Hello! I tried searching the mailing list to see if anyone else has had this issue, but I didn't find anything relevant. Explanation: I am trying to install my java applets to an older sysmoISIM-SJA2 card with the "SELECTABLE" and "DEFAULT" privilges/flags. The reason being that I need my applets to auto select itself rather than manual interaction through the SIM Toolkit menu. Currently, I am using the shadysim-isim tool to load my applets, however, there is no option to make applets defaultSelect. And, it doesn't look like pySim supports this currently either. GlobalProtectPro (gp.jar) does have support for these cmds, but it looks like they need addtional parameters specific to the SJA2 when installing. Does anyone know what the exact parameters needed are? Someone else noted this issue under the GlobalProtectPro repo - but I'm not really knowledgeable enough to understand what was said. Link to the issue: https://github.com/martinpaljak/GlobalPlatformPro/issues/293 Link to their solution: https://github.com/martinpaljak/GlobalPlatformPro/issues/293#issuecomment-1… Thanks!

Dual SIM client support

by Sohail Arshad

Hello, I have a functioning setup of remsim as follow: * An x86 server that hosts a sysmoOCTSIM board. This server runs the bank daemon and also the remsim server. * An ARM64 client that hosts a SIMtrace2 board, and a 5G modem with two SIM inputs to support dual SIM single standby (DSSS). The SIMtrace2 connects to SIM slot 0 on the 5G modem via a flexi. * I use the remsim-apitool to create the slot map and assign SIMs to the client using the server IP, bank ID and client ID. Client slot is always 0. I’d like to allocate two SIMs in the bank to this one client using only one ATSAM4S microcontroller to utilise the DSSS function of the modem e.g. SIM slot 1 in the bank is mapped to SIM slot 0 on the 5G modem for client ID 1. SIM slot 2 in the bank is mapped to SIM slot 1 on the same 5G modem for client ID 1. Is this possible with the current implementation of remsim? I cannot find any reference to this in the archives or in the manuals. Thanks The contents of this e-mail are confidential and for the exclusive use of the intended recipient.

Some question about SIMtrace2

by 小葱

Dear Engineer, I have a few questions regarding simtrace2-cardem-pcsc that I would like to consult with you: （1）、I am using simtrace2-cardem-pcsc to access a remote SIM card by connecting the SIMtrace2 board to a mobile terminal. When I use pcsc_scan, it shows that the card reader has opened the SIM card successfully, and the other end is also connected to the SIMtrace2 board correctly. However, there are no valid APDU commands being printed. Through simtrace2-tool, I only see some reset information. （2）、I would like to connect the SIMTrace2 board to the soft SIM on my computer. Is there any related manual or documentation that could guide me through this process? I would greatly appreciate any advice you can provide when you have time. Thank you very much. Best regards, Peitao Jia 小葱 1256275333(a)qq.com

Banks PCSC transaction timeout with Card mute or absent

by James Tavares

Hello, I am having difficulty with a particular SIM card over osmo-remsim. On the bank daemon side, PCSC is timing out after 1 second on the same transaction (modemToCard: 81f2400202) after every reset. This behavior is very reliable and happens on every reset/initialization sequence from the modem. When I enable PCSC debugging, I see it is getting back the error CCID error 0xFE “Card absent or mute” from the CCID reader. When I use this card directly attached to the modem, everything is fine and the modem can go online (but I have no insight as to whether the modem is encountering an issue with the same APDU, or not).f When this transaction error occurs, osmo-remsim-bankd closes the connection, leading to a removal/insertion and card reset event. So, the system is in infinite loop of resetting the card, making a bunch of successful APDU transactions, timing out on the offending transaction, and then resetting again all over again... As an experiment, I changed osmo-remsim-bankd behavior to ignore the PCSC error, leave the connection open, and return a general error (0x6F 0x00) to the modem. When I do that, the modem periodically re-sends the offending APDU every few seconds, but, despite that, everything else is fine and the modem can now go online with this card over osmo-remsim. I’m thinking either card needs more time to answer this query, or perhaps it does not support this query at all. Based on some earlier troubleshooting it appears to be related to eSIM (eUICC) functionality. This particular card reports as an eSIM (side note: curiously, its EID is blank). When I use old modem firmware that does not support eSIM capabilities, the card works just fine over osmo-remsim. It is only when I upgrade the modem firmware to a version that supports eSIM that this problem appears. Other things I tried: - Upgrading to latest libccid and pcsc-lite — no change - Using a different card reader with different chip set — no change, and both are listed as “should be supported” by pcsc-lite. A couple questions: - Is there a way to change the timeout? I tried modifying libccid to set bBWI to 0xFF for this transaction (it was 0x00), but that had to effect. Internal timeouts within pcscd seem to be set to 3 seconds, and so I do not think they are coming into play, here. - What are your feelings on having osmo-remsim-bankd ignore this error and return a 0x6f 0x00? - Any other ideas? Here is the truncated log of traffic leading up to the offending APDU: local4.info: 2024-03-26 03:10:31.221037 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:793 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Tx RSPRO tpduCardToModem(621982054221001c0383026f408a01058b036f06058002005488009000) local4.info: 2024-03-26 03:10:31.228286 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:766 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Rx RSPRO tpduModemToCard(00b208bc3e) local4.info: 2024-03-26 03:10:31.242339 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:793 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Tx RSPRO tpduCardToModem(800101a40683010195010880015aa40683010a9501088401d4a40683010a950108ffffffffffffffffffffffffffffffffffffffffffffffffffffffffff9000) local4.info: 2024-03-26 03:10:31.250619 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:766 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Rx RSPRO tpduModemToCard(00b205043e) local4.info: 2024-03-26 03:10:31.255170 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:793 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Tx RSPRO tpduCardToModem(800103a406830101950108800158a40683010a9501088401d4a40683010a950108ffffffffffffffffffffffffffffffffffffffffffffffffffffffffff9000) local4.info: 2024-03-26 03:10:31.263534 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:766 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Rx RSPRO tpduModemToCard(00b209043e) local4.info: 2024-03-26 03:10:31.267873 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:793 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Tx RSPRO tpduCardToModem(800101a406830101950108800102a406830181950108800158a40683010a9501088401d4a40683010a950108ffffffffffffffffffffffffffffffffffff9000) local4.info: 2024-03-26 03:10:31.276622 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:766 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Rx RSPRO tpduModemToCard(00b206043e) local4.info: 2024-03-26 03:10:31.280369 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:793 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Tx RSPRO tpduCardToModem(8001019000800102a406830101950108800158a40683010a9501088401d4a40683010a950108ffffffffffffffffffffffffffffffffffffffffffffffff9000) local4.info: 2024-03-26 03:10:31.288355 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:766 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Rx RSPRO tpduModemToCard(00b201043e) local4.info: 2024-03-26 03:10:31.293560 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:793 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Tx RSPRO tpduCardToModem(800101900080015aa40683010a9501088401d4a40683010a950108ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff9000) local4.info: 2024-03-26 03:10:31.304765 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:766 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Rx RSPRO tpduModemToCard(00a40804047fff6fc6) local4.info: 2024-03-26 03:10:31.312115 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:793 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Tx RSPRO tpduCardToModem(611c) local4.info: 2024-03-26 03:10:31.316190 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:766 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Rx RSPRO tpduModemToCard(00c000001c) local4.info: 2024-03-26 03:10:31.319163 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:793 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Tx RSPRO tpduCardToModem(621a8205422100080183026fc68a01058b036f0601800200088801d09000) local4.info: 2024-03-26 03:10:31.328212 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:766 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Rx RSPRO tpduModemToCard(00a2010408ffffffffffffffff) local4.info: 2024-03-26 03:10:31.330957 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:793 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Tx RSPRO tpduCardToModem(6282) local4.info: 2024-03-26 03:10:31.335619 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_main.c:766 [000 B1:0 CONN_CLIENT_MAPPED_CARD] Rx RSPRO tpduModemToCard(81f2400202) local4.info: 2024-03-26 03:10:32.363083 bdu-arm-ce-imx8mp bankd-wrapper[1762]: 1763 DBANKDW INFO ../../../git/src/bankd/bankd_pcsc.c:319 [000 B1:0 CONN_CLIENT_MAPPED_CARD] SCardTransmit: Transaction failed.

pycrate repo update

by benoit michau

Dear osmocom developpers, This is just to let you know that the Python library pycrate has a new home : https://github.com/pycrate-org/pycrate. The packages on Pypi are now feeded from there. This library can be used in many cases dealing with mobile signalling. I wanted to let you know, as even if I am not aware of any osmocom projects depending on it, some of you may use the library from time to time, or could have local applications depending on it. Best Regards Benoit
