Sinotrack ST-906L H02 protocol and GPRS commands
Have you checked with the device vendor or protocol documentation to see if it's an expected behavior?
Hi Anton, thank you for your quick response and for this amazing service you make available to everyone.
From the protocol documentation i see that for many commands i should expect a response, like with the engine restart, where the device responds correctly with the position toghether with the string S20,OK
But even if I send the info command i don't receive anything.
Just one question: i read in a github thread posted years ago that traccar ignores every response from the device that does not send the full data packet with the position.
Is that still so? It may explain why i can't see anything in the log file for the majority of commands. This is just a thought based on the long power consumption increase i see when i send any command. The shape of the current absorption waveform is identical to the one i have every 30 seconds where the tracker sends data, so i suspect it is sending something and maybe i just don't see it in the log file. I'm not really sure about this though.
In any case, i'll write an email to the manufacturer, maybe they'll be able to provide me with useful info.
Thank you again
We do support command results for some protocols, but even if it's not supported, you still have to see the response as the raw data. If you don't see that, it means the device is not responding for some reason.
Hi! NaxFM,
Just to share my experiences with SinoTrack ST-906L and ST-904L trackers which I am still trying to figure out the issues.
I am too facing the same similar issues like you do. The only TracCar Custom Command with works is "8040000 rodyeo.dyndns.org 5013" which changes the tracking server to my private TracCar 6.4 latest version and tracker device reboots.
All other "Custom Command" like ... "RESTART", "RCONF", "CXZT" ... fails to show the output results at device properties "Green Circle Triple Dots" icon followed by "More Details" device info.
But the "Green Circle Triple Dots", "More Details" options which my other SeeWorld S5L tracker shows perfectly except for one important command "PARAM#" which does not show results at "More Details".
But all SinoTrack SMS command shown on the user manual works on VIP.SinoTrack.com IoT Platform when performing query on "Device Triple Dot", "Device Function", " Text Transport" send command query. It fails to work on TracCar Server Custom Command platform.
Which I could not figure out the root cause as I have checked the TracCar server logs and nothing on the Custom Command send is shown.
Hope someone got a solution to this mysterious issue. Thanks for sharing. I have share with Anton Tananaev too of this issue but no luck on any solution so far.
Thanks anyway to Anton for the useful resourceful guide so far learned.
Rodney
Thank you both for your answer.
I have just sent an email to the manufacturer asking for more info and possibly for a list of all the supported commands. I'll keep you updated.
Thanks to Anton Tananaev for the informative response.

Dear Anton, Does this means we can view the response as raw data via our own Private TracCar Server Platform for example at https://rodyeo.dyndns.org:8082/reports/logs ... or via SSH Linux Terminal /opt/traccar/logs/tracker-server.log ... Or will there be a future TracCar features ... TracCar Device Console Terminal interface will be useful so we can see direct response like in SinoTrack Device Function, Text Transport Interface terminal?

Hi everyone,
I am using sinotrack as well and all commands are working for me using the same format as SMS.
You can get more information on this link: https://mundogps.org/comandos-gprs-del-h02/
Hi Dsuarez2,
May we know what product model are you using ST-???
And what is the firmware version your hardware firmware query via QZXT command?
You mean all command via SMS is also working full list via TracCar Device, Settings, Command?
Are you on latest version of TracCar 6.4 too?
Hi everyone, i'm pretty new here. I just finished setting up a server and the Sinotrack ST-906L tracker. It was all very easy.
Now i'm facing a problem: i want to use the GPRS commands from traccar server, but it seems that the only commands that work are the built in cut off engine and restart engine. Any other command does not receive any response from the device.
If i copy the engine cut off command from the log file and send it as a custom command it works, so i know that sending custom commands works. I also know for a fact that every command i send gets received correctly, because i monitor the power consumption of the tracker and I see a couple of seconds of high current consumption whenever i send a command.
I read all protocol documents i could find and i can't figure it out. I'm starting to suspect this particular device only responds to those two commands and nothing else. Commands sent via SMS work fine, but i want to avoid those because i pay for each SMS the device sends.
The protocol it uses is the H02 on port 5013.
This commands stops the engine and works fine
*HQ,<DEVICE ID>,S20,211200,1,1#, it also responds with an OK signal*HQ,<DEVICE ID>,S71,211324,22,20#This one, which is the built in command to change the update interval (20 seconds in this case), gets ignored and i don't see any reponse in the log file, and of course the update interval stays the old 30 seconds.If you have any experience or suggestions, please share them with me because it has been a couple of days and I tried everything i can think of
Thank you
