Dim gravity As List = no.RunMethod("getGravity:", Array(mot))
Dim gyro As List = no.RunMethod("getGyro:", Array(mot))
Dim magfld As List = no.RunMethod("getMagField:", Array(mot))
Dim magacc As List = no.RunMethod("getMagAccuracy:", Array(mot))
But I can find no reference to getGravity, getGyro, getMagField or getMagAccuracy in the documentation you so rightly point to.
My complete abject apologies for wasting your time.
Researching for my answer to Erel's post #4 I realized what I was doing wrong - the "get..." methods I was referring to in post #3 are to inline objective C code - for anyone who is interested have a look at the bottom of Erels code in MotionWithGravity.zip at:
