Debugging RF Output

As mentioned in the CC23xx SimpleLink Wireless MCU Technical Reference Manual, the RF output can be mapped to pins on the LaunchPad for RF signal debugging. These pins are intended to be used when connecting an RF range extender. However, they can also help in instances where it is unclear if the device is transmitting or receiving in the right window.

On the CC23xx or CC27xx, the RF observables should be enabled through SysConfig. In SysConfig -> TI DRIVERS -> RCL -> RCL Observables,

  • For Use Case select PA/LNA Pins

  • The settings for the Additional RF GPIO Signals should be automatically selected (RFEGPO0 (PA_EN) and RFEGPO1 (LNA_EN))

The DIO the signal is outputted on can then be configured under SysConfig -> TI DRIVERS -> RCL -> PinMux

  • LRF GPIO should be left to LRF

  • RFEGPO0 Pin should be set to the DIO wanted for the PA signal (Radio Tx)

  • RFEGPO0 Pin should be set to the DIO wanted for the LNA signal (Radio Rx)
