		float	band = `4`
	)

Sets carrier frequency. Allowed values are in range from 150.0 to 960.0 MHz. Will automatically perform image calibration if the frequency changes by more than RADIOLIB_LR11X0_CAL_IMG_FREQ_TRIG MHz.

Parameters

freq	Carrier frequency to be set in MHz.
skipCalibration	Skip automated image calibration.
band	Half bandwidth for image calibration. For example, if carrier is 434 MHz and band is set to 4 MHz, then the image will be calibrate for band 430 - 438 MHz. Unused if calibrate is set to false, defaults to 4 MHz

Returns: Status Codes

◆ setModem()

int16_t LR1110::setModem ( ModemType_t modem )

overridevirtual

Set modem for the radio to use. Will perform full reset and reconfigure the radio using its default parameters.

Parameters

modem Modem type to set - FSK, LoRa or LR-FHSS.

Returns: Status Codes

Reimplemented from PhysicalLayer.

◆ setOutputPower() [1/2]

int16_t LR1110::setOutputPower ( int8_t power )

overridevirtual

Sets output power. Allowed values are in range from -9 to 22 dBm (high-power PA) or -17 to 14 dBm (low-power PA).

Parameters

power Output power to be set in dBm, output PA is determined automatically preferring the low-power PA.

Returns: Status Codes

Reimplemented from PhysicalLayer.

◆ setOutputPower() [2/2]

int16_t LR1110::setOutputPower	(	int8_t	power,
		bool	forceHighPower
	)

Sets output power. Allowed values are in range from -9 to 22 dBm (high-power PA) or -17 to 14 dBm (low-power PA).

Parameters

power	Output power to be set in dBm.
forceHighPower	Force using the high-power PA. If set to false, PA will be determined automatically based on configured output power, preferring the low-power PA. If set to true, only high-power PA will be used.

Returns: Status Codes
