Static Methods

create

Returns a new serial port sensor.

class qgis.core.QgsSerialPortSensor

Bases: QgsIODeviceSensor

__init__(parent: QObject | None = None)

Constructor for a serial port sensor, bound to the specified parent.

Parameters:

parent (Optional[QObject] = None)

baudRate(self) → QSerialPort.BaudRate

Returns the baudrate of the serial port the sensor connects to.

Added in version 3.36.

Return type:

QSerialPort.BaudRate

static create(parent: QObject | None) → QgsSerialPortSensor | None

Returns a new serial port sensor.

The caller takes responsibility for deleting the returned object.

Parameters:

parent (Optional[QObject])

Return type:

Optional[QgsSerialPortSensor]

delimiter(self) → QByteArray

Returns the current delimiter used to separate data frames. If empty, each serial port data update will be considered a data frame.

Added in version 3.38.

Return type:

QByteArray

portName(self) → str

Returns the serial port the sensor connects to.

Return type:

str

setBaudRate(self, baudRate: QSerialPort.BaudRate)

Sets the baudrate of the serial port the sensor connects to.

Parameters:

baudRate (QSerialPort.BaudRate) – the baudrate (e.g. 9600)

Added in version 3.36.

setDelimiter(self, delimiter: QByteArray | bytes | bytearray)

Sets the delimiter used to identify data frames out of the data received from the serial port. If empty, each serial port data update will be considered a data frame.

Parameters:

delimiter (Union[QByteArray, bytes, bytearray]) – Character used to identify data frames

Added in version 3.38.

setPortName(self, portName: str | None)

Sets the serial port the sensor connects to.

Parameters:

portName (Optional[str]) – the port name (e.g. COM4)
