What is the whole thing ? The phone firmware has to be compiled by an ARM compiler, and if you use GNU ARM, you need Cygwin anyway. If you want to use a different compiler for the host software, you most certainly have to adjust quite a lot of the source code, expecially when using the Microsoft C compiler. And why use pipes instead of sockets, Windows has sockets. Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de

osmocom on windows
by eisencah eisenach 07 Oct '10

Hello everybody. I've done my reading on GSM these last months and have a general ideea how it works. I would like to try to run osmocom on Windows (hope don't get stoned for this :) ) I've been going throgh the files and see how interprocess communication is done (between osmocom and osmoload for example). Do you have any recommendation about what to use on windows as the interface between the 2 programs? Has anyone else tried it? Cheers, Mihai.

Hello Sylvain, On Mon, 4 Oct 2010 22:13:13 +0200, "Sylvain Munaut" <246tnt(a)gmail.com> wrote: > > And Dieter's code probably worked on some internal version of the code > that were never even commited on the public tree and he may not even > have any more ... Yes, exactly, this code was never commited. Its main purpose was to get the TCH up and running. BTW, I still do not fully understand what Marten wants to do: - send a TCH ? If yes, with which device, a BTS or a GSM testset like I did with the HP8922 ? If it is the HP8922, this sending of audio data over one the external connectors of the testset also works with a full MOC or MTC, so no need to hack anything. Just use Sylvain's TCH testing branch and perform a MOC or MTC. This of course works with any GSM phone, so no need to use OsmocomBB at all... - something else I have not understand yet which requires just TCH receiving and no signalling ? Or recieve the same TCH on multiple phones ? Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de

But than again, it's all up to your free time, which is > always too short. The code I used when I started to implement the TCH in Layer-1 will no longer work with the current version of OsmocomBB so it is of no help. This means I have to rewrite it and test it to be sure that it works as expected which will take some time, time as you already mentioned, is my free time and this free time is valuable. I have the impression that in this case a quite detailed explanation including a working example is necessary and some hints won't help but only result in more questions. Although it might sound harsh, but knowledge in GSM and being able to read/understand/modify foreign source code is necessary, noone can expect this to learn here by asking the list. If one takes OsmocomBB as it is and registers to a cell and makes a call, the logging output should give a lot of hints what calls to L1CTL have to be done.

Hello Marten, First of all please be aware that OsmocomBB is now in a state where it can be used for voice calls without any special tricks so there is no need to tune on the voice traffic of the HP8922 GSM testset, you can use the GSM testset as a normal basestation.

Hello, Thanks u all this gr8.. work .. forgive me for my little novice question.. most probably goes to Mr. Deiter.. but any one from list be kind enough help me from list.. I'm pretty new to Osmocombb i made a setup as advised on *Sun, 01 Aug 2010* blog. with hp8922. ===Q=== " You just "tune" to the right ARFCN and time slot (I don't use hopping during testing) and see that you get your code running." ===UQ== Q.1) i learned from wiki how to change ARFCN from Layer on application by using below command, but how to tune right TS ? ./layer23 -a 871 -i 127.0.0.1 Q.2) even If OsmocomBB Layer1 CTL is able to tune to right ARFCN and Time Slot, will i be able to listen what so ever broadcasting from HP8922 from C123 speaker or PC speaker. non-encrypted, debugging non-hopping) Q.3) what command and interface will be used to enter the frequency hoping parameter, in case i will use FH option? to tune OsmocomBB l1CTL Q.4) How to enter Minimalistic L1 interface, what is interface available to insert theses command to layer1 DEDIC_MODE_EST_REQ , LAYER1_RESET, DEDIC_MODE_DATA_IND thanks , Martin

Presenting at event.
by Andrew Back 24 Sep '10

24 Sep '10

Hello, I'm involved with an open source hardware user group based in London: http://oshug.org Our next meeting is on Thursday 21st October and for which the theme is radio. We have one confirmed speaker who will be presenting on OpenHPSDR, and wondered if there might be someone around London at that time who might be willing to do a presentation on OsmocomBB and/or OpenBSC. For more info on OSHUG see the website for details of previous talks and photos and video. Regards, Andrew -- Andrew Back mailto:arback@gmail.com

Suggestions regarding the SIM code
by Harald Welte 23 Sep '10

23 Sep '10

Hi! I just found some time to have a look at the recent commit history and had a look at the SIM related code and had the following suggestions: 1) split the definitions from GSM TS 11.11 into a separate header file from the definitions that are OsmocomBB specific, and move the 11.11 header file into libosmocore 2) use msgb's for SIM messages. This way we can avoid all those manual buffer[N] = M type assignments and rather use msgb_put() constructs 3) even if not going for suggestion '2', it might be good to add some kind of a inline function abstracting out all the blocks that look like + buffer[0] = GSM1111_CLASS_GSM; + buffer[1] = GSM1111_INST_TERMINAL_PROFILE; + buffer[2] = 0x00; + buffer[3] = 0x00; + buffer[4] = length; with something like a "sim_buf_init(buffer, GSM11_INST_TERMINAL_PROFILE);" Of course those are simply suggestions... maybe for the day where somebody on this list is feeling bored and is looking for a quick and easy task to resolve.
