    Description

    The bluetoothWaveformConfig object parameterizes the bluetoothWaveformGenerator function to generate a Bluetooth® basic rate/enhanced data rate (BR/EDR) waveform.

    Creation

    Syntax

    cfgWaveform = bluetoothWaveformConfig
    cfgWaveform = bluetoothWaveformConfig(PropertyName=Value)

    Description

    cfgWaveform = bluetoothWaveformConfig creates a default Bluetooth BR/EDR waveform generator configuration object, cfgWaveform.

    example

    cfgWaveform = bluetoothWaveformConfig(PropertyName=Value) sets properties by using one or more name-value pairs. Enclose each property name in quotes. For example, (Mode="EDR3M") sets the physical layer (PHY) transmission mode to 3 Mbps.

    Data Types: string

    Payload length of packet, specified as an integer in the range [0, X], where X depends on the PacketType property. This value sets the number of bytes to be processed in a packet.

    Dependencies

    To enable this property, set the value of PacketType property to "DM1", "DH1", "DM3", "DH3", "DM5", "DH5", "AUX1", or "DV".

    Data Types: double

    Bluetooth device address, specified as a 12-element character vector or string scalar denoting a 6-octet hexadecimal value.

    Data Types: string

    Logical transport address for the packet, specified as a 3-bit binary column vector. This property indicates the active destination Peripheral for a packet in the Central-to-Peripheral transmission slot.

    Data Types: double

    Header control information, specified as a 3-bit binary column vector. This property indicates the header control information consisting of these three fields:

    Field Size of FieldField Information Indicates
    FLOW1 bitFlow control information
    ARQN1 bitAcknowledgment for successful reception of a cyclic redundancy check (CRC) packet
    SEQN1 bitSequencing scheme to order the packet stream

    Data Types: double

    Modulation index, specified as a scalar in the range [0.28, 0.35]. This property is the modulation index that the object uses when performing Gaussian frequency shift keying (GFSK) modulation or demodulation.

    Data Types: double

    Samples per symbol, specified as a positive integer. This value is used for GFSK modulation and demodulation.

    Data Types: double

    Data whiten status, specified as "On" or "Off". Set this value to "On" for the object to perform whitening on the header and payload bits.

    Data Types: string

    Whiten initialization, specified as a 7-bit binary column vector.

    Dependencies

    To enable this property, set the WhitenStatus property to "On".

    Data Types: double

    Logical link identifier, specified as a 2-bit binary column vector.

    Dependencies

    To enable this property, set the PacketType property to "DM1", "DH1", "DM3", "DH3", "DM5", "DH5", "AUX1", and "DV".

    Data Types: double

    Logical channel flow control indicator, specified as true or false.

    Dependencies

    To enable this property, set the value of PacketType property to "DM1", "DH1", "DM3", "DH3", "DM5", "DH5", "AUX1", and "DV".

    Data Types: logical

    Data type of the generated waveform, specified as "single" or "double". If you do not specify this input argument, the data type of waveform output is:

    • single when the data type of the data input is single

    • double when the data type of the data input is double or int8

    Data Types: char | string
