Applet not showing up after 9000 INSTALL for install
by Sabyrzhan Tasbolatov 04 Feb '22

04 Feb '22

Hello, I need help to understand my problem installing a simple HelloWorld applet on USIM card. There is already a USIM applet (AID: a0000000871002ffXXffXX89) running there, so perhaps that's the issue. 1. Should I remove it? Here is my code to INSTALL (for load), LOAD, INSTALL (for install): https://gist.github.com/Novitoll/2d8146b85f4384eb4dd039eb8116d1ed 2. All of them returns 9000, which is OK, I'm using a simple CardReader, but when I insert the SIM to a phone, no applet comes up. Initially, I thought that the AID for instance is the reason. So when I do https://gist.github.com/Novitoll/2d8146b85f4384eb4dd039eb8116d1ed#file-appl… ... module_aid="d07002CA44900101", app_aid="d07002CA44900101" I'm getting 6A88 (Referenced data not found). I changed it to A0000000871002FFffFFff8900000101 A000000087 - RID for 3GPP 1002 - USIM FFff - country code FFff - card issuer code 89 - Telecom 00000101 - App version? Havent figured out this yet the answer is 9000. But no app pops up on the phone once I insert SIM card back. 3. Also I'm checking if any load file actually ends up by taking some non-volatile space in SIM -- no difference. 4. After Install for install, there is nothing to be done, rght? Like updating EF_DIR is not required, where USIM is the only applet. Could you please assist? My twitter is twitter.com/novitoll Thanks, -- Sabr

INSTALL for install APDU failing
by Sabyrzhan Tasbolatov 21 Jan '22

21 Jan '22

Hello, Sorry, for the late reply. (replying again in new thread as prev mails failed). Quoted prev mails in quotes below. >> Which is "your test sim". Can you share the make and model? It's a sysmoUSIM-SJS1, I believe. I'm receiving 9000 for INSTALL for load, and for consequent LOAD commands 9000 as well. Only for the last INSTALL for install, I'm getting 6A88 (reference data not found). I think, the issue is in AIDs. I'm trying to figure out if I should use arbitrary bytes for AID or construct AID (which includes RID + RIX) the same way as existing Load Files, Applets' AID are on the SIM card? I'm using d07002CA44 from this https://github.com/mrlnc/HelloSTK2, I believe that should be reason for the 6A88 error code. Could you please assist?

Adding an ADF to SysmoISIM-SJA2
by bryan coxwell 17 Jan '22

17 Jan '22

Hello all, I'm looking for some guidance on adding an ADF which I will then be able to select by AID to a SysmoISIM-SJA2. Primarily I'm curious if there's any reason this WOULDN'T be doable before I continue down the rabbit hole of figuring it out. What I've tried so far is: 1) Pushing the applet to the SIM using shadysim_isim.py. It loads fine, and when I enable SIM toolkit it appears properly on my Android device. When I try to SELECT the AID however I get an error saying the AID doesn't exist. 2) I figure the above error is because EF.DIR doesn't include the AID, so I update the first empty record in EF.DIR to include the AID of my applet. When I try to SELECT the AID now I get the same error however. I'm not sure how to proceed but I figure now is a good time to see if it is in fact possible before spinning my wheels further. If anyone can point me in the right direction or even just a yes/no about whether it can be done that would be greatly appreciated. Best, Bryan

osmo-msc codecs
by Neels Hofmeyr 13 Jan '22

13 Jan '22

Hi all, I'd like to draw attention again to the state of codecs handling in OsmoMSC master. The reason being that the recent IuUP changes create conflicts with the neels/mncc_codecs3 branch. I fear that we are currently doing the same thing that we discourage everyone else from doing: keeping an important branch on the side and not upstreaming it. There is recurrent overhead on rebasing the branch. Facts about OsmoMSC: master neels/codecs_mncc* heeds MS Bearer Cap from ComplL3 NO YES logically combines codec constraints NO YES communicates available codecs to/via SIP NO YES worked at last congress NO YES has the last IuUP patches YES NO I think the reasoning for completing that codecs work and merging the branch is compelling. Can we somehow achieve that before OsmoMSC diverges further? I could start maybe by holding a talk on it in an OsmoDevCall? That way I've read all of the code again and can explain what the patch does why, to ease review. Or maybe spend that time on merging the code instead? Or both? :) ~N

Refreshing/Resetting UICC (SysmoISIM-SJA2)
by bryan coxwell 06 Jan '22

06 Jan '22

Hi all, I have a SysmoISIM-SJA2 which I believe doesn't have a CAT application and doesn't support the SUSPEND APDU (per the manual). Given that, is there any way to reset/refresh the card through APDU commands (or through any other means)? Would something along the lines of deactivating and then reactivating the USIM application work? Thanks, Bryan

lists.osmocom.org migrated to mailman3
by Harald Welte 03 Jan '22

03 Jan '22

Dear Osmocom community, today our mailing list server lists.osmocom.org has finally been migrated from mailman2-on-freebsd to mailman3-on-linux. This also included a variety of changes to DNS. I'll spare you the details, but everything _should_ be up and running now. * The List-Id headers should not have changed. * all list subscriptions + user accounts have been converted. * old 'static html' archives are still available (read only) at URLs like https://lists.osmocom.org/pipermail/baseband-devel/ * old List URLs like https://lists.osmocom.org/mailman/listinfo/baseband-devel are redirected to their respective modern counterparts In case you notice any mailing list related problem, please don't hesitate to contact me. Happy hacking, Harald -- - Harald Welte <laforge(a)osmocom.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

those harmonics) must be above: -30 dBm @ 30 kHz span above 1 GHz -36 dBm @ 30 kHz span below 1 GHz In case of UmTRX without an amplifier it's enough to use a ceramic or SAW duplexer to bring harmonics below those levels. For those buying UmTRX's as a lab package of universal UmDESKs, we offer to buy an external ceramic duplexers. These improves coverage and solves the out of band noise issues. For those buying band-specific UmDESK's, we use SAW duplexers, which are even more efficient in reducing out of band noise. >> A calibrated USRP N200 running osmo-trx passes RF spectrum and >> modulation accuracy requirements of 3GPP 05.05 by very large margins >> and is competitive with commercial GSM equipment in this regard.

You're obviously more proficient in European norms. Could you point me to a link where we could find these differences between the ETSI published GSM Standard and European harmonized norms?
