GPS send null position about lora_aprs_tracker

[richonguzman]

Hi,

can you tell me which board are you using?

my last firmware available for the Tracker is 2023.08.19 so this is strange

[iw2ejh]

ops sorry, yes version is 2013-8-19, i named the directory with the date I download the fw.
The board is 'ttgo-t-beam-v1' and fw is 2023-08-19

[richonguzman]

could it be you flashed another filesystem? or changed something when uploading the new firmware?

which version was the "before" version which has no flaws for you?

[iw2ejh]

version 2023-7-13 was the version I then updated to 2023-8-19 and the formed packet did not show the gps position. I then rolled back to version 2023-07-13 and the gps position in the packet was correct.
I then updated again to 2023-08-19 and got again the null? in the packet sent
you can see the trace in aprs.fi: https://aprs.fi/?c=raw&call=IW2EJH-5

Only thing i can have touched is the config file, i cup/paste the first part, I will try to reload with the original and run a new test.

Please update also the filesystem with the new data (not pasting the old) as new features has been added and this may be causing the problem

[iw2ejh]

I unzipped the FW in a new directory and changed manually the value in the tracker.config file, compiled,uploaded and uploaded filesystem, and now it work fine.
here is a extract of the syslog showing when the gps data was not sent correctly and after with the correct value:

still have a small glitch, but do not know when it appear because usually I do not keep the lcd display connected : the date and time is correct but the year/month/day is showing 1999-12-31 . is this something known or is is still an error in my config?

Maybe wait a little longer and tell me about it later.

Usually the time is the first to be received , then the date and finally the gps fix (and position)

[richonguzman]

did it got resolved?

[iw2ejh]

The "null?" packet sent out to aprs in the packet string is solved. The date displayed on the Oled is still at 1999-12-31. This is not important at the moment, I will program a new board for a friend tomorow and check if it work. I will update when test done.
