Hello,
I repost here my topic in the right place :)
I have a litte problem.
This morning I was able to track my vehicle but this evening it appears as offline. When I check the logs (hosted traccar on my server) I only see handshakes requests, with no location.
I always get the same handshake :
Hex : 283032373034343635393536334250303033353532323730343436353935363348534f31613429
Ascii : 027044659563BP00355227044659563HSO1a4
So BP00 -> handshake.
I've tested with https://github.com/freshworkstudio/gps-google-maps-socket-io and I can see the same problem :
Received : (027044659563BP00355227044659563HSO1a4) (handshake from tracker to server)
Sending : (027044659563AP01HSO) (handshake response from server to tracker)
The protocol is TK103 and this is my tracker : https://www.xcsource.com/ah207-mini-gps-gsm-gprs-tracker
I hope it the good place to send my problem, if it's not I'm sorry could you please tell me where I can ask this problem ?
Sorry for bad english.
Have a good day :)

I've masked the GPS coordinates but maybe others chars sorry
And now i got only location (BR00) messages.
Somebody has any idea ?
3rd message :
Since 3 minutes now I had 7 handshake requests, no position anymore.
And now i've had a lot of positions requests (+20) in 3 minutes so it's working
very strange
I've figured out that this problem happens when my tracker server has crashed during a trip because a request from the tracker was too big (multiple positions in a single request). And so after a restarting i got only handshakes.
Are you saying that Traccar crashed because device sent several messages at a time? Please provide proof.
Hello Anton,
Thanks for your answer :)
I've forgot to mentionned I used it on a custom node server test but it did the same thing on traccar (no crash but get no position only handshake).
