how to run osmocom-bb with grgsm in usrp b210 to connect openBTS?

by hellowangfang＠gmail.com

I used osmocom-bb and grgsm with usrp b210 to connect openBTS, but failed. The command is "./mobile -c /home/oi/wf/osmocom-bb/doc/examples/mobile/default.cfg","./trxcon -p 5075 " ,"grgsm_trx -p 5075" . When i used “./cell_log -A 1 ”， it could find plmn 1-1 with arfcn 1 which is same with openBTS. DSUM INFO cell_log.c:344 Sync ARFCN 1 (rxlev -105, 1 syncs left) DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:372 Measure from 1 to 1 DSUM INFO l1ctl.c:1177 start_pm L1CTL_PM_CONF DSUM INFO cell_log.c:400 start_pm S_L1CTL_PM_DONE DSUM INFO cell_log.c:363 Measurement done DSUM INFO cell_log.c:344 Sync ARFCN 1 (rxlev -105, 1 syncs left) DSUM INFO cell_log.c:190 Cell: ARFCN=1 MCC-MNC=001-01 (Test, Test) But when test with sim testcard 1, it failed to find the 1-1 cell.

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

Does anyone from the community want the airprobe.org domain?

by Harald Welte

Hi all, I was approached by the person currently holding the [unused] airprobe.org domain name. I guess it was at some point registered and intended to be used for the project (back in the pre-osmocom days). As far as I know it was never actually used for that. So the question is now if anyone wants to get that domain transferred in order to do something useful with it, or whether the current registrant should simply let it expire?

Powering GSM MS from USB

by Mychaela Falconia

Hello fellow GSM MS tinkerers, Question: is there anyone on either ML who has any experience with powering a GSM MS from USB, or had at least thought about this problem? We all know the fundamental problem: during Tx bursts the PA in a GSM MS can suck as much as 2 A, but the current budget of a classic USB port is only 500 mA. However, that 2 A current draw has a duty cycle of 1/8 of a TDMA frame, and the total energy transfer with 1/8 duty cycle bursts of 2 A (at a given voltage) is equivalent to 250 mA continuous draw - and the latter number is well within the range of what a PC/laptop USB host port can supply. Context: I am looking into the possibility of building a new GSM MS board that would be just a little better than the one in OS#4030. The goal is to produce a low-cost modem-only (no UI as in LCD etc, host computer required for control) GSM MS using a pre-existing packaged Calypso module (FC Tango, similar to GTM900, but a little better) with a built-in USB adapter for the two Calypso UARTs - very similar goals to OS#4030, but design it in such a way that will be suitable for both firmware tastes, rather than OBB-only. My initial thought was to require a separate non-USB supply for the GSM side of this board, leaving USB power only for the FT2232H block. This approach is not a problem from the perspective of cost - I already have a large stock of 3.6V 2.2A power supply bricks that were specifically made for powering FreeCalypso dev boards, hence the least-effort and least-cost approach would be to simply include one of these AC-to-3.6V adapters with each board and be done with it. But use convenience does suffer with this approach: in addition to connecting the GSM MS board to her PC/laptop with a USB cable, the user would also have to connect the separate 3.6V power supply (and have a spare AC power outlet for it) in order to bring the GSM MS to life. The whole arrangement would be much more convenient for the user if she only needs to connect USB from her PC/laptop to the board and that's it - have this USB supply power to the GSM MS and carry the two ttyUSB channels for Calypso UARTs. But how to design it in hw so that it will work correctly is the question. My first thought in this direction is to implement a step-down regulator (ideally a switcher, but linear may be OK too) from 5V down to 3.5V as the first order of business, and then somehow deal with 2 A current spikes on the 3.5V rail. Why 3.5V? Every power consumer inside a Calypso+Iota+Rita module either uses actual LDO linear regulators (Iota and Rita) or behaves (power-wise) in the manner of a linear regulator (RF PA), thus one could actually feed 5V directly to the VBAT input of such module - but this design would shorten the longevity of components through higher heat dissipation inside Iota, Rita and PA chips. If we stick a linear regulator down to 3.5V somewhere between USB 5V power input and VBAT rail to the Calypso module, the overall current and power consumption profile stays exactly the same, but a big chunk of heat dissipation moves from delicate RF components to that external 3.5V regulator, which can have a proper heat sink. (The specific choice of 3.5V number is rather arbitrary - the idea is to make it as low as possible while staying within safe margins of "good battery" voltage.) And if we make that 5V to 3.5V regulator a switcher instead of linear, we'll have a little less current drawn from the USB host for the same current into VBAT GSM domain. But what would be the right way to support 2 A current spikes during GSM Tx bursts? I reason that a large capacitor will need to be placed on the output of the 3.5V step-down regulator, one that will store enough energy to feed the PA during that hungry burst - any thoughts as to which type and size of capacitor would be most appropriate here? And the most important question, for people with more EE experience than me, and/or people who have already considered this problem: is this capacitor solution expected to work, or is the problem intractable in the sense that a USB-powered GSM MS, with the USB host limiting to 500 mA, will never be able to produce proper GSM Tx bursts at max power without tripping overcurrent shutdown on the USB host port? I would greatly appreciate some feedback on these ideas. M~ P.S. Suggestions to move to USB Type C and USB-PD won't be helpful - the dev board MUST be usable with traditional PC/laptop USB host ports that max out at 500 mA and never switch from 5V to any other voltage.

GSM MS boards on clearance: FC Caramel2

by Mychaela Falconia

Hello GSM MS communities, I have a large inventory of FC Caramel2 boards that are in need of loving homes. I mean these boards: https://www.freecalypso.org/members/falcon/Caramel2/c2-fully-assembled.jpeg For those who are familiar with FCDEV3B, Caramel2 boards are very similar: all FreeCalypso tools work exactly the same (even with the same -h fcfam target selector option), firmware functionality works exactly the same (fcdev3b and tangomdm fw builds are made from the same source, just minor electrical diffs between the two boards which the fw needs to know about), same AT command interface, same rvinterf, same everything. Vadim (fixeria) recently told me that he found FC to have better CSD support than any other commonly available commercial GSM modem - this aspect will work exactly the same on C2 as on FCDEV3B. And for those who have an irresistible need to be naughty boys and run naughty software, OBB can run on Tango/Caramel2 hardware too: https://gerrit.osmocom.org/c/osmocom-bb/+/34297 The main diff between FCDEV3B and Caramel2 is that C2 came out a little worse in terms of quality: * FCDEV3B analog audio circuits (loudspeaker and mic) came out very clean despite no special effort at design time: I never hear any "buzz" from rectified GSM RF in FCDEV3B analog audio. OTOH, with C2 the audio is dirty by default, and to get it mostly-clean, I have to insert a long coax between the antenna connector on the board and the actual antenna, to move the radiating element away from the analog audio circuits. * LEDs: the single green LED on FCDEV3B indicates 100% reliably if the chipset is switched-on or switched-off, but Caramel2 board LEDs sometimes exhibit erratic behaviour as a result of wayward current paths, as I explain in the Status Report and User's Guide document: https://www.freecalypso.org/pub/GSM/FreeCalypso/Tango/Caramel2-SR-UG-v1.2.p… Seeing that Caramel2 design is flawed, I won't be making any more of them: *if* I decide to produce another board in the future with similar functionality, it will need to be a new design, adding LVC buffers for proper PPD support (partial power-down) and reworking the audio circuits. In this light, the existing inventory of C2 boards needs to be put on clearance - they are just gathering dust right now, but they should be perfectly suitable for more casual users with less stringest quality requirements. I have enough stock to supply 12 complete kits consisting of: * Caramel2 main board; * FT2232D-based DUART28 adapter board; * Power adapter from universal AC (worldwide voltage and frequency range) to 3.6 VDC; * Possibly FC-HDS4 headset and quadband GSM antenna. Once again, this board is a *clearance* item - no more will be made, but the already-made ones are looking for loving homes. *IF* there is any community interest in these boards, I would be happy to ship a few to Sysmocom, to be further distributed via the webshop. It would also be helpful if those who are interested in these clearance boards (if any) could state what they would consider to be a fair price for a full kit as described above. M~ P.S. If anyone still does CalypsoBTS hacks, these boards would NOT be a good choice for it, as the Rx SAW filters are totally inaccessible to rework - all 4 SAW filters (for full quadband Rx) are integrated into a monolithic chip-like module from Epcos, which is then embedded into the TR-800 module which is not amenable at all to rework. However, if you merely wish to see what's inside that TR-800 module, without modifying it, we have published results of a complete PCB reverse eng job on it: https://www.freecalypso.org/pub/GSM/iWOW/TR800-reverse-eng-gerbers.tar.bz2 https://www.freecalypso.org/pub/GSM/FreeCalypso/Tango/FC-Tango-netlist.tar.…

Osmocom discourse as alternative to mailing lists

by Harald Welte

Dear Osmocom community, while many people with a long history in FOSS development have no issues at all with mailing lists as primary form of engaging with their community, they have undoubtedly fallen out of fashion in favor of various chat/messaging systems or web based forums. In Osmocom, we've just launched an installation of the discourse forum software available at https://discourse.osmocom.org/ providing an alternative to our traditional mailing lists at https://lists.osmocom.org/ We're looking forward to see whether this web-based approach will facilitate more and/or other people to engage with the Osmocom developer/contributor community. Feel free to join and get the discussions started. If there's a need for more categories or sub-categories, just let one of the moderators know and we can help with that. The old mailing lists will continue to remain available for those who prefer them. -- - Harald Welte <laforge(a)osmocom.org> https://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Do you think it is realisable ? Someone please correct me if I'm wrong on this detail, but it is my understanding that no mainstream commercial operator today (outside of personal enthusiast tinkerers in Osmocom and similar communities) issues native 2G SIM cards any more - instead all of their current SIM cards are actually USIM/ISIM, and if GSM 11.11 SIM operation is supported at all, it is only provided as a backward compatibility mode. I reason that these "modern" SIMs must be using Milenage in their native 3G/4G mode, thus their secret key material is not classic Ki, but K/Ki (128 bits) plus OPc (another 128 bits), for a total of 256 bits of secret key material. What happens when these "modern" SIMs are accessed via GSM 11.11 SIM protocol, or when 2G authentication is requested in a USIM session? I find it doubtful that they switch to COMP128 (any version) in this mode, instead I reason that they use 2G mode of Milenage, which still uses both K/Ki and OPc - thus the secret key material used even for 2G Kc and SRES generation from RAND is still 256 bits rather than 128. Again, someone please correct me if my reasoning is wrong here. M~

When i start the Transceiver on 2 Phones with this commands ./osmocon -p /dev/ttyUSB1 -m c123xor -s /tmp/osmocom_l2 -c /root/osmocom/osmocom-bb/src/target/firmware/board/compal_e88/trx.highram.bin ./osmocon -p /dev/ttyUSB2 -m c123xor -s /tmp/osmocom_l2.2 -c /root/osmocom/osmocom-bb/src/target/firmware/board/compal_e88/trx.highram.bin and sudo ./transceiver -e 1 -2 -a 47 -r 99 it throws an error which i can not solve. Maybe i am blind or something, but it doesn't work. I tried to kill the process but i can't find anything. The CLI gave me this error: ~/osmocom/osmocom-bb/src/host/layer23/src/transceiver# sudo ./transceiver -e 1 -2 -a 47 -r 99 47 41 1 <000c> l1ctl.c:77 Tx Reset Req (1) <000c> l1ctl_link.c:171 Sending: '0d 00 00 00 01 00 00 00 ' <000c> l1ctl.c:77 Tx Reset Req (1) <000c> l1ctl_link.c:171 Sending: '0d 00 00 00 01 00 00 00 ' Aborted Even when i try to start it with only 1 Phone, it doesn't run. There is a Problem, but i can't figure out what it is... I hope you can help me out for running my Transceiver or give me some hints. Thank you very much Sally

New phone discovery - Sony Ericsson K200i/K220i

by Vadim Yanitskiy

Hi Osmocom and FreeCalypso communities, I would like to disclose my recent discovery, which so far was discussed within a small group of Osmocom members and with Mychaela Falconia. ==== A bit of history ==== There exists a tool for flashing old Sony Ericsson phones called pstool (search for 'PSTool_SE_ODM_free' in your favorite search engine). It's a Windows executable with a custom GUI, and with some additional clarifications specifically for "big Russian specialists" :P Unlike the more famous SETool2 Lite, which does support a wide range of phones based on SEMC's own A1 DB2xxx and A2 DB3xxx chipsets, the pstool is limited to only a few phone models (all listed in GUI): * J100i, J110i, J120i, * K200i, K220i. Among them is Sony Ericsson J100i [1], a Calypso based phone designed by Compal, on which you can already run custom OsmocomBB or FreeCalypso firmware. Both J110i and J120i are likely variants of J100i with some minor differences (correct me if I am wrong). [1] https://osmocom.org/projects/baseband/wiki/SonyEricssonJ100i My curiosity was piqued when I saw K200i/K220i in the dropdown list of the pstool. I ordered a few phones on a local advertising site assuming that they may also be based on Calypso. And... yes, they are! ==== Hardware ==== For those who are interested to see the inside, here are some photos: https://people.osmocom.org/fixeria/dump/se_k200i/board/ Some highlights (from Mychaela's E-mail): * Calypso 751992A (C035, final DSP ROM version 3606, full 512 KiB IRAM), * RF: Familiar Iota TWL3025 ABB and Rita, PA SKY77318, * Flash: SPANSION S71PL129NB0HFW4B (16 MiB NOR + 4 Mib XRAM), * Winbond W56932DYX - probably a ringtone melody player? According to [2], K220i is identical to K200i with the only difference that the former has an FM radio receiver. If anyone has a K220i, I would be interested to see the board photos though. [2] https://mobile-review.com/review/sonyericsson-k200.shtml ==== Software ==== I was able to get the FreeCalypso loadagent running: https://people.osmocom.org/fixeria/dump/se_k200i/info.txt and managed to dump the raw flash contents: https://people.osmocom.org/fixeria/dump/se_k200i/K200i-fc-flash1.bin https://people.osmocom.org/fixeria/dump/se_k200i/K200i-fc-flash2.bin The DSP ROM is a well-known version 3606: https://people.osmocom.org/fixeria/dump/se_k200i/dspromdump.txt I was also able to get unmodified OsmocomBB layer1 firmware (the J100i variant) running and even got the basic Rx functionality working: * cell_log is able to find cells, * ccch_scan happily decodes BCCH/AGCH/PCH messages. What's really nice about the K200i is that (unlike the J100i) it has the Calypso boot ROM unlocked, just like Pirelli DP-L10 [3]. This makes it impossible to brick the phone by erasing the flash. [3] https://osmocom.org/projects/baseband/wiki/PirelliDPL10 ==== Summary ==== At the moment of writing this announcement, K200i is neither supported by OsmocomBB nor by FreeCalypso. The big problem here is that we could not find the board schematics, so we don't have sufficient knowledge on how the RFFE control signals are routed. Figuring this out (be it hw-based or fw-based approach) is quite a big effort, and I doubt there will be a commercial interest to sponsor this. In any case, I believe it's a nice *potential* target, so I created a wiki page [4] with all the relevant information about K200i. [4] https://osmocom.org/projects/baseband/wiki/SonyEricssonK200i Now I am giving the podium to Mychaela, I am sure she has more to say :P Best regards, Vadim.

RFC: OsmoDevCall restart: Your input required

by Harald Welte

Dear Osmocom community, your input is required in order to tune the re-launch of the OsmoDevCall talk series. One of the complaints before the suspension in Summer this year was that the "Friday night 8pm CEST" timeslot was not exactly ideal for several people. Finding a common denominator might be difficult, given that Osmocom is a dayjob for some, a hobby for most, and we're of course not all in the same time zone or even continent. So let's try to run a couple of polls to figure out: * What is the best day of the week for OsmoDevCall? https://bitpoll.de/poll/CEQnaQKEvO/ * What is the best time of day for OsmoDevCall? https://bitpoll.de/poll/59dgmzOocT/ * What is the best frequency of OsmoDevCall https://bitpoll.de/poll/8jyuRJB6Hb/ The polls are open until October 21st, 2021. I would appreciate a high turn-out so we have a good representation across our community to make an educated decision about the schedule of futur events. Can't wait to re-start OsmoDevCall!

My error is: make[1]: Entering directory '/home/user/osmocom-bb-sylvain-burst_ind/src/target/firmware' make[1]: *** No rule to make target 'include/tiffs.h', needed by 'board/compal_e88/init.o'. Stop. But even prebuilt VM dosent show BURST_IND when start ccch_scan. I have feeling that everything is firmware problem. Can somebody send me a link with prebult sylvain_ind firmware or even better link oo some upload service with prebuilt VM? I will be very thankfull and i am willing to pay for that and some explanation via chat or email. Thank you very much! Kind regards!

RFC: migrating git.osmocom.org to gitea?

by Harald Welte

Hi all! [please follow-up-to the openbsc(a)lists.osmocom.org mailing list, if there is any discussion, we don't want to drag it over tons of mailing lists in parallel] Some weeks ago, I created https://osmocom.org/issues/5397 but it seems nobody noticed the ticket or had any comments to it. So let me post this as RFC here on the mailing list: In the past, we had a gitolite/gitosis setup, which was fine in the early days of git, but it means that people cannot easily create new repositories, see who has permissions, and we cannot delegate ownership. Even updating SSH keys requires manual interaction of a sysadmin like me. I would therefore suggest to migrate git.osmocom.org to gitea[1] This would allow the following features: * users can self-create any number of personal repositories (like gitlab/github) * we can create 'organizations' along the line of reasonably independent osmocom member projects like op25, who can then manage their own repos/permissions/... * gitea can link to redmine wiki and redmine issue trackers (rather than using its own built-in) For those repositories hosted in gerrit (mainly CNI), we would still keep git.osmocom.org a read-only mirror, like we do it right now. For those repositories not hosted in gerrit, users/projects could then accept merge requests in gitea. Coupling this with 3rd party authentication via github/gitlab/etc should make it easier for the occasional contributor to submit changes. There is a downside, of course; A lot of repo URLs have to change. Most of our current repositories are at git.osmocom.org/project.git while gitea follows a git.osmocom.org/organization/project.git scheme. I'm not sure there is any way to help to mitigate this... Any thoughts, comments?

OsmoDevCon 2022 ?

by Harald Welte

Dear fellow Osmocom developers, as you all know, we've sadly had to skip OsmoDevCon 2020 and 2021, trying to compensate it at least to some extent with our OsmoDevCall every two weeks. The COVID-19 pandemic is far from over, and we don't know what the upcoming winter season will bring. Nevertheless, I think it would be a good idea to start a discussion of whether we should plan for an OsmoDevCon in 2022. I personally would say let's plan for the usual late April 2022 time frame, and if the pandemic situation deteriorates, we can still cancel it with something like one month lead time. I would also personally suggest to limit attendance to people who are fully vaccinated, and in addition do a self-test for all participants every morning. In terms of venue, we might also consider to move to a venue that allows better ventilation. Irrespective of the above we can also bring the air filters from the sysmocom office. So with that as an input statement, I would like to hear your opinion on the above proposals. Who would want to attend? Any complaints against the "vaccinated only plus daily self-tests in the morning" approach? Regards, Harald -- - Harald Welte <laforge(a)osmocom.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

OsmocomBB releases

by Denis 'GNUtoo' Carikli

Hi, As I understand it is now possible to have a full software GSM stack in software[1], with the stock osmocomBB since trx_toolkit target was merged in OsmocomBB. Many network side components have releases[2] and several distributions already have part of the osmocom stack packaged[3][4]. To me having releases for osmocomBB as well also look interesting as we could then more easily make packages for it. It could then be used to test the other components of the stack either with hardware[5] or with pure software, or to easily install and keep up to date the tools (osmocon, osmoload, etc). Would the osmocomBB be interested in doing releases? Or is there something that is preventing that from happening (lack of interest?, lack of time/volunteers?, technical issues?). References: ----------- [1]https://osmocom.org/projects/baseband/wiki/FakeTRX [2]https://projects.osmocom.org/news/152 [3]https://packages.debian.org/search?keywords=osmo&searchon=names&suite=sta… [4]https://packages.gentoo.org/packages/net-libs/libosmocore [5]As I understand, it would require either a test license or a specific hardware setup with cables, attenuator(s) and a duplexer/circulator and to enable transmit support.

MT Call procedure

by Amirhosein naseri

Hi everyone. In MT Call flow must be as below MS BTS <- Setup Call Confirmed -> <- Assignment Command Assignment Completed -> Alerting -> Connect-> but in implemented code in mnccms.c file immediately after sending Call Confirmed message, Alerting message is sent from MS to BTS , and this lead to ignorance of Assignment Command from BTS. WHY the procedure implemented as this ???

lists.osmocom.org migrated to mailman3

by Harald Welte

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.

And add some printf at voice.c when run bb, i used one c118, I can see that the voice data from L2/L3 to L1, and got some data from L1(the first char is 0xd) at l1ctr.c l1ctr_traffic_ind. All seem ok, but the called phone can not hear any data that LCR send, and the LCR also can not get any useful data. Especially I still can hear voice form C118 speaker that the called phone send, and the called phone can hear that the voice data the C118 michone send. But I already changed the audio mode in gsm48_rr.c at gsm48_rr_init. please give me some advice. best regards shrek

fed to LAPDm at all. So when you get a L2 packet from L1, instead of blindly feeding it to LAPDm, you should check a LPD handler table to know who to feed it to, and for normal channels there would only be handler for LAPDm and for CBCH channel there would be no LAPDm handler and only a LPD=01 handler. > In the future, we can also add the BTS-side implementation. I don't > think they can share much code, If they can't share code, then, I would make sure to mark the method to be 'ms' side so as to keep the namespace clear. Also, I would stick to the convention we used for sms and name it something like gsm412_ms_entity (and same for the methods) > but it might make sense to have both in the same place. That's not really the policy we used so far. Only shared code goes to libosmo-xxx If it ever comes a time where we need it in another project, it'll still be time to move it there then. > I can spin a patch series directly on top of osmocom-bb, but the > testcases will probably not make it. Why ? layer23 is auto-tools based as well, copying the test suite stuff from libosmocore shouldn't be too hard. Cheers, Sylvain

other but rather completely separate. And again from the spec, should you expect one or the other on a channel, you must ignore any packets with the wrong LPD. So AFAIK on a CBCH channel if you ever get a LPD=00 it should be ignored and not fed to a LAPDm processor. Same thing for a BTS side LAPDm instance if it receives a LPD=01 it should be ignored.

Wireshark. Tracing the code shows that it is waiting for some input which never comes. The only way to get things going again is to stop and restart ccch_scan. The issue has been briefly raised in two earlier emails from Altaf and Joshua with a reply from Sylvain which I have copied below. Although Sylvain explains the meaning of the error, no solution has been discussed so far as far as can find. Studying the code in various apps to see how they handle S_L1CTL_FBSB_ERR, it seems the only way to get it going is to restart the sync to ARFCN. I do it by copying code from app_cbch_sniff.c and inserting the following case option in signal_cb() in app_ccch_scan.c: case S_L1CTL_FBSB_ERR: > ms = ((osmobb_fbsb_res *) signal_data)->ms; > return l1ctl_tx_fbsb_req(ms, ms->test_arfcn, > L1CTL_FBSB_F_FB01SB, 100, 0, CCCH_MODE_COMBINED, > dbm2rxlev(-85)); Frankly I do not know what exactly l1ctl_tx_fbsb_req does, but it seems to work pretty well. Except *very rarely* I find that after processing this resync, ccch_scan gives repeated data corruptions messages like: <000c> l1ctl.c:238 Dropping frame with 78 bit errors repeating endlessly! Can Holger or Harald who have written ccch_scan please confirm if this is the correct way to fix the problem or if there is better solution? Can you please also insert the update in the ccch_scan code in the burst_ind branch so that others can benefit? Thanks in advance! B.
