bluetoothWaveformConfig

Bluetooth BR/EDR waveform generator configuration parameters

Since R2020a

Description

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

Creation

Syntax

cfgWaveform = bluetoothWaveformConfig

cfg = bluetoothWaveformConfig(Name,Value)

Description

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

cfg = bluetoothWaveformConfig(Name,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.
