Bug in: gr-gsm-maint-3.10_with_multiarfcn, burst file source not working!

[Andre]

Hello Group,

i use Ubuntu 22.04.1 LTS and GNU Radio 3.10.1.1 with gr-gsm-maint-3.10_with_multiarfcn.

When i use a simple flowgraph to record some burst with the "Burst File SInk", it is not possible to read the recorded file with the "Burst File Source".

It gives me the following error:

pmt::deserialize: malformed input stream, tag value = : 147

Older version work fine!

Anyone knows how to fix this? 

Please take a look at the attached screenshot.

Bye.

There is some bug with burst file source. I tried a lot and it didn't work. I am using the old version comple with pyinstaller.

Hmmm that is strange. Old grgsm is not supposed to work with gnuradio 10.

Have you downloaded grgsm sources for gnuradio 10?

What version of gr-gsm are you using?

Nvm I saw it in the subject line: gr-gsm-3.10. That is the right version.

It has been tested there. Maybe there is a problem with Ubuntu 22:(

However this is a runtime error. It has to do with your input.

I am not involved with grc, you might have to ask in their mailing list for that.

Or, since you have the sources, try grepping into these for yje error meassage.

This might give you an idea about what kind of error it is.
