CC2538: CC2592 Front End configuration With CC2538

Part Number: CC2538
Other Parts Discussed in Thread: CC2592, Z-STACK,

Hello Everyone,

am using zstack ZNP application.

In Stack PA/LNA Configurations are:

/* PD2 -> HGM */

HAL_PA_LNA_RX_LGM();

/* PC3 -> PAEN */
RFC_OBS_CTRL0 = RFC_OBS_CTRL_PA_PD_INV; //0x68
OBSSEL3 = OBSSEL_OBS_CTRL0; //0X80

/* PC2 -> EN (LNA control) */
RFC_OBS_CTRL1 = RFC_OBS_CTRL_LNAMIX_PD_INV; // 0x6A
OBSSEL2 = OBSSEL_OBS_CTRL1; // 0x81

But the document AN130 - Using CC2592 Front End With CC2538 recommends the cc2538 registers setting in Table-11 as:

RFC_OBS_CTRL0 = 0x6A

OBSSEL3 = 0X81

RFC_OBS_CTRL1 = 0x68

OBSSEL2 = 0x80

So, my question is:

1) which settings are the correct one. stack's or document's???

2) My application requirements are High Tx power and high Rx sensitivity. what are the recommended settings?

I enable HAL_PA_LNA_CC2538 macro and  updated the firmware with default settings but the range is upto 8-10 m what am I doing wrong?

BR,

Moazam
