RAIL Recommended Utility#

This optional software component can be enabled to include a recommended collection of other optional RAIL utilities. There are two mutually-exclusive variants:

• sl_rail_util_recommended - for use with applications using RAIL 3 APIs. It recommends other RAIL 3 components.

• rail_util_init (deprecated) - for use with legacy RAIL 2.x applications. It recommends older RAIL 2.x components for backwards compatibility.

This RAIL utility attempts to identify those RAIL utilities most commonly used by applications. If a list of utilities different from what is auto-selected here is sought, this component must be removed from the project with the custom list manually being added to the project.

Common RAIL utilities recommended for general use include:

• Initialization

• Callbacks

• Protocol

• RAIL 3 Power Amplifier (PA) Utility or Power Amplifier (PA)

• Packet Trace Interface (PTI)

• Received Signal Strength Indicator (RSSI)

• Direct Memory Access (DMA)

  • This primarily accelerates radio initialization, so it is currently included only for dynamic multiprotocol (DMP) scenarios.
