Is there a reason you're not providing logs?
Do you need all logs? can I send tracker-server.log if you need - https://1drv.ms/f/s!Ag6WmFC1S-nvhfFvBa8Nfr_ol3TadA?e=ckT617

I tested your samples and they work just fine for me on the latest version of Traccar.
I'm on 6.1 too.
I have this position on Front-end: https://1drv.ms/i/s!Ag6WmFC1S-nviJlvxZ_CYsBdzAys4w?e=ICtL0w
position table/database - https://1drv.ms/i/s!Ag6WmFC1S-nviJlxN-KLoIj0qDy-og?e=p8d3ai
Device - https://1drv.ms/i/s!Ag6WmFC1S-nviJlweOR0n1ZNFjkL0A?e=S4ca1e
At front-end its online.
Device lastupdate is ok.
In position table, the last row is 26/04.
Then the issue is not with decoding, but somewhere else.
What we can try?
@Anton, Can you help me about it?
Device are decoding but don't save at database.
I don't have any other ideas.
Right, the step is - Decode and after save? and after this, update device field (lastupdate)
Only to answer to future problems..
I'm using Docker, restarted container and all work fine.
I don't know what was the problem. - I think cache(?)
Which port have you used? 5011? I can't make it work
Yes, 5011.
Can you check here - https://www.traccar.org/devices/
Your firewall was opened?
Device is online, position send (check raw/log), but last_position on device is 3 days ago.
Traccar version - 6.11
