No telemetry decoder .mat files

[jnunezortuno]

I'm trying to log tne GPS L1/CA NAV message adding following lines to the conf file:

TelemetryDecoder_1C.implementation=GPS_L1_CA_Telemetry_Decoder
TelemetryDecoder_1C.dump=true
TelemetryDecoder_1C.remove_dat=false

I get a fix after 40 seconds and obtain the .dat files, but there are no .mat files.

I'm using GNSS-SDR v0.0.18.

The matlab files are generate at program shutdown, not "just in time". You probably want to record some signal that demonstrates your desired condition and do a file playback of it. The program will terminate at end of file and you will get your .mat files.

[jnunezortuno]

Yes, I am using a generated time-limited signal. At the end of execution no .mat files are generated

[jwmelto]

See here. Your program must terminate cleanly (object destructors must fire) and you need BOTH .dump=true and .dump_mat=true

Added TelemetryDecoder_1C.dump_mat=true but still doesn't works for me

[jnunezortuno]

Actually a message indicating .mat file creation is generated by GNSS-SDR but there is no .mat files, only .dat files.

can you share your config and data file? I've never had issue with the .mat files before.

Here you have!
