Introduction
The Radio Software Bundle (RFLib) component for CC13x2, CC26x2, CC13x4 and CC26x4 consists of products that were previously hosted in different locations and distributed through TIDRIVERS, TIDRIVERS examples and DriverLib:
- The high-level RF driver
- SysConfig meta data for configuring the RF driver and the front-end
- SysConfig meta data for configuring radio PHYs
- Low-level radio access functions used by the RF driver
- RF Core firmware patches for various PHYs
- API documentation

RF Patches
RF settings and patches for device family cc13x1_cc26x1 are in alpha state. They are not fully characterized and have only been tested in a limited manner. Support for certain settings and PHYs may be removed in the future.
Please consider this content for evaluation purposes only.
Library Naming
The location of the precompiled RF libraries has moved to match the same pattern as other components in the SDK.
The old pattern will be deprecated in the 4th quarter 2021 release. Please migrate to the new library format before then.
- Old format:
source/ti/drivers/rf/lib/rf_multiMode_[device].[aem4f, am4f, am4fg, arm4f] - New format:
source/ti/drivers/rf/lib/[ccs, ticlang, gcc, iar]/m4f/rf_multiMode_[device].a
RF Sysconfig: Antenna Switch Hardware Changes
The antenna switch, available under “Use Hardware”, is required by P device boards (matching regex /CC....P/). To ensure correct RF performance, the correct value for this option is now selected by default in the UI, but not when adding the RF module in a config script.
Make sure this option is selected for correct RF performance. It must also be placed before any assignments related to the RF module for coex.
See snippet below to add correct hardware:
const RF = scripting.addModule("/ti/drivers/RF");
if (("board" in system.deviceData) && ("RF" in system.deviceData.board.components)) {
RF.$hardware = system.deviceData.board.components.RF;
}Change made to LP_CC2652PSIP:
- The antenna switch is removed as a board component. Any assignment to
RF.$hardwarewill result in error.
