Please run `legato version` on your target and then check the version of your toolchain. I think you may have a mismatch.

Hi @bengme00
Please can you be more specific on what you can’t do with Legato 16.10?
By the way, the bindings are looking OK in your adef, so the initial binding problem is certainly due to a version matching problem between the Legato version running on the device, and the one used to build your app.

Mmmm, release on this page is still the 16.07 one. Should be a matter of days to have it proposing the 16.10.1 firmware.
Firmware can be upgraded from DS as well. Just connect to the device, and use the **Flash Firmware** action from the toolbar.

Hello @bengme00 ,
This looks like issue is due to weak GPS signal. Please try to run the test where signal is strong.
You can use GNSS tool to know the first fix is obtained. ( [gnss - Legato Docs](http://legato.io/legato-docs/latest/toolsTarget_gnss.html) )
Referring to below explanation,
$GPGSV,2,1,08,01,40,083,46,02,17,308,41,12,07,344,39,14,22,228,45\*75
Where:
```
GSV Satellites in view
2 Number of sentences for full data
1 sentence 1 of 2
08 Number of satellites in view
01 Satellite PRN number
40 Elevation, degrees
083 Azimuth, degrees
46 SNR - higher is better
for up to 4 satellites per sentence
*75 the checksum data, always begins with *
```
We can see the SNR field is empty.
We can see the GPGSV, where SNR field in the provided issue link is empty.
The GNSS is not able to get the First fix and TTFF is not available.
This problem may arise due to the weak satellite signal, the GNSS engine may not able to get the proper fix.
