Mictrack MT710 (Tlt2h protocol) WiFi NullPointerException
This should fix the issue:
https://github.com/traccar/traccar/commit/e398778abace08beb3b6eea2de210b000944548e
Issue solved thanks.
There is some other noise in the log file still even though it seems Geolocation is working for WiFi data.

The fix did work for the MT710 device with WiFi data, but the MT700 device still has an issue with WiFi data:

Confirmed fixed, thanks again.
Traccar version 5.9
First device ever tested Mictrack MT710 was not working with Traccar, log file filled with NullPointerException errors. After troubleshooting I disabled AGPS and LBS on the device. Once it had GPS fix it reported just fine. This also happens with MT700 devices.
Turning AGPS and LBS back on the log file shows this:
Looking at Github issue tracker, there has been a few NullPointerException issues with Tlt2h. Is this another one, or am I missing something?
