Function Documentation

RAIL_Status_t RAIL_ConfigAntenna ( RAIL_Handle_t  railHandle,
const RAIL_AntennaConfig_t config 

Configures antenna path and pin locations.

This API must be called before any TX or RX takes place, otherwise the antenna configurations for those functions will not take effect.
[in]railHandleA RAIL instance handle.
[in]configA configuration structure applied to the relevant Antenna Configuration registers. A NULL config will produce undefined behavior.
Status code indicating success of the function call.

Although a RAIL handle is included for potential future expansion of this function, it is currently not used. That is, there is only one Antenna configuration that can be active on a chip, regardless of the number of protocols (unless the application updates the configuration upon a protocol switch), and the configuration is not saved in the RAIL instance. For optimal future compatibility, pass in a chip-specific handle, such as RAIL_EFR32_HANDLE.
