2021-11-03 07:29:15 INFO: [364bd227] disconnectedI upgrade today to the latest version 4.14
Have you tried latest master?
How can i try?
You'd have to build from the source.
replace the files installed with the build? that i've done.
Sorry i'm not the expert :(
You did a build from master and replaced the JAR file? And restarted service then, right? If it's still doesn't work, it's probably not supported yet.
I have one of these TK905 4G devices too, I find it talks h02 rather than watch like the previous versions.
It seems to have a bug when it goes to sleep though as it jumps to the ocean until it detects movement again so I suspect this device not quite adhering to h02 but similar.
I've got a new version of a TkStar GPS tracker. Before i had the TK905B now the version TK905B-4GSA. In traccar he blinks green but didn't give his info. In my log i see the next error:
Does anyone know the solution?
