CC2530: CC2530 + RFX2401C Range Extender

Try to use the following code in macRadioTurnOnPower().

/* P1_1 -> PAEN */
RFC_OBS_CTRL0 = RFC_OBS_CTRL_PA_PD_INV;
OBSSEL1 = OBSSEL_OBS_CTRL0;

/* P1_4 -> EN (LNA control) */
RFC_OBS_CTRL1 = RFC_OBS_CTRL_LNAMIX_PD_INV;
OBSSEL4 = OBSSEL_OBS_CTRL1;

Ok. Also is there anything I need to do in the compiler options as well to enable the range extension feature for the RFX2401C?

Define HAL_PA_LNA in compile options but the TX table might be mismatch. You have to do TX table by yourself since you are using RFX2401 which is not a reference design provided by TI.

How and where do I do a TX table? What is the TX table supposed to do/be for?

When you define HAL_PA_LNA, it uses macRadioDefsTxPwCC2591[] as power table. Those register values in table is mapped and measured by spectrum analyzer.

1. Is TX the same as PAEN and RX as EN? Or is the other way around?

2. If I want to change the TX pin from P1.1 to P1.0, how would I change the code?

1. When you say the TX power table, are you only referring to the below image? Or is there more to the TX power table?

2. When and where are these values used in Z-Stack?

1. Yes
2. You can trace the code to know it.

In the CC2591 TX table, it says "characterized as X dBm in datasheet". Where are these values in the datasheet? I can't find them. Also how are these register values mapped? (How'd they come up with these hex values?)
