If no satellite fix use LBS instead

Hi Anton,

Link is https://we.tl/t-7I2YCLTmk3

I see two spots in the upro protocol that an invalid GPS signal could be picked up from.

1. 3.1 Location data(34 BYTES) - "F" <-GPS Flag unprecise or precise positioning
2. 3.4 Signal strength（4 BYTES）"D2D3" <-GPS Satellite number

Thanks

It was decoded incorrectly. Un-precise position presumably means invalid:

Hi Anton,

Sorry for the silly question, does this mean with the next compile we should see the LBS data being used if "F" flags as unprecise positioning?

Thanks

I think so, but you need to enable geolocation for invalid positions.

Perfect, Next update I will let you know how it goes.

For geolocation I have these setting already running.

<entry key='geolocation.enable'>true</entry>
<entry key='geolocation.type'>google</entry>
<entry key='geolocation.key'>XXX Key</entry>

Thanks

Hi Anton,

Apologies it have been a while and only getting back to this.

I have done the latest Traccar update and now the valid satellite fix is "No" which is good. https://ibb.co/3chBX8t

But the LBS still doesn't appear to be working. Any ideas on what to look at next?

Have double checked the Geolocation entry - https://ibb.co/FgYDCNV

Have you tried any other providers?

Hi Anton,

Yes I have tried both Google and OpenCelliD.

Thanks
Trent

Have you enabled geolocation for invalid positions?

Hi Anton,

Just checking this is what you mean my enabled?

I mean geolocation.processInvalidPositions config parameter.
