Hello again

[ptrk...@gmail.com]

Hello everyone after long (few years) period.

I noticed there is a ton of spam regarding psychoactive substances that google filters are happy to pass.

I want to let you all know that I'm trying to fight this. One of basic steps I took is to lock posting to the list to members only (previously it was anyone on the internet).

Hope it helps.

Regarding other news:

I started porting gr-gsm to current GNU Radio. I did it starting from blocks that are core part and that I need now. If I'll have time I'll port more, but I want to do it with consideration if particular block/app is really needed/used by anyone. I don't want to copy all of the mess.

The porting is going on in the 'porting_to_3.11' branch. Other/stalled branches were archived as tags for historical record. The development is going back to gihub because when I have choice between non-free Microsoft owned platform or gerrit (on osmocom) I'll drop gerrit first. Honestly I hate the soul-sucking piece of garbage that gerrit is.

If someone needs to work with new GNU Radio and something is missing in 'porting_to_3.11' branch there are two options:
- port that part and make a pull request,

- use https://github.com/ptrkrysik/gr-gsm/pull/600 pull request. It works. I'm using it. It's biggest con for me is that it wasn't done by myself so by just integrating it I wouldn't understand what have changed + my plan is to drop unused stuff.

In the meantime travis-ci changed policy regarding open source projects. Now they don't accept every project from github that has the right license, but it's case-by-case now and requires interacting with them to get acceptance. So there are no automatic tests at the moment.

Also I'll never again say in a presentation that I'm 'PHD candidate' because in the end I made the effort to actually finish the PHD ;).

Best Regards,

Piotr Krysik

Hey Piotr,

Thanks for the heads up, congratulations on the PhD, well deserved!

If you need any help with setting up CI/CD shoot me a mail, I might have some free time to check it and maybe do it.

Cheers,

Domi

anyone can help me please?

Hello Peter,

There is no this problem simply because burst file source and sink are
not ported.

Those are quite simple blocks:
https://github.com/ptrkrysik/gr-gsm/blob/master/lib/misc_utils/burst_file_source_impl.cc
https://github.com/ptrkrysik/gr-gsm/blob/master/lib/misc_utils/bursts_printer_impl.cc

If you're willing to port them I can help with this and with solving
this issue.

Best Regards,
Piotr Krysik

Hello Peter,

Thank you for the information. The include paths changed in the ported
version. The reason is that it is easier to work with gr-modtool when
they are not customized.

Here I forgot to change them but it still worked because I had non-clean
install.

I pushed the fixes.

Probably would be good to setup CI to avoid such mistakes in the future.

Best Regards,
Piotr Krysik

Hello Piotr,

thanks for your quick reply, i would port them, if i had the knowledge how to do it,

but i think it is not possible for me.

i even dont understand what you mean by this: Probably would be good to setup CI to avoid such mistakes in the future.

Hello Peter,

I've ported the burst_file_source and burst_file_sink.
After looking how convoluted creation of python bindings currently is in
connection with custom directory structure of gr-gsm I decided to do it
myself. If you are interested what was needed you can look at the
commit:
https://github.com/ptrkrysik/gr-gsm/commit/28ab805ab5ff18651e584af806837436694d0fc5

I'm not able to reproduce the described issue though. The ported blocks
just work.

Best Regards,
Piotr Krysik

Hello all,

Actually there is some issue. Burst_file_source sends lots of strange
messages. There is probably some issue with serialization or
de-serialization. Otherwise I don't know why they would appear.

Hello all,

There is a bug in GNU Radio PMT de-serialization. I described it here:
https://github.com/gnuradio/gnuradio/issues/6587#issuecomment-2603321113

and here:
https://github.com/gnuradio/gnuradio/issues/7672

As GSM bursts have constant length power of PMT's flexibility is not
needed here. I think we can safely get rid of PMT
serialization/de-serialization altogether from burst_file_source/sink.

Best Regards,
Piotr Krysik

Great, that the work at gr-gsm is continued!

Btw, can someone tell me if it is a bug, that the sdcch subslot splitter and filter are not working correctly when they placed  directly after the sdcch-demapper,

or are they only working when they are placed after the decoder?

Thanks for your help.

[Piotr Krysik]

Hello,

I don't use that block and I don't remember ever using it, so I didn't
port it. Today I pushed some changes i.e. with apps and blocks required
by them, but flow control blocks are not among them.

Best Regards,
Piotr Krysik
