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.
[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. |
