Android Question DJI OcuSyncLink class access [solved]

[madru]

Hi,

I try to get the getFrequencyBand from the SDK as described here: https://developer.dji.com/api-refer...ynclink_getfrequencybandwithcompletion_inline

unfortunately

OcuSyncLink.RunMethod("getFrequencyBand", Array(cc))

fails with no reason, what am I doing wrong?

Sub getFrequencyBand As ResumableSub
    If aircraft.Connected Then
        Dim airlink As JavaObject = aircraft
        airlink = airlink.RunMethod("getAirLink", Null)
        If airlink.IsInitialized Then
            Dim OcuSyncLink As JavaObject = airlink.RunMethod("getOcuSyncLink", Null)
            If OcuSyncLink.IsInitialized Then
                Dim cc As Object = OcuSyncLink.CreateEventFromUI("dji.common.util.CommonCallbacks$CompletionCallbackWith", "callback", Null)
                OcuSyncLink.RunMethod("getFrequencyBand", Array(cc))' not workin no cc
                Wait For (OcuSyncLink) Callback_Event (MethodName As String, Args() As Object) ' always failure
                If MethodName = "onSuccess" Then
                    Log("getFrequencyBand "&Args(0))
                    Return Args(0)
                Else
                    Log("OcuSyncLink onSuccess getFrequencyBand failed")
                End If
            End If
        End If
    Else
        Log("not connected")
    End If
End Sub

using the same code (replacing OcuSync with Lightbride) with a Lightbridhe drone does work, so the code must be OK. No idea why a Mavic Pro returns nothing.....
