GatorProtocol Duplicate Data packets
I need server log file and protocol documentation.
I have found the Error, we have to send reply to every position packet that sent by device.i think that part not included in traccar server(for Gator protocol).
you already have below protocol documents in your https://www.traccar.org/protocols/ page
(Gator vehicle tracker communication protocol.doc)
(S208 S228 protocolENGLISH-st.doc)
please refer GPRS data echo instruction－21
for more details.
As far as I can see, it's already implemented in Traccar server.
But device sends same packet for one minute.
Documentation is not very clean on when server has to send acknowledgement message.
I have contacted technical support of manufacture they said reply must sends to every position packet.
I have added response to every message.
Please tell me which traccar server update has this feature.
You can either wait for next release of compile it from source.
I can compile it from source where can i get it?
and also please leave a small guide to how to do it.
thanks lot
Have you tried to search for that information?
Thanks I have gone through that page,
if i download https://github.com/tananaev/traccar, will it have the new update?
Yes.
Hi Anton,
I am having a similar problem with the gator protocol. I am getting the position data, but it is sending multiple times at it is not receiving the acknowledgement response from the server. I have checked the code and it is sending a response and the log below show that it tries to respond but there seem to be an error sending. The device is using a UDP protocol, perhaps the problem is that it cannot send a reply because of UDP? Can you please let me know your thoughts on this? Is there anything else I should check?

Hi Anton,
I have few M508 devices that use GatorProtocol and its communicate via UDP.
I got multiple duplicate location packets in every 7 seconds for about 1min after that location is changed and sends duplicate location packets for new location.
im greatly appreciate If you can look into this.
Thanks.
