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:

2021-11-03 07:29:15  WARN: [364bd227] error - For input string: "" - NumberFormatException (... < WatchProtocolDecoder:146 < *:253 < ExtendedObjectDecoder:52 < ... < WrapperContext:102 < ...)

Does anyone know the solution?

Please provide lines above that error in the log. Also, what version of Traccar are you using?

Have you tried latest master?

arrows19839 months ago

How can i try?

Anton Tananaev9 months ago

You'd have to build from the source.

arrows19839 months ago

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.
