Hi,
I have the OpenBSC up and running with a nanobts at 900MHz. I would require some help with the following issues.
1) I'm able to view most of the air interface messages on wireshark but not able to view the gsm system information blocks. Is there any patches I should add on wireshark and is it possible to provide instructions on how to apply the patches ?
2) I'm able to see the rrlp request made to the mobile on wireshark. However I'm not see any rrlp response from the mobile on wireshark. I'm sure my mobile suppot ms-based rrlp request. Again, what are the patches to wireshark I should apply? Appreciate if details on how to apply the patches are provided.
3) I have copied out the gprs branch and am able to run the gprs OpenBSC codes without any problems. Just that at this stage, my mobile (i-phone 3Gs) does not seem to be able to do a gprs attach and have the OpenBSC allocate it a P-TMSI. Is there any thing I should do to get my i-phone 3Gs to do a gprs attach on the OpenBSC? (For my i-phone 3Gs, the settings is gsm mode only)
4) Also in the OpenBSC folder, there's this rrlp-ephemeris folder, if possible, would like to have further details on the purpose of the rrlp-ephemeris folder.
Appreciate any kind advise and help.
Thanks so much Ken

no, it always worked with the current wireshark svn version. no patches needed for proper RSL decoding. maybe you're using some old/release version of wireshark.

again, no patches needed. if your phone doesn't respond, it doesn't like the request or doesn't suppor RRLP.

the gprs branch is highly experimental, unmaintained and unsupported at this point. Don't expect anything to work at all. I'll get around improving that through the next weeks/months.
