104Pro (Rewire Security UK) Heading, Altitude, Battery
Top photo is Traccar button two are the interface of the other company.
Do you have protocol documentation?
The parameters in question are these ones: 100%,0,,,,,,;. Unfortunately the document doesn't explain those fields.
Yes that documentation does appear to be wrong. I have emailed the manufacture to see if they can send me the protocol documentation.
I went out for a little drive today while a packet capture was running on the port the tracker is sending data into my network on.
Here are a couple of readouts:
imei:864925030157534,001,200625165017,,F,165017.00,A,{LAT REDACTED},N,{LON REDACTED},W,17.646,100%,351.09,,,,,,;imei:864925030157534,001,200625172927,,F,172927.00,A,{LAT REDACTED},N,{LON REDACTED},W,28.599,100%,191.07,,,,,,;I can now say that I think the 100% is battery level of the tracker & the next figure is the heading (0 if stationary). I don't think my device reports altitude.
This is what i have worked out so far:
| Index | Explanation | Expected | Notes |
|---|---|---|---|
| Header | Header | imei | |
| ID | IMEI Number | :{IMEI Number} | |
| 1 | Keywords | , | |
| 2 | Time | , | |
| 3 | SIM Card Number | , | |
| 4 | GPS Validity | ,F/L | F = GPS data is valid, L = No GPS signal |
| 5 | ??? | , | |
| 6 | ??? | ,A/V | Related to Index 4: If F this = A, If L this = V |
| 7 | Lattitude | , | |
| 8 | Lattitude Hemisphere | ,N/S | |
| 9 | Longitude | , | |
| 10 | Longitude Hesisphere | ,E/W | |
| 11 | Speed | , | |
| 12 | ??? | , | Likely tracker battery reading |
| 13 | Course | , | Course/Heading Degrees |
| 14 | ??? | , | |
| 15 | ??? | , | |

I'm not a Java programmer so don't really have a clue how to start testing/implamenting a new decoder.
You don't need a new decoder. You just need to update existing one. Is heading still not decoded? It seems like that's the only actionable item here.
Yes it seems like heading is still not decoded.
In the absence of the protocol thats probably the only fix at the moment.
I have a 104Pro from Rewire Security in the UK (https://www.rewiresecurity.co.uk/gps-tracker-tk-104-vehicle-car-tracker). I have successfully got this to connect to my Traccar instance using the gps103 driver but I am struggling to get some information out of the device:
Here is the decoded HEX out of the logs (redacted):
The tracking interface that Rewire Security use (https://gpslive.co.uk/) seem to be able to get the information i desire.
Is anyone able to shed some light or help please?
