[SOLVED] navigation.headingMagnetic issues

[topodom]

here is the result of the debug :

Code:

{ navigation.headingMagnetic: 1.31530016649, navigation.attitude.roll: -0.0498125188171, navigation.attitude.pitch: -0.0218765406024 }

if i move the sensor a little bit i get :

Code:

{ navigation.headingMagnetic: 1.41319958604, navigation.attitude.roll: -0.0522878579387, navigation.attitude.pitch: -0.0178265759421 }

meaning that navigation.headingMagnetic has values.
if i compare the values with the signalK diagnostic in openplotter, i get the same values for the roll and pich but for navigation.headingMagnetic i get 73 and 80 degrees ?

So two the issues become :

- why cant i get the value of navigation.headingMagnetic in a gauge or text UI ?
Now i know there is values to find i dug in around may node theni have noticed tha in the "merge values" node (the one after "Signal K delta values" node). I have two outputs and i was connected to the second one. when i put it on the first one then i have been able to get my values. Yes it's a stupid mistake, certainly a noobs mistake


- why the values of navigation.headingMagnetic are different ?
For this point i don't have answer, futher i have for instance :
signal K : 119 deg, navigation.headingMagnetic: 3.47877744026
quite weird !
