No WiFi Location

Hello,

I get Wi-Fi location from device when GPS is not available along with cellIDs, but it seems the location is not of wifi but just using the cellIds. Could you please point me to any documentation or anything that will help me understand how does traccar accepts the wifi parameters?

I get the following HEX from device: https://drive.google.com/open?id=0B7wdD7RPbznDR2NHcUVsNXNXUkE

I have enabled following in my config file:

<entry key='geocoder.enable'>true</entry>
<entry key='geocoder.type'>google</entry>
<entry key='geolocation.enable'>true</entry>
<entry key='geolocation.type'>google</entry>
<entry key='geolocation.key'>GOOGLE_KEY</entry>	 
<entry key='geolocation.processInvalidPositions'>true</entry>

I tried with and without this.

I tried to search location on http://cellidfinder.com/ by entering the cellid information that I get in HEX and its close to what traccar gives, so it seems traccar only using cellids to get the location and not the Wi-Fi, it could be because Wi-Fi info may not be in the same format as traccar expects. I tried searching forum but couldn’t find much info on this.

Please find the official protocol documentation here – https://drive.google.com/open?id=0B7wdD7RPbznDaENfQnNoWmFhVXM

Could you please help here?

Thanks,
Atul

Are you sure you are using latest version of Traccar?

Yes, 3.11. Infact I have tried with the latest source code [17th May, 2017] but I get the same result. Let me try to reinstall 3.11 version once again and give a try before you spend any time. If you can give any pointers to debug, that would be great!

Thanks,

Traccar didn't have support for the WT message. I've just added it. You can get latest code from GitHub to test.

Okay, thanks. Let me try with latest code.

I have tested with latest code & it works. Thanks for quick fix.

Hi Atul, could you share what tracker do you use that support Wifi and Cell reporting to Traccar? Thanks!

Robert - For now, only jTrack and Trackuino (Open Source Firmware) trackers are 100% compatible with Traccar and Wi_Fi/CellID location data.

Are you able to tell from database data (table tc_positions ?) that the location was provided by Wifi instead of GPS ?

Usually you can tell by the accuracy value, but not always.
