Compressed location details #82

Closed ON3JT closed 1 week ago

ON3JT commented 2 months ago

I noticed on the TTGO screen and in the syslog output that compressed data results in a longitude and latitude of 0.00N, 0.00E. The raw data is sent to the APRS IS servers without any problem, they handle it from there :-)

But is seems on screen that some stations are 5700 km away, while in reality it is just 4km. I had the problem too, so I attached a bit of ugly code : APRS_compressed.txt

I test first if it is compressed data, if so, then proceed to correct function.

I'll need to clarify it a bit. Using the tracker that also sends compressed data I didn't noticed the wrong location data. Some bug that it occures in rare situations?

Hi

Could it be that the gps data inserted in webconfig page was 0.0, 0.0?

Or wrong values with "," instead of "."

Some send data with 0.0 , 0.0 to avoid being seen

I added a file with details. I hope that it help to explain it a bit :-)

so, I should add the comment extracted from LoRaPacket and add it at the last part of the syslog log packet?

@ON3JT can you try "syslog-mod" branch which should deliver comment of compressed (base91) and not compressed gps data on Rx packets

let me know how it goes

this seems to bee solved, so closing
