TK915-4GSA New port and protocol change?

Elias Bouvin3 years ago

I'm running today my GPS units on my Qnap server and really loves Traccar Manager & Client. (Anton, keep up the good work, if you read this!!)

I have some TK915 units today with 3G and bought some TK915-4GSA, when they are starting to shut down the 3G in my region.

As I understand the TK915-4GSA has a different protocol then the TK915. My questions is following:

  • I guess that's possible to use another port for the device, but need to change/update some file with correct protocol for TK915-4GSA?
    if that's the case, do someone know the file and string that's needs to be updated?

I have read the "Implement of Protocol", but it seems to advance for me.

Thanks in advance.

Do you have protocol documentation or samples?

Elias Bouvin3 years ago

Thanks for your quick answer Anton, I will try to find it out. Before I have sorted it out, maybe this link could help out when you supported another guy with the TK915-4GSA?

Sounds like it should be supported then.

I have been going through this, and It seems also be a different in the protocol of TK915-4GSA and the unit i did refer to TK905-4GSA.

Thank you Anton very much for your support in this case. I have one follow up question but understand if you will not answer it.

I have Traccar installed in QNAP, is it possible to change some file directly, or need it be changed and complied? I have been looking through the folders without any sucess to find any file that looks that could keep the protocols...

Anyhow, thanks again! =)

It needs to be compiled.

Elias Bouvin3 years ago

Hi Anton,

Is this protocol compiled into the new windows 5.0 version? I did try with the TK915-4GSA in the "watch" protocol with port 5093, but get the same error as before?

Anton Tananaev3 years ago

It should be included in 5.0. Please provide logs.

Hope this will work?

Seems like it's not sending any GPS data.

Elias Bouvin3 years ago

Anton, really thanks for your fast respons and support. It works now, =) Sorry, but it seems was a fault I did do that did't send the postion.

Also I would say that it really nice version of traccar 5.0!
