Got this to work with http://www.allthingstalk.com/lorawan-track-and-trace with small hack

Maybe it was not the intention of the software to support other boards, but I got this to work on the track and trace board:http://www.allthingstalk.com/lorawan-track-and-trace

Had to make a small change to

//_speed = speed.toDouble();
_speed = speed.toInt();

and then it works fine for me. I could not get toDouble() to compile on my Arduino 1.8.4 IDE libs, but used toInt() instead.

It's not the Arduino IDE version that matters, but the version of ArduinoCore-samd (and our SodaqCore-samd which is a derivative of it). In version ArduinoCore-same 1.6.7 they introduced String.toDouble.

If you're using the SODAQ ONE board then you should be using the 1.6.14 of our SodaqCore-samd boards files.

Ah, thanks... Arduino development is quite new for me.

SOLVED
I'm using Arduino 1.8.5 on Win10 and couldn't see the Version 1.6.14.
My latest is 1.6.11, using this link http://downloads.sodaq.net/package_sodaq_samd_index.json

after deleating and reloading all board-links and reloading the board-index 1.6.14 is shown
and test_ublox_gps compiles without error

use _speed = speed.toFloat() instead to use toInt(). They have changed Double to Float in the latest versions
