff per ARFCN? Will I capture all the message sent by myself?

If you use ccch_scan _and_ specify your ARFCN _and_ specify your TMSI _and_ your network does not use encryption, then you will probably be able to see your SMS in wireshark. Please note that the TMSI may be re-allocated by the network at any time. To make testing easier I suggest you to use a second Osmocom phone running the official mobile application/firmware and set the "stick" option in the configuration, so the ARFCN will not change.
