fem_tx_output_power_check()

int8_t fem_tx_output_power_check	(	int8_t	power,
		uint16_t	freq_mhz,
		bool	tx_power_ceiling
	)

#include <include/fem_al/fem_al.h>

Check a real Tx output power, for the SoC with the front-end module for given parameters.

Check if the requested output power can be achieved. This function returns the exact value or if this value is not available for given frequency, the closest greater or lower value to the requested output power.

Parameters

[in]	power	Tx power level to check.
[in]	freq_mhz	Frequency in MHz. The output power check is valid only for this frequency.
[in]	tx_power_ceiling	Flag to get the ceiling or floor of the requested transmit power level.

Returns

The real Tx output power in dBm, which can be achieved for the given frequency. It might be different than power and depending on tx_power_ceiling it can be greater or lower than the requested one.
