Function Documentation

wiced_result_t wiced_external_pa_configure	(	wiced_bt_gpio_numbers_t	ctx_pin,
		wiced_bt_gpio_numbers_t	crx_pin,
		wiced_bt_gpio_numbers_t	csd_byp_pin,
		wiced_hal_epa_mode_t	epa_mode
	)

Normally the Front End Module (FEM) control signals would be defined in the platform_gpio_pins structure and the corresponding functions (WICED_EPA_CTX, WICED_EPA_CRX, and WICED_EPA_CSD) and are always enabled.

The wiced_external_pa library provides application developers more dynamic control of the FEM control signals. The wiced_external_pa_configure api configures, enables, disables external power amplifier control logic signals CTX, CRX(if used), and CSD/BYP(if used). See wiced_hal_epa_mode_t definition for more details. Must use LHL gpios.

Parameters

[in]	ctx_pin	: Tx control signal of external power amplifier.
[in]	crx_pin	: Rx control signal of external power amplifier if used. Use WICED_GPIO_NOT_USED if not used.
[in]	csd_byp_pin	: CSD or BYP control signal of external power amplifier if used. Use WICED_GPIO_NOT_USED if not used.

Returns

: WICED_SUCCESS, WICED_ERROR
