    Syntax

    numElements = getNumElements(cfgAngle)

    Description

    numElements = getNumElements(cfgAngle) returns the number of elements in the array for the input Bluetooth® low energy (LE) angle estimation configuration object.

    example

    Examples

    Open Live Script

    Create a Bluetooth LE angle estimation configuration object, specifying a 2-by-3 URA.

    cfgAngle = bleAngleEstimateConfig('ArraySize',[2 3])
    cfgAngle = 
  bleAngleEstimateConfig with properties:

            ArraySize: [2 3]
       ElementSpacing: 0.5000
    EnableCustomArray: 0
         SlotDuration: 2
     SwitchingPattern: [1 2 3 4]

    Return the number of elements in the antenna array.

    numElements = getNumElements(cfgAngle)
    numElements = 
6

    Input Arguments

    collapse all

    Bluetooth LE angle estimation configuration object, specified as a bleAngleEstimateConfig object.

    Output Arguments

    collapse all

    Number of elements in the array, returned as a positive integer. If the SlotDuration property of the cfg input is 2 μs, the value of this output is in the range [2, 38]. If the SlotDuration property is 1 μs, the value of this output is in the range [2, 75].

    Data Types: double
